Open Source Smart Home HUB 2.0 for Home Assistant

[@DrZzs]

Wow! I need this! Lets talk about mass production.

[@SmartSolutionsForHome]

WoW! DrZzs himself! I'm honored! :) Unfortunately, I'm "too small" to think about mass production. Maybe someday. But if you'd like to solder it yourself, I'll be more than happy to send you a set of PCBs. You inspired me to start this channel, so this is the least I could do to thank you.

[@krikkenstein]

Definitely needs mass production! Also I would like a inputs only version. Great work!

[@OldCurmudgeon3DP]

I wondered if you had seen this.

[@krikkenstein]

Forgot to add: power consumption would be a nice addition ;)

[@wd269]

Yeah, mass production is a great idea, but (there is always one of those) with mass production and sales comes product liability, UL and CE testing, etc., etc. Basically, if you buy one of these and install it, you could run into big financial problems. For example, house burns to ground (unless it's an underground WHobbit hole...then it just goes up in smoke) the insurance investigator attributes that fire to a non-UL/CE listed device and poof no insurance money for you....maybe

[@paunaiulian8628]

You want to thank us?! No man, we need to thank you for sharing your knowledge!

My pleasure! :)

Hi, impressive PCBs and assembly in this small package. The only thing missing from these designs are LEDs for each input / output. I work in BMS (Boulding Management System), something like SmatHome but for entire factories and large buildings. And the LEDs for the IO make diagnostics much easier if something is malfunctioning.

[@SmartSolutionsForHome]

There were LEDs in the previous revision of the HUB. I removed them deliberately and consciously :) As you can see, the HUB is locked in the box at all the time. So I wouldn't have noticed them anyway.

[@AlexusMaximusDE]

@@SmartSolutionsForHome While that is obviously your decision to make and may be sensible for your use case it is definitely a deficit, when considering you are also trying to sell it to others. Personally I think it would have been a better choice to make the LEDs optional since it costs basically nothing to add the traces and not use them, especially if you had already created them.

[@BenCos2018]

@@SmartSolutionsForHome add a small header for them maybe that way if people want them they can add them with a connecter to mount an led to the case for example

[@JohanLouwers]

@@SmartSolutionsForHome In all honesty, I would love to have more indicator LEDs. As from your video, you could have most behind the door, while "opening the door" would provide a much larger set of indicator LEDs. Having those really really really gives you a lot of quick "debug" options I would argue.

Sounds like some folks need to fork his files and add an led version

@@SmartSolutionsForHome it really is a fantastic system that you've put together. I've currently got an M5stack board with a temp sensor attached running in my son's room; the board is great as it has a screen and a few buttons included, but I'd love to expand its functionality and have more sensors and switches running from it. I need to make it look nice so I can wall mount it too.

[@YaroslavHeriatovych]

OMG. That project is amazing. Just less than a couple of months ago I was evaluating options to manage all the relays and inputs for a future home projects. I was surprised by the lack of options. Either there were enterprise PLCs costing thousands of dollars and requiring proprietary soft to configure or just simple DIY devices a-la simple relay board connected to raspberry pi via Arduino. And most of those devices are not even din-rail mountable! Additionally to that, I'm really addicted to esphome. The ability to program simple local automation but leave connectivity for home assistant is a blessing. Looking at your hub, I feel that it checks all the boxes I was looking for. Amazing work, cannot wait to build or buy that.

[@SmartSolutionsForHome]

Thanks!!! :) If you will build it yourself and have any questions, feel free to write to me, I'll be happy to help :)

[@YaroslavHeriatovych]

@@SmartSolutionsForHome Sure I will :) What is your experience with such compact placement of SSRs? Do you use them directly to power appliances or use them to switch external relays? If you power appliances via SSRs directly, is heat dissipation good enough?

Wanted to do the same but waiting for MATTER to be completed and generally I prefer inbox controls like Shelly's. But if you don't like any switches in the walls - your solution is the way to go. [Also makes me think of so many stupid custom hacked commercial installs with PLC's and a proprietary software + no din mounting]. Thank you for sharing.

