433mhz Sonoff RF Bridge using Tasmota and Portisch to scan Raw RF Codes for Zemismart Roller Shades

[@ohaizack6772]

I went ahead and flashed my RF Bridge R2 after the stream. Wanted to say that theres no need to sever those pathways to flash the RF chip. Just leave your USB to Serial/FDTI connected (or at least the 3v3 and GND wires) after flashing the first ESP chip, and power the bridge that way for the second flash. You only need to sever the 2 pathways for the RF chip flash if powering the bridge via the micro-usb port during the flash. After the RF chip flash, you are free to power the bridge by micro-usb again. This is also in the official Tasmota docs for the RF Bridge, but I guess we all missed it during the stream! The stream was great though, 2 action packed hours of sleuthing!

[@warfanax]

which position you keep the switch under LED to flash the RF chip? should it OFF or ON position to be able to flash RF chip the way you describe?

[@ohaizack6772]

@@warfanax I'm afraid I can't remember as it's been 4 months since, however I think it would be whichever position is specified in the official tasmota documentation on their website

[@CJ-vg4tg]

oh boy thank you! I watched your video 4 years ago and had this flashed to get curtain codes running 24/7 since then. Today I changed vlans and set the wrong ssid to the wrong vlan and it got stuck in limbo not being able o connect or reset. Had to reflash it. Wife could not open the gate today as it's used for this and other jobs.

[@willrnsantana]

Just followed your tutorial 'cause I've bought a zemismart motor too. Worked like a charm. Thank you so much

[@19c303b]

For those if you who can't flash because you receive md5 mismatch error, use 5v on the ftdi instead of 3.3v. Worked like a charm after many hours of frustration. (I have a CH340 flasher)

[@sdfhjklhsfdjdsflhkds]

Followed these instructions for my Zemismart blinds (non solar - very discreet) and they have been performing flawlessly since October. They haven't even been recharged yet. All the control is done in HA through Node Red as part of my overall lighting scheduling. Thanks for stepping through this in detail and highlighting these blinds (as did @The Hook Up). Your pain was my gain - all in all a home automation win!

[@jackofmosttrades.masterofsome]

Its a long shot, but if you see this message, I would love to know how you set this up in node red

[@sdfhjklhsfdjdsflhkds]

@@jackofmosttrades.masterofsome Putting aside the actual code scraping shown in DrZzs video and the Portisch information, the Node RED part was pretty straightforward. For each blind I created an Input Boolean to use as a manual switch in my dashboard. In Node-RED I also created two Switch nodes for each blind - one for up and one for down. Each Switch node contains the relevant code captured for the respective operation for the blind in the message payload (a long hex string) and the correct Sonoff Bridge command in the topic. In my automations, the blind is either commanded to go up or down (based on sun angle/azimuth, sunrise/sunset, heat warning, etc.). The switch node sends the command to the correct MQTT queue for the Sonoff Bridge AND toggles the Input Boolean to make sure that it always reflects the current blind state. It's easier to see than explain, so I have exported part of the Node-RED flow below that you can import and look at. I hope this helps!

Fantastic stuff DrZzs! For 3 years I've been trying to find a suitable solution to control my QMotion GenII blinds. I ended up connecting a 2 channel wifi relay to a spare remote but it always annoyed me that I could only open or close all the blinds at once. Now I've successfully flashed Tasmota and Portisch to an RF-bridge I can control each blind individually. Thanks for showing us how to do this. I would have been lost following the instructions on my own.

Thanks for the video. I used Tasmotizer but followed your general instructions and got there. With Portisch (the non-cut-trace version) I am now able to capture RF from my 6-speed and reverse ceiling fans. The old firmware did not twitch when I triggered those remotes. I can now work on linking the bedroom fan speed to temp overnight.

To get the Broadlink pro to read 433 you need the broadlink app then setup a user defined button in the app. Then hit sweep frequency and hold the button you want to learn until it picks it up, then the app will ask you to press the button again DON'T DO THAT. Do the Broadlink learn in HA then press the button. I found these instructions on the forums, it worked great on my cheap fan controllers.

[@rinaldiespera3424]

I got a couple of Zemismart roller blinds and able to control it with Portisch. What's depressing though after a couple of months (< 6mos), it stopped working. Issue is not with RF nor Homeassistant since it does not respond via its own remote too. Seems the roller blinds stopped responding to RF. Resetting the blinds does not bring it back to life. Tried opening it up and able to confirm that the dyno motor is still working. Now I got a couple of Zemismart roller blinds accumulating dust. Since the community is vibrant, am still hoping that somebody smarter managed to fix same issue as mine and kind enough to share. Tried getting support from Zemismart but nothing comes out of it yet.

