Add Wifi Control to your Garage Opener using Sonoff SV, ESPhome, and Home Assistant

DIY Smart Garage Door Control, just keeps getting better. I made a couple improvements to this version. #1 Using ESPhome which directly connects to Home Assistant without going through MQTT broker. #2 Added a US Sensor to detect the presence or absence of a car in the garage.
NOTE: Some garage door systems send rolling codes so shorting the two terminals with the Sonoff SV won't cut it. What you can do in this case is adding a compatible button and shorting the terminals that are in that button instead. More information can be found in this subreddit

You are awesome Doc! This was my first and long awaited dive into the home automation world and I think I have impressed my family, they now can open/close and see the state of the garage door with their phones from anywhere. I don't think I can thank you enough for your HA videos, I like your style. This went pretty smooth with maybe the exception of getting duckdns working, I struggled with that a little. Thanks again.

[@DrZzs]

Excellent! Glad to help!

[@firepilot17]

Thanks for the video! I used this to control my garage door, added a temperature sensor, and used another one of your videos to place the US sensor on the ceiling to tell me if the garage door is up. The only problem I had was with the FTDi adapter. My computer had an issue with the driver and I had to search around to correct that. In the end it all worked out. Thanks!

Well done Doc. I updated my sonoff SV last night version 3. Working flawlessly on the test bench. Today I installed it onto my door, I had a few problems with MY connections, but I worked them out and now its complete. Well done Sir. Waiting on version 4 with stop assist and LEDs.

Finding projects to do in self isolation. I just finished my install and works great. Made a mod to the SV board and freed up GPIO13. This gave me an extra input which I used for a second reed switch to confirm door is closed. Did this because I have an IR beam across the doorway which can stop it from closing if something or someone is under the door. Maybe GPIO13 could be used for the CO sensor. Cheers from Oz.

@@DrZzs so we can be ready with all the needed parts on hand, can you give us a complete parts/affiliate links list? Looking forward to the latest version! Other ideas I could find useful/suggest would be water leak detection for an overflowing/clogged ac drain pan.

For some reason the one installed in my system stopped working so I' ordered a replacement, but still need to install it. Connecting it to HA would be a good upgrade along with maybe 1 or more additional water sensors for redundancy ! It's always nice to know there is a minor problem before it potentially becomes a bigger one!

[@JHBVDS]

Hey DrZzs Thanks for the effort you put in in making your videos and sharing your knowledge! Having one magnetic sensor on a door, is certainly better than none, but being in Africa, we need something better. One sensor only tells you when the door is FULLY closed, but helps nothing to tell you if the door is stuck somewhere between open and close! I was hoping that you would like to make a further iteration of your opener/controller. I'm thinking of a opener which has two magnetic sensors, one to sense the fully open position and another for the fully closed position. PS: I think your idea with the ultrasonic sensor is great! Perhaps you can also use it to sense if there is an obstruction in the doorway 😃

[@randyarrasmith2013]

awesome project. I already had a zwave device for the door control but am adding a parking sensor with LEDs to indicate when I am parked where I want (in far enough but not too far). Side comment: if you snap a component off of a board you will most likely damage the solder pads making it very hard to put those components back on. I suggest for most people to simply use a soldering iron to heat up the resistor and then gently slide off with the screwdriver. You can then easily put them back on if you want if using the board for something else. :) I know all these boards are cheap now a days but still good practice :)

[@DrZzs]

good point! I'm not planning to reinstall those resistors, but that's a great tip for other times when we might want to reuse the parts. Thanks!

First of all, I want to thank you for all the videos and information that you share with us. I have learned a tremendous amount of knowledge from you and my automations are a success because of your guidance. I hope you can continue this for a long time. I do have a comment/suggestion regarding this implementation. As I was upgrading my garage openers, I realized that if for some reason the nodemcu (I used them instead of sonoff sv) looses power, by default the relay would trigger the doors. That's a major security problem, because the garage doors would be open after a power failure. I fixed this by adding the following line of code under the Switch definition. This way the switch never is on when power is restored. restore_mode: ALWAYS_OFF thanks again for all your work!!

[@DrZzs]

Awesome! Thanks for posting that. I'll include it in my v4 video!