Regarding the wiring colour scheme, just sleeve the wires with brown sleeving to make it compliant. (Or whichever colour matches the phase you're using.)

[@SmartSolutionsForHome]

Thanks for the tip. I considered it, but... I didn't feel like doing it :P Assembly took me long, long hours. I had a bit of enough already.

@@SmartSolutionsForHome You can use just some isolation tape to indicate live wires + maybe brother laber maker to label them as "fazowy\live\hot" :D And yeah, Brother label maker, because Dyno paper now have DRM, so you need to buy paper from them on newer machines ^^

[@SherifMalek]

Woow great work... That is really impressive and inspiring at the same time. I just had a few questions... 1. Do you have any ideas/methods of handling dimmer lights using this hub? 2. Any recommendations on how to handle automatic rolling shutters and motorized curtains? 3. Any ideas on how to handle regular RGB/RGBW led strips or even addressable ones? 4. Can you please elaborate more on how the RJ45 sockets work with inputs? 5. What are the maximum safe load ratings for this solution (Amps/watts) per relay circuit? But man... I have to say... You're inspiring, keep up the great work, and amazing video quality. 👍🏼 Can't wait for your next video.

[@SmartSolutionsForHome]

Thanks! :) 1. I'm working on it. 2. It depends on the motor of the roller shutters. But usually 3 wires are enough for this purpose. 3. In general, how would my HUB do this? Currently HUB cannot do it, but I want to make another module especially for RGB LEDs. 4. Its just a connector. It's the easiest way to connect the Ethernet cables to the HUB. 5. 2A per circuit.

Nothing can be planned, neither the final price nor the completion date. And I would not like to disappoint anyone, so I won't do it at all, for now.

[@hikingpete]

I loved the build. A little bit of edge trim around the hole in the cover could clean that up nicely.

You are right, of course. I was in a bit of a hurry, hence such inaccuracies. Maybe I'll cut the plexi on the CNC, it'll be quite perfect then :) I'll show it on the community card if I manage to do it.

[@bharathduraiswamy7429]

Firstly mind boggling 🔥. I do have few queries though. 1. Is this way of writing schematic (directing all appliance lines to single location inside the house) is the norm in your country? 2. Do you provide separate routing of lan cables from ac wires behind the wall? 3. How do you intend to use inductive loads now (fan, electric herd, iron box,...) since you seen to be using SSR? But a great leap altogether. Cheers 😎

[@SmartSolutionsForHome]

Thank you! :) 1. No it's not. You will never meet anything like this in classic installations. However, it becomes more and more popular if the "smart" installation is planned already at the design stage. 2. Yes 3. I'm able to handle the inductive loads. If the SSR has a built-in "snubber circuit", it can easily handle this kind of load.

[@jodysaliba]

@@SmartSolutionsForHome to piggyback off the original question, what are you using at the load-end of the circuit for plugs, etc? These SSRs are only rated for 2A, so I find it hard to imagine using this for anything more than LED lighting.

[@MrGirgitt]

I did something similar 10+ years ago. Actually couple automation islands like this interconnected with a ring rs-485 bus. Since the creation of ESP8266 such a setup makes no sense at all in a home environment. It is much quicker and cheaper to use local control loops using Shelly actuators (dimmers, relays etc.) and deploy redundant Wi-Fi network (two routers with mosquito mqtt brokers and virtual ip failover using vrrp/keepalived). Such decentralized setup is relatively inexpensive and reliable as it has no single points of failure regarding direct control (e.g. switch to light bulb). You can even live without the Wi-Fi redundancy - in case of failure / downtime / upgrade you lighting still works. Every married man should understand the benefits here.

@@SmartSolutionsForHome my dream is to build my own house in the near future and have something like this in it but had not found a solution yet This sure checks a lot of boxes :) The problem now with my HA is that it’s mostly wireless stuff and it works good but there are still moments that lights won’t switch directly due to interference and I also want the possibility that if Home Assistant has an issue and is offline or something that the basic lighting still can function, and this can make that happen. In my current house it’s not doable to achieve this but in a future house it absolutely is.