If you are powering the device with a computer, OTG adaptor, or FTDI when you flash the RF chip you do not need to cut the traces. You cut the traces to prevent those two GPIOs from being shorted together when a "compliant" USB POWER only port is used since it shorts together D+ and D- (these traces). But everyone needs to learn how to cut a trace, and these are the two data lines from the USB plug that serve no purpose without a USBUART chip so I encourage everyone to give it a go.

[@TheHookUp]

Interestingly, I've never had a device that works in the sonoff RF bridge without using RFRAW, I just assumed it was a conspiracy against me.

Maybe turn off WiFi to it? My Google WiFi integration allows this.

[@hbosch5223]

How would you configure tasmota to just add the RF id payload into a URL you specify ?

[@ragnoto]

Would be interesting to see if you can also use this for a car remote. To for instance send out a lock-the-doors signal 15 minutes after comming home. Or when your home alarm goes to armed state. From what I can see my Mazda does use a 433Mhz key

[@JohnnieHougaardNielsen]

I'd be pretty surprised if your car remote has such excessively bad security that it would work with the RF bridge.

[@ragnoto]

Well if you can grab the raw data sent by the key and repeat that signal. There is no need for decryption or changing the signal.

[@JohnnieHougaardNielsen]

@@ragnoto Nope. The security features for car keyfobs stop this simplistic replay attack form working. Short version: Sent data change every time you use the keyfob.

Hi Dr Zzzz. Great videos. Flashed the sonoff bridge with tasmota as described. Flashed fine. It rebooted but I cannot find the IP. Used Fing and my router tool. Notthing under the name is appearing. Do I need to disconnect the flash cables, switch it back on and plug in the normal usb? Thanks

[@carlosnavarrolagos9443]

Hi everyone, bbconv.hrbl.pl/ isn't working ... anyone have a different option to get the code? thank you

[@kattz753]

Ohhhh…...I just finally got my Broadlink RF Pro today. I'm just about to take it out of the box and I hear in this video that the RF scanning isn't working. Is that still true? If so, I'll just pack it up and send it back to Amazon. I've got one Sonoff RF bridge. I can get another one and just get the IR Broadlink for my other remotes. I have more than 4 RF devices so I thought that the Broadlink would be good.

[@MrBlaster85]

Soooo, we now succesfully tested this service. The question now is, how do I configure this to use it?

[@erikmuller8512]

Can you send/reseve things with rolling code?

[@DrZzs]

I don't know for sure, but I don't think it would be usable with rolling codes.

[@sdfhjklhsfdjdsflhkds]

Yeah, I'm looking at Somfy (mainly for WAF) and the integration looks 'interesting' for this and other reasons. But @DrZzs has got me thinking ...

[@stevesmall3945]

DrZzs, is there an .stl file available for your pvc tube adapter?

[@rodneybrown5461]

Firstly thanks for your videos, truly helpful. Having a great time with HASS although my YAMLs are crap :) I tried this tasmota flash on my sonoff 433 RF Bridge today. I have flashed my 4ch sonoffs perfectly but this bridge failed to flash I used Tasmotizer and it backed the device up, erased memory to half way and the bar stopped. Message said this could take some time but eventually it returned an error "timed out, waiting for packet header". It does the same with ESP flasher. Any clues on this please. Had no problems with other sonoff basics so far. Regard Rodoz

[@MrJozza65]

Thanks for the instructions; I was always nervous about doing this but your demo has made me more confident. Would it be possible to do without severing the tracks on the circuit board by using a USB power only lead rather than one with data?

[@DrZzs]

I'd check the cable and make sure because I think in a power-only usb cable those data contacts might be shorted together. If that's true (and I really could be wrong here) that cable would still cause problems when trying to use pin 4/5 for flashing the RF chip.

[@JohnnieHougaardNielsen]

You do not need cutting any traces, if you have a USB/serial adapter to supply power, both while flashing Tasmota and also Portisch. USB to the RF Bridge only for normal operation.

[@MrJozza65]

Thanks for the suggestions; I am not sure why the tracks have to be cut and if it would affect normal operation; I guessed that there must be some good reason. I will have to try it out and see what happens. I have a spare Sonoff RF Bridge, so if magic smoke appeared or it gets bricked it's not the end of the world!

[@JohnnieHougaardNielsen]

@@MrJozza65 What you gain by cutting traces is: 1) The ability to power via USB while flashing. I prefer powering from USB/serial adapter while already attaching wires to the board. 2) The ability to expand with extra stuff (like sensors), as extra gpio pins are freed up if you have such urges. This is valid for flashing Tasmota, I'm not certain if additional consideration apply if flashing other firmware.

[@MrJozza65]

@@JohnnieHougaardNielsen Thanks, that makes it a bit clearer, so I will probably leave the trace cutting as I don't need the extra GPIO inputs at the moment and will power up with the adapter for flashing.

[@TheNCGardener]

I was able to duplicate a doorbell following this guide. It took all day to get it working. My new laptop does not like any of the flasher tools that I have. :-( The old laptop worked just fine. But I did get interrupted ALOT. Is there a video on how to use the data/codes in home assistant and nodered?