[@steelcityking383]

Another awesome video. I added another ultrasonic sensor over top of the roof of the cars. When I tell Alexa I'm leaving I set up a script with a wait template and when the car pulls out the value from the ultrasonic sensor changes I add 5 seconds of delay then the garage closes its awesome.

I powered mine off the 12v from the garage door itself ... I just use it as a relay that I can control remotely ... I like it because it neatly fits inside my existing garage door controller box :) ...as for a ultrasonic sensor ... I have that in another box at the back of the room ... This works out car presence detection and distance to the wall when parking and flashes a light when the car is just far enough in for the garage door to close so I can have max space behind for other junk :)

[@TheBeefyTube]

Hey DrZzs, thought I would share the easy Shelly setup - I took your original setup and now replaced with a Shelly1 in 12v mode. You don't even have to flash it or break resistors. I use the stock firmware with built in timer to auto off after 0.2 seconds, so it works as momentary to activate the door and then use the button as a detached switch that works for the reed sensor. You could probably flash it and use the debug pins as other inputs.

[@acordill]

Great video as usual Dr. You can add a USB port from your NUC to your home assistant container. Attach FTDI adapter to a USB port on NUC, go to your container in proxmox, click on hardware, click add at top, select add usb device, I use add USB port on menu, from there pick the one with the FTDI adapter attached. Restart container, and you are golden!

good ideas. The best solution for auto-opening/closing is the MQTT Car Presence project. I'm still using mine. It's been about 18 months now, and it's still one of my favorite projects. kzbin.info/www/bejne/Z3Xck5-tqM-Zi5o

[@rustyherd3172]

Great video. I built something similar for my garage about a year ago. I used a vary similar range finder but connected it to a ESP32 dev board and it is mounted to the ceiling just above the door when it is open. This way if the distance is less than 5 cm it knows the door is open, 150 the car is there door closed, 200 car gone door close. This data is sent to a python program on my serve that tracks my wife's gps location on her phone. If she gets within a certain distance of the house it checks the sensor and determines what to do with the door.

Hi Justin, I've now used this solution for months using an NFC tag in the car to open the garage through Home Assistant. Great stuff, thanks. I would now like to add a radar motion sensor to that same module because it's conveniently in the middle of the garage. So I was wondering if there's any pins left on this layout to add the sensor? That would avoid dedicating an ESP32 module to that one extra sensor. Thanks in advance for the reply.

Version 4 needs to include a CO2 sensor that opens automatically the garage when levels of CO2 are too high and dangerous. ;)

[@DrZzs]

I love that! I'll look for a CO2 sensor. Last time I went looking they were kinda pricey. Of course, I drive an electric car so.... no fumes in the garage. Except MrZzs SUV. :)

[@brendankmurphy75]

CO would be more relevant. Carbon Monoxide (CO) is the deadly odorless gas that can kill people when they idle their cars in a closed garage. Carbon Dioxide (CO2) is the relatively acutely harmless greenhouse gas. In other words: CO will kill you from an idling car before CO2 will. This being said, you can detect CO with an MQ-7 sensor.

[@OldCurmudgeon3DP]

The issue w/ the position of the reed switch is you can only be sure if the door is fully open where you placed it or fully closed (I like this better) if it's at the other end. I almost wish I'd found HA before we got a commercial system. So many things I could do better, but the WAF during the transition at this point would be a mess.

[@DrZzs]

Fantastic video as always @DrZzs with a great straightforward approach to something many of us want to implement. Can I ask a question about an an issue I have please? Realize the video is getting older now but I can't seem to get the actual garage door working to open/ close in HA the door after I have implemented the project. I have got it all working and when it comes to the door opening/ closing the tests you show for the Sonoff SV red led light coming on when clicking on the button in HA that also works fine. The wires soldered to the Sonoff SV also trigger the door immediately to open/ close as you talk about when they are touched to the end points of the door motor mech. The issue I have is when the wires are connected to the door mech and I press the button in HA the door does not respond at all. Everything else works fine reed switch, US sensor, Red Led in Sonoff SV indicator on button press etc but the door won't budget after opening/ closing at the first point of contact when the wires are screwed in. Could my solder of the two wires on the Sonoff be an issue or something else obvious? Any help you or anyone else here can give would be very much appreciated.