Hello Sebastian. Recently I got a Raspberry PI as a gift from my girlfriend and I started to do some researches about what can I do with it. I ran into your channel and your content was really entertaining and inspirational for me. But since I'm a complete newbie in this field, I got confused at some parts. So I wanted to ask a few questions if you don't mind. 1. Would it be possible to expand the number of GPIO's using multiplexers? I'm imagining something like this - Add for example TCA9548A multiplexer to the main board which would give me 8 separate I2C channels where I can use the MCP23017 chips. 2. Is 12V enough even for a larger house or would you recommend 24V? 3. Are you maybe planning some additional modules for dimming lights or some LED module? 4. Are you planning on making the part 2 of integration with HA? And once again, good job!

So this is just like the SuperhouseTV system that he designed and built about 4 years ago. Good to have options, and it look like you have pretty decent integration.

[@SmartSolutionsForHome]

I don't know the SuperhouseTV's system. But I'll be glad to learn about it. Do you have a link to a specific video? There are a lot of them on his channel, and I don't know which one to watch.

[@DodgyBrothersEngineering]

@@SmartSolutionsForHome the two I would start with are "SuperHouse #24: Home automation system architecture" and "SuperHouse #25: Rack mount Arduino / MQTT light switch controller for home automation" from 2017. That was the first iteration of the system, it has now developed into so much more. The first version of the light switch controller, spawned a lot of discussion over on the Discord server, and that developed into a second version of it using I2C, which expanded the I/O possibilities. Then some very smart software people started getting involved (I was doing my own software version at the time, because I was trying to achieve something slightly different) and the idea of it just controlling lights expanded into other things like door switches, etc etc. The software kept developing to incorporate new switch types and sensors to the point it is now quite a robust system to work with the open source hardware SuperHouseTV developed. Several people have developed similar ideas but Jon's (SuperhouseTV) is the most complete I have seen. It is designed in such a way that you can use any front end you want. So if you prefer Home Assistant over OpenHAB then you can choose the interface you prefer. The system is capable of talking to virtually any device that uses MQTT to pass messages. As the idea grew other people started to build their own add-ons to the system, so the hardware side of things has plenty of options. The system is now called "The Open eXtensible Rack System", and if you do a search for OXRS Docs you will find out what the project is all about.

[@haiyanghuang2425]

I'm very glad to see such excellent works. I have always had similar ideas, but I don't know how to realize them. I really want to have it, but now the chip is too expensive, and I'm afraid to step back. There is another question. Is this drawn using easy EDA? It would be great if you can change the chip package yourself, because dip28 is relatively cheaper.👍👍👍

[@Adrian-sw3nv]

To start, wow, this is involved and some amazing work! I’m new to HA, and have been looking for a reliable way to control lights/sensors but have a few questions; 1) are your light runs going from the breaker panel to the smart hub then to the light socket or to the light switch? 2) what switches are you using? They have Ethernet ports? Sorry if they are rudimentary questions, but I’m just getting into the smart home scene and I really don’t like the idea of light switches relying on wifi and things like that. Thank you!

[@SmartSolutionsForHome]

Thank you! Your questions are definitely not rudimentary! 1. Exactly: Breaker panel -> HUB -> Light. 2. I use ordinary mechanical switches.

So basically everything that gets powered from mains passes through here first? I am not familiar with European electrical, but I am trying to wrap my head around it. Here in the States, I have 240A@200A service to my home, the 240V is split to two legs 120V each (220v -> 110v nominal). Each room in the house is one one or more 15A or 20A breaker. How are you powering everything off from one breaker?

[@user-zn8mi2rc7h]

In Poland for example in most of the houses we have 3 phases one neutral and ground wire, so 4 wires are coming from the grid, grounding you need to do it on your own. So on three phases we have around 400V. On the movie he did not used a breaker he was using something what is called switch disconnector, so he just disconnet all three phases.