[@ciscomike82]

Hi everyone Does anyone get this error on flashing the portisch hex? Upload Failed Upload error code 211 Tasmota v9.2 Answer to my own question: I haven't set the SerialLog 0 command before flashing.. I just followed the short DrZzs's video and didn't mention that.

[@simfungreek]

Any luck in sniffing weather coded results from an RF433 sensor?

[@DrZzs]

I don't have that weather sensor. I would expect you could use this method to sniff any 433mhz codes. It would be a matter of knowing which information from the weather station corresponds to which raw codes.

[@stripeyhorse]

Better off using github.com/mverleun/RTL433-to-mqtt for weather stations. It’s made for it.. plus bonus it works with any 433 device.. I’ve tested aliexpress switches and pirs. Even picks up my cars tps.

[@Thamli]

Can you use this to steal RF remote codes for cars? Just realized this...

[@error53ish]

They'd have to operate at 433 Mhz.

[@DrZzs]

I don't think so, but I have a couple garage openers I could try....

[@Thamli]

Or your neighbours... Just as a precaution

[@austinmabry8462]

@@error53ish They also generally use a rolling code, so you'd only be able to steal the last code used, which is then useless, because it rolls over to the next code. It's theoretically possible to jam the frequency to keep the vehicle from receiving the code and rolling over, and then turn around and use that code once (and only once) at a later point, but it'd be tricky, considering that people are usually pretty close to their vehicle when they use their code; AND if it doesn't work, they'll just keep trying until it does. Unless you can just so happen to be in the right place when the vehicle is in code-learning mode, and new remotes are being synced, you're not gonna get any useful data. And at that point, you'd be just as easily able to sneak in there and program your own remote with its own rolling code anyway, so it'd be pointless. So from a practical standpoint the payoff for stealing a remote code for a keyless entry or garage door opener is virtually pointless outside of the movies.

[@JohnnieHougaardNielsen]

Car keyfobs have security features making them not work with the very basic RF Bridge. Otherwise it would be excessively bad security.

[@CS7-_-]

@DrZzs would it be possible for you to show us how to setup scripts in HA with the Sonoff RF Bridge with Portisch Firmware? Thanks - I followed all steps and I was successful!

[@felixh.7501]

Doc, this is a great refresh about rf433 and portish firmware, despite that the trend is to abandon this for zigbee & co, due to the statelessness. I was a bit shocked when you said you want to replace your great blind systems x7, done in a previous video. You said 3 out of 7 are no longer working. Rather than giving up so quickly the original idea, can you shortly make a video on what failed in the blinds motors design? When you said this i was on the way to reproduce your motor blinds for home...

[@MPElectronique]

hey, why 3 RFBridge ??

[@TheHellis]

What's up with the overhead camera? It looks like you record in slow motion and interpolate new frames in between.

[@DrZzs]

my PC was unhappy and that camera had some serious lag. It's usually better but to fix it I would have had to shut down OBS and restart it. Not ideal in the middle of a live stream. Sorry about that.

My ceiling fan remotes say they are 434mhz, would the 433mhz sonoff bridge still work with the fans?

[@annespacedroid]

The only way to know for sure is to try it. Do you have a broadlink rm pro? If so just capture the codes with that. If you don't have an rmpro, stay tuned. I have a spare sonoff Bridge I'm about to flash portisch on the rf side. Two of my fans codes were also not readable at all by the sonoff Bridge. Or my gate remote for that matter. Rmpro got them no problem & works awesome. About to flash a sonoff z-bridge, so I'll do portisch on a rf bridge & see what happens. Edit: both flashed successfully & the rf Bridge now reads my fans codes. ;-). (and a few others it never could) I'll still be using the rmpro though, never failed in many years.

[@annespacedroid]

Oops, didn't see 434mhz. 434mhz is not in the 433mhz range, so no would be the correct answer there. Sorry.

[@JohnnieHougaardNielsen]

433 MHz is actually 433.92 MHZ, which some round to 434, just to confuse people. It may work, but the very messy old RF signaling has so many variations that it may not work....

This is an Update. After following this video I was able to send commands to my fans from the sonoff RF bridge and everything worked. My ceiling fans are the "Hunter" brand in case someone is interested.

Hey Doc, Just recently got into Home automation and found your channel a god send. I managed to find the FTDI adapter online but not the cable that I connect with to the sonoff bridge, any idea where I can find this?

You can use a set of dupont jumper wires (good search term), probably female/male.

You can also flash your Sonoff with this open source version of RFlink : github.com/couin3/RFLink It is based on real RFlink sources and adapted for esp8266 and arduino. It works very well on Sonoff too, it recognize a lot of rf protocols natively and when your device is not recognized you can contact the Couin on github : He will make it compatible 😄