[@moizqureshi1796]

Version 4 you should remove the magnetic door sensor. Instead, extend the jump cables for the ultra sonic distance sensor and place it on the ceiling. Far enough that when the garage door pulls up it covers the sensor. Now you can add two distance. One for the car and another for the garage door.

[@TheDannys19]

Doc, Love all your videos. I am still learning what the capabilities are of these devices. Is there a good reference of what you can connect to this board? For example, I want to connect a temperature sensor to it to make sure my water heater doesn’t freeze in the garage. Use any available GPIO (4 or 5)? Thanks!

[@DrZzs]

thanks! yes, you can use 4 or 5 for a temp sensor. ESPhome has support for many sensors. Come to discord if you get stuck.

[@gdreelin]

II was thinking it would be great to re-purpose some of those old outside keypads for garages to work with this new way of doing it. This would give you a backup in case HA is acting strange or just another way to get in your garage. My garage has one wired in for both doors but most times it does not work right and keeps losing the code. So replace it with something more high-tech that does the same using the wires.... A thought!

[@DrZzs]

I haven't tried incorporating the keypad... that's a good thought.

[@Nicoleise]

By this numbering scheme, I've build version 6 or so on an Arduino about a year ago. :) So if you want to skip some iterations, here are some useful ideas: - LED RGB Parking guide, collision warning and traffic light (I use AdaFruits circular addressable array) - User programmable/teachable desired parking position to let you park exactly in the right spot. - Ultrasonic parking distance and garage door automation (open the garage door once the car reverses about a feet, auto-close garage door after exit or when car is parked/clear) - Courtesey lights (traditional function; turn on with presense or open door if dark outside (gets signal from other controller) and if dark outside and reversing out, also turn on exterior spotlight.) - Alarm function to trigger alarm system if garage door is opened while armed, or if the vehicle is moving away from the ultrasonic sensor) So essentially, when you arrive home, the garage door needs to be opened by other means (button in car, WiFi connection or ALPR camera). The rest is automatic, the door closes behind you, and when you leave, it opens automatically and closes when you leave. You can obviously still monitor the state of the garage door and open/close it manually. I used an encoder to get the actual position of the door rather than the magnetic switches. If you use a magnetic switch, it's a good idea to either put one at both ends, or if only one, put it in the closed position. It's the closed position you'll want confirmation about, not "the door is not fully open". Especially not if you'd like to also use this sensor as an alarm. The encoder I programmed to be auto-adaptive so it self-learns the travel of the door and converts that to a percentage of opening. For the other stuff, I used the same ultrasonic sensor you used (but two of them, since it's a two-bay garage), and then integrated the garage door controller itself to get the encoder (position), the end switches, the command to open/close, and the safety IR beam that stops the door if a car or person is in the way, to register that the vehicle left the garage through a long enough interruption of the safety beam. The parking guide is off (energy conservation and less "eye clutter") until the garage door is opened and the distance is something like 3 m. It only reacts to "sloping change" so if you walk past the sensor, in most cases it doesn't react. Closer than 3 meters the LED array fills a circle of blue, then green, then yellow and then red. You stop when it's all reds. You should remember to take the deceleration of the car into account - the car will be moving faster at 3 meters than at 20 cm, so space the zones accordingly. :) If the distance is less than a certain threshold, the guide flashes red and the brightness is increased from 150 I think to 255, it's *really* good, you literally cannot not notice it. The parking guide turns off again, when the distance has been constant for ten seconds, unless the collision warning mode is active. When reversing out, it will show a red ring once you move the car a bit, and that turns to an animated red ring when the door is commanded to open, and a green constant ring when the door is either fully opened, or opened enough to clear the car (using the encoder position). When the car is monitored through the alarm system, the parking guide emits a solid ring red flash every five seconds to indicate the alarm function monitoring the car. In this instance, the auto-open is off and you need to disarm the alarm to move the car, otherwise the alarm will trigger, if you haven't already triggered it by opening a door or moving around in the garage. I hope this helps as a bit of inspiration. :) Oh - and be careful using cheap phone chargers for your house automation. A Danish bureau recently tested 40 non-OEM (not Samsung, Huawei, etc.) chargers bought in stores, and more than half had serious safety issues. Some of them would even catch on fire, even with no load attached.