[@Fine_i_set_the_handle]

Very cool project and extremely reliable design, I'm surprised a single esp32 running esphome could run that much I/O, unfortunately it sacrifices alot of features like dimming, kelvin coloring and rgb coloring on the lights. I would like to build a scaled down version for sensor inputs doors/windows and maybe motion.

[@SmartSolutionsForHome]

Thanks, In this project, I didn't actually envisage more advanced light control options, but.. it can be done. Many pins of this ESP32 module are unused. So it's possible to add support for dimming, color temperature or full RGB. Of course, it would require a design modification, but it's feasible :)

Thanks! The previous version was also OK, but this one is a whole different animal :) As for the cost, it's hard to say. I already had a lot of these components, so I didn't have to buy them. And I bought them a long time ago, while the prices were still "normal". A lot also depends on what power supply option you choose and how many INPUTS / OUTPUTS you need. But if I'd had to estimate (very roughly), I would say about $100 for one module.

[@sotoskal3201]

Awesome project ! Is the follow up video coming soon ? Can`t wait !

[@SmartSolutionsForHome]

I'm glad you like it! I'll definitely make a follow-up, but I can't say exactly when.

[@SparkyJames]

Thats some impressive compact wiring!!

[@SmartSolutionsForHome]

Thanks!! :)

[@Nils_1984]

impressive, i would want to do this my self, - i guess in my next life. no time. in this life

[@cooperised]

Fantastic project! Would love to see the ability to use some outputs as dimmers... 😁

[@SmartSolutionsForHome]

I'm gonna tell you in secret (just don't tell anyone :) ) I'm designing a mod with a PCA9685 chip, which is perfect as a dimmer :)

[@cooperised]

@@SmartSolutionsForHome Amazing! :-) Can you combine it with the zero crossing detection to do trailing-edge mains dimming somehow?

[@jean-baptistetetia6487]

Very good job, don't see big production on start. But In Europ there is some solution for start little. I can help you if you want.

[@Claudio-fm2xo]

Great Work, just one question: why didn't use internal pull up resistors from MCP ?

[@SmartSolutionsForHome]

Great question. I was considering using the internal pull-up, but it's quite weak (100kohm). And since I wanted a steeper slope, I preferred to use an external one with lower resistance.

[@ЕгорСмоленский-х8х]

Wow! This so cool. Thanks a lot, try to do that!

[@haldir234]

Love the idea. great video i have somthing similar in my pipeline. In few years..

[@dharmapatel2235]

Hello amazing work, do you have anything for dimmable and tunable CCT lights?

[@andyburns]

Your attitude is similar to mine ... wires are always better than radio, local control is always better than the cloud.

[@SmartSolutionsForHome]

100%! In terms of reliability, the wires always win :)

[@rak3shpai]

Hey. What protocol do you use on the ethernet wires to the end devices? Are you using full-on ethernet? Or are you using the wires just to carry power and signals? If it's the latter, how do you deal with issues like interference?

[@SmartSolutionsForHome]

Hey, I use it to carry power and signals. At such super-low frequencies and the voltage of 12V that I use in these cables. The interference issue doesn't occur. In addition, I didn't lay them very close to the mains cables. Ps. a fantastic, insightful question. I like such :)

[@rak3shpai]

@@SmartSolutionsForHome Thanks for the reply. Really impressed with your work and the quality of your videos. Looking forward to the next one. Would be great if you could also share some examples of stuff at the other end of the cat6 cable. Curious to see how you're using the cable.

[@rak3shpai]

Just a reminder: Haven't forgotten about this. Looking forward to a follow-up video.

[@jefcarlier9067]

cant wait for the home assistant video

[@MarcioTorres]

Congratulations, an excellent job. And best of all an open source project. I would very much appreciate a group that is not on Facebook. I don't understand why the proxy at the company I work for blocks access to you website. When I'm home I'll visit your website and your store. Thank you and success always.