[@gunnarbjru9685]

I like the idea of having an safety IR beam that stops the door if a car or person is in the way. And maybe a sound alarm telling persons in the garage that the door is closing. Something for the next version?

[@Nicoleise]

@@gunnarbjru9685 - It's typically mandantory in most of the EU, so in my case the IR beam was already on the garage door. Breaking the beam whilst closing causes the door to stop and then reverse to full open. :) If it isn't there already, it's inexpensive to add. I would never be without it. :)

[@gunnarbjru9685]

@@Nicoleise - I would like to have that on mine too. Unfortunately it does not have this feature. My garage door senses that it meet something and the load on the motor increases - but it uses quite a load until it gives up and returns.

[@Nicoleise]

​@@gunnarbjru9685 - Oh right. Our garage door does that too, but I don't think it's approved as enough protection on it's own anymore (might have been when the door was made). In any case, it does take quite an amount of force to stop the door. There's also another method which is suitable on it's own; a rubber profile (which usually exists anyways) along the edge of the door, but then with an air chamber inside it. If the rubber list is compressed, the air flow is detected from the profile being compressed against something. But both these methods will cause some damage (e.g. scratches to car paint), so I specifically wanted an IR beam. Like I said, it's not expensive if you want to retrofit it and your door supports it :)

Great video as always!! With the ultrasonic sensor reporting distances, you don't really need the reed switch, do you? You could base all the logic based on distance. Assuming Distance A>B>C, If the sensor reports distance C it means garage door is open. If the sensor reports distance B it means the door is closed and the car is present. If the sensor reports distance A, it means the door is closed and the car is not present

Having trouble with the open/close sensor. The relay trigger works well, but the door shows always closed in the panel. I've tried the reed switch and just bridging GPIO14 to ground with a straight wire off and on with no change. The log shows no reaction to anything with GPIO14. Any ideas? *EDIT* I changed to GPIO4 on the sonoff and changed the yaml to match and everything worked. I don't know if there's something wrong with my pin 14 or if something from an old setup still in the sonoff, but that was easy enough of a fix for anyone else who may run into something similar.

For the binary_sensor referencing GPIO14, do I need a add-on to use it? I've not referenced GPIO pins before. Device is a Sonoff SV with Tasmota firmware.

[@mattriding5588]

Thought...Instead of a read switch which can be difficult to install sometimes. Could you place the ultrasonic sensor pointing down above the door in the open position. Then you would have 3 distance readings. Short: door open. Medium: door closed and car in garage. Long: Door closed and no car in garage

[@jmyler]

Could i please ask fro your assistance in solving something for me, which i just cannot get my head around. With your MQTT version, i created an automation which triggered a LED flash cycle (on -> off each second), while the door was open. I have the LED attached on the TX pin of the SV, but cannot seem to grasp how to recreate the code in ESPHome.. Could you please help. thanks in advace

[@DrZzs]

cool! to set up a simple on/off led on a gpio pin in ESPhome this should tell you what you need to know: esphome.io/components/light/monochromatic.html For the output make it Tx (or GPIO1). That'll give you the light. Then if you want it to flash when the door is open you could probably use the binary_sensor "on_press" or "is_on", something like this: esphome.io/components/binary_sensor/index.html#binary-sensor-on-press you can list the actions. I'd have to play with it to really tell you exactly how to make it happen. But that should point you in the right direction. Good luck!

[@richf7148]

So, what would an automation look like to identify when a car is now in garage that wasn't a minute ago?

[@bawitdaba1337]

I'm not done setting mine up yet, but I had a lot of issues just flashing esphome. ESPHome flasher was detected as a virus (i guess this is a known issue according to the forums), ftdi drivers for windows was (not fun) to find and setup. At first I couldn't get the ESPHome binary to download from HA in chrome you have to shift+f5 if this happens. I could not for the life of me get ESPHome to connect to my hidden wifi network it needed to be configured as a bssid with fast_connect: true and a shorter password. Many hours later and 7 flashes later and it's actually online now, now on to the (what was supposed to be) hard part

Hey DrZzs, When you print gears for your mechanisms, what material do you use?

[@DrZzs]

PLA usually.

[@johnraahauge4552]

You might damage your Sonoff by hooking the echo pin from the Ultrasonic sensor directly to it. Remember it potentially gives up to 5v and the Sonoff GPIO is 3.3, so you should make a voltage divider with two resistors.

[@DrZzs]

ooh, that's a good point. I wonder if using a 3v US sensor would avoid that issue too?

[@johnraahauge4552]

@@DrZzs Yes, if you use a sensor that accepts 3v you won't have any problems. To be honest I don't really know if its that big of a deal. These devices are so cheap that it doesn't really break the bank if you fry one. Think they are pretty resilient. People hook up 5v inputs all the time and doesn't seem to have a big problem. Noticed Rob also did it with his temperature input on his Pool Controller.

[@sreed1073]

great video I do have one question how would I also add MQTT to the sketch as my kids and wife use an android app that sends an MQTT to publish the open the garage door command topic. other than that I would switch in a min.

[@DrZzs]

I should have also included the webhook shortcut button I put on my wife's phone. She wanted one quick button to press to open/close the garage. Sounds like what you've got with MQTT.

[@sreed1073]

@@DrZzs yes that is what I need do you have steps to add that

[@schololo-blog8762]

My sonoff SV stopped working after I soldered relay input pins. The led doesn't blink when I connect power (I don't connect to the relay switch but to board power as in video). Voltage is 4.9 and before soldering it worked. I tried on 2 sonoffs sv and both don't work now. Anyone help? Could it be because I overheated the board? There are no solder bridges.

[@BACRULES]

I What to make this so bad, but i have a big problem. I need it-sensor and Reed swish. how can i make it works so when the IR is broken the garage door going up and the reed swish will notice the door close or open. Any one have any ideas?

[@diederikmaes2367]

Hi Justin, is there a specific reason why you want to isolate the relay circuit by removing the resistors? Is this dependant on the type of garage relay switch or is this always necessary. I wanted to make sure I need to remove them. It'll be a pain getting them back on afterwards :-)

[@MrTjnielsen81]

I know this reply is a bit late to help you, but here's the answer in case somebody else needs to know: the garage door is configured to work with a physical momentary button, and it will toggle the motor when the trigger wire is grounded. The Sonoff SV is designed to work as a DC switch. In its factory state, it will not only use the power supply to run the electronics of the device itself, but also pass that voltage through the relay (as controlled by the user). If you connect the Sonoff SV's output directly to the garage door, you'll be supplying positive DC power into the garage door, not ground. Removing those little resistors isolates the DC power supply from the relay so it can operate entirely independently.

[@NicolasBoulanger]

this is the better version of garage opener :) ! is there any way to set cover position with this configuration ? thanks !

[@DrZzs]

no. You'd have to have a different motor system for that. Either a motor with an encoder that tracks how many times it has rotated, or a stepper motor that counts steps. Are you thinking of using it for something other than a garage door?

[@NicolasBoulanger]

DrZzs ok i prefer the esphome version for « management » its pretty cool no only for garage door :)

[@theguid0]

You could possibly time how long it takes to get to the position you wanted (if there was one spot in particular you wanted to allow pets in or something) and put a delay on that trigger. A second press when going up usually stops the door in place.

[@therealblujuice]

Version 4 yet?

[@areks4397]

I would suggest setting the Car presence as an automation: If the distance is less than 1.5 for X amount of time, car is present. That way you won't get false positives of people just passing by.

[@DrZzs]

good thought! Thanks

[@terencefaul]

Does anyone know how to change the yaml to make this in the form of a cover so there is one entity to show the state and a up down arrow either side for open and close

[@DrZzs]

I just saw a custom card that makes a cover out of any entity (at least I think that's what it does). github.com/custom-cards/cover-element it's available in the HA community store. Hope that's what you're looking for.