[@SmartSolutionsForHome]

Unfortunately, I don't use any other social media myself. There's always KZbin :)

[@silverlex1]

Amazing! I’d also be interested in being able to buy this as a commercial product!

[@SmartSolutionsForHome]

Thank you. And as for commercialization.. maybe one day! The market for electronic components is too volatile. For now, I'm selling only PCBs.

[@csgrullon]

@@SmartSolutionsForHome you could do a kickstarter campaign for funding and have a few thousand pf these made after you have ironed out the issues with the initial design. I would buy one and i know many more folks would do so as well.

[@jawadikram5989]

Absolute legend. Nice one

[@popsyann]

Excellent work! Bravo.

[@Vic-sp6ld]

Just to be sure... Is every power socket, every switch, every point of light routed to your distribution board? Thanks in advance

[@saadalshahranni7117]

you do it perfect....go on👍

[@treynolen]

This is very nice and your skillset is awesome. What kind of job do you have? I need something like it so I can have this much spare time!

[@SmartSolutionsForHome]

Thank you. On daily basis I'm software embedded engineer.

[@D-Khaz]

Nice build! I’ve designed something similar but the lack of supply of MCPs is pretty painful…

[@SmartSolutionsForHome]

Tell me about it.. You don't want to know where I got these chips from :P

[@lukagodnic]

Great project, thank you for sharing. I implemented similar idea with PCF8575s, but sometimes are not so reliable so I plan to migrate to MCPs but it takes forever to get them... Have you encountered the limit of entities in ESPHome? When having over approx 75 entities (inputs or outputs doesn't matter) on one esp32 esphome started to behave weirdly to me...

[@SmartSolutionsForHome]

I understand you perfectly.. Currently, the purchase of MCPxx is almost a miracle. Not to mention the price from outer space.. As for the ESPHome: currently I've 64 binary sensors and 64 switches for MCP23017 chips, 1 binary sensor for Mains detecting and LED RGB. So currently I use 130 entities. And I don't have the slightest problem with stability. Maybe it's because I'm using the Ethernet port and not WiFi?

[@dansilful]

Great project! Maybe I am missing something but please explain further, how you connect sensors and light to your central location. Are you using analog sensors or what protocol? What about distance limitations? Thanks!

[@gdave44]

If I understood correct, and remember correctly from my time in Germany; Most light switches are low voltage that flip a relay in the power panel to activate the light. Thus, making a centralized solution like this much easier to achieve. In the US, light switches pass mains power through them to the light. Centralizing that would be much more difficult and expensive.

[@dansilful]

@@gdave44 yeah ok I get it for the lights. Although I might have my doubts that the 3.3v give accurate results for a switch e.g. in the attic. BUT I think he said that he connected the switches to mains to have offline control? Anyhow sensors are a topic to talk about I guess. I also couldn’t find something on the website

[@gdave44]

@@dansilful it's been a while, so my memory may be a bit foggy on the details. But I built an ESP32 based hub for my wired alarm system a few years back. I put either 12v or 5v into it, and then run it through a resistor before coming back into the GPIO. That ensures the resistance of the wire doesn't keep the signal from getting back but also doesn't overwhelm the GPIO.

[@SmartSolutionsForHome]

@dansilful I use 12V for all wall switches. And you're right, 3.3V would be extremely unreliable.

[@pepo543]

👍🏻👍🏻👍🏻 hi, are you planning to make a video about home assistant and esphome?

[@andrewlhoover]

Nice work! Good iteration in that your 2.0 is cleaner and more modular! Very nice! Was a reason for this upgrade the relatively recent removal of local GPIO support in home assistant?

[@SmartSolutionsForHome]

Thanks! There were several reasons, but it was overwhelmed by bitterness. In the previous video on my channel I mentioned all these reasons, and GPIO support is one of them.

[@andrewlhoover]

@@SmartSolutionsForHome I will definitely watch those for the context. Again, excellent work.

[@GaryBarclay]

Very cool hub, what happened to the followup video?