[@DanielNictheroy]

Tip for Mac Users!! I found a program to flash on Mac, that works like the "EZ Flash" for windows. It's called NodeMCU PyFlasher 4. I used to flash Sonoff, NodeMCU and D1Mini with no problem. In the past I had to install windows on my Mac just to use the EZ Flash from Dr Zzz recommendation, the other methods for Mac were complicated and didn't work well for me.

[@DrZzs]

Excellent!! Thanks!

[@eastfreakspl]

Hello. At end You mentioned something about v4. Is it available? I`m asking because i`m thinking about that kind of sensor with LEDs ;)

[@timnaylor9823]

Is there a compelling reason not to check more often with the sonic sensor? I use it to determine if the garage is open or closed as well. In my case, the sensor is on the main rail, and if it sees the door at

[@timnaylor9823]

also I used a nodemcu and a relay instead of the sonoff SV but basically the same YAML works with the tweaks for my specific garage door opener, and using the sonic sensor for double duty.

[@DrZzs]

no, I don't think it's a problem to check more often. I have some sensors that are reporting back every 10 seconds. Shouldn't be a problem. Good luck!

[@TheMisterTFM]

Broken links under parts section.

[@jeremyoberbroeckling9421]

Will this still work if you have the yellow learn button on your garage door opener?

[@OldCurmudgeon3DP]

It should since he paralleled the SV relay contact w/ the wall switch that controls the unit.

[@DrZzs]

I imagine it would. I don't know exactly what that learn button would do. My guess is it shouldn't come into play at all in this process. As Old Curmudgeon says, we're just connecting in parallel with the wall switch, so we're not asking your opener to change how it behaves with your existing remote control. Hope that helps.

[@colinbuckley5320]

For future readers with a yellow. It does not work. The wall panel isn't a simple switch, but a multi button panel with motion detection, garage door programming, etc. There are workarounds however. Some people open up a car remote and solder to that button. I chose to open the wall panel, found the button that opens the door, and wired directly to that.

[@danieleriksson3170]

Add an AI camera that reads the car plates for automatic opening. And a sensor that sees if something is under the door to automatically stop it (toys, kids, cars whatver can block its path)

[@DrZzs]

That would be awesome! I think someone has done something like that. At least the recognition of the Plates part.

[@lmamakos]

Urggh! You mercilessly tore the PCB pads and resistors off the board -- hurt so much to watch! Would have taken 2 seconds with a soldering iron to remove those parts, and you could actually restore them in the future if you ever wanted to.. Don't fear the soldering iron - mostly you just have to make sure to pick it up by the right end and you'l end up with more reliable results than those "Dupont" wires plugged in those header pins. Nice work! I'm using a different style ultrasonic sensor and ESPhome to measure my water softener's salt level. That sensor looks like what's embedded in car bumpers and is all nicely sealed up.

[@DrZzs]

Excellent! Sorry about the pcb resistors. Sometimes I like to break things. Zzulk Smash!!

[@JordanReese]

you can make a nice looking cover component with the following: that way you don't have a separate sensor and switch, just one nice garage door control switch: - platform: gpio pin: D2 name: "Garage Door Open Switch" id: door_switch internal: true inverted: yes - platform: restart name: "garage Restart" binary_sensor: - platform: gpio id: closed_stop internal: true pin: number: D6 mode: INPUT_PULLUP name: "closed_stop" device_class: garage_door filters: - invert: cover: - platform: template name: "Garage Door" lambda: |- if (id(closed_stop).state) { return cover::COVER_CLOSED; } else { return cover::COVER_OPEN; } open_action: # Turn the OPEN switch on briefly - switch.turn_on: door_switch - delay: 0.3s - switch.turn_off: door_switch close_action: - switch.turn_on: door_switch - delay: 0.3s - switch.turn_off: door_switch stop_action: - switch.turn_on: door_switch - delay: 0.3s - switch.turn_off: door_switch optimistic: true

thanks :) I've used cover for garage doors in the past. I went for something different this time on purpose.

ESPhome? No, Thank You. Smart Home is to make life easier. ESPhome is like tying shoes with one hand! TASMOTA rules!!!

[@EpicLPer]

ESPurna >>>> Tasmota

[@DrZzs]

really? Where does ESPhome fit in then? No MQTT, direct connection to Home Assistant API. Pretty easy to configure and update. I guess they each have their strengths.
