Make your Somfy-RTS-remote smart using an ESP8266 and MQTT to control your awning or shutters

[@MakerMeik]

Down in the comments you'll find the findings of user Darren Cotterill. He has forked the Github project to add the ability to replace multiple remote controls: github.com/DCotterill/Somfy_Remote/ He also describes in his comment what to do if the pairing doesn't work right away: "As a tip for others, I did have trouble pairing with the blind initially, so I 'reset' the pairing on the blind by holding the reset button on the motor for 15 seconds (3 sets of jog up/downs), then re-pairing my remote, then pairing the MCU." [If necessary, you will need to "full reset"], but be aware it will clear all your blind settings so you’ll also need to re-pair your remote and set limits again." Thank you, Darren, for your contribution to the community. By the way, Nickduino, the original developer of the project, also has a Raspberry Pi-based project for the Somfy remote controls on his Github page: github.com/Nickduino/Pi-Somfy

I came across your video while searching for a replacement for Somfy’s “MyLink” automation solution. After 3 years of frustration using Somfy’s expensive, buggy and amateur MyLink app and their 20’-30’ range transmitters to control the 21 blinds around our house, I found (and now use daily) the Bond Home WiFi bridge that achieves the same goals as your project….for those of us who lack the technical skills needed to implement your project.

[@gadjetsvideo]

We cross paths again, first it was the wireless window sensor and now you help me again with Somfy remote controls, thanks for the really useful video........ Again

[@MakerMeik]

That's really funny. Actually, I've also been on your website several times in the last few days (www.gadjet.co.uk/) and have been looking intensively at your optimised version of the window sensor. I am working on a video about it. You can see that our paths are crossing again for my part as well :-) So there is also something nice about the fact that the "endless summer" is now over and there is finally time for tinkering again.

[@Torsan1977]

Nice work! Thanks for sharing.

[@conlethoc]

Strange, as per another poster, my comments disappeared. I'll try again. Absolutely genius! Loved this. Have used this on my garage door and integrated with home assistant and alexa. Great stuff!

[@MakerMeik]

Thank you! And also for taking the trouble to write the comment again. I had already seen your comment in the email announcement and appreciated it. Unfortunately, there still seems to be a problem with KZbin and this post was deleted again. I wonder if it's the feature to automatically withhold potentially inappropriate content. But even then, I should be able to find it in my account under "review pending", but so far that has happened very rarely. Anyway, I've disabled the feature now and hope that future comments will arrive. In the email announcement to your original post, I saw that you also had problems with AsyncElegantOTA. I have now looked into this matter again: Other than shown in the video, you need the libraries ESPAsyncTCP and ESPAsyncWebServer from me-no-dev on Github in order to get the OTA update working. Unfortunately I had forgotten about this. You will not find them in the Arduino IDE Library Manager, but you have to download them directly from the Github page and put them in the library folder of the Arduino IDE: github.com/me-no-dev/ESPAsyncTCP github.com/me-no-dev/ESPAsyncWebServer I have now also added this comment to my code on Github, so hopefully future viewers will have it a bit easier. Anyway, the OTA update feature is extremely handy. Rui Santos, for example, recently made a good video about it: kzbin.info/www/bejne/gobGfKKAfL1mbq8

How did you manage that the devices are displayed in Homeassistant?

[@DCotterill]

Thanks very much for this. I've just installed new Somfy blinds and just managed to get one working with this code. Now I just need to change the code to get it working with multiple blinds / groups, as I have 15 blinds over 6 rooms, using 4 remotes with 5 channels each :-) As a tip for others, I did have trouble pairing with the blind initially, so I 'reset' the pairing on the blind by holding the reset button on the motor for 15 seconds (3 sets of jog up/downs), then re-pairing my remote, then pairing the MCU.

[@lepetitponey]

What do you mean by "having trouble pairing with the blind initially" ? Program mode on your remote -> blind jog -> program mode on MCU -> nothing happens ? I have this exact same problem, except I'm using the python version on a raspberry pi (github.com/Nickduino/Pi-Somfy). I thought I messed up with the crystal soldering part, but maybe I'm gonna try what you suggest.

[@DCotterill]

@@lepetitponey yes, this situation exactly. Give a ‘full reset’ a try as I mentioned, but be aware it will clear all your blind settings so you’ll also need to re-pair your remote and set limits again.

[@dennis-q4618]

@@DCotterill If the the virtual remote was programmed with an incorrect rolling code or there is a mismatch then the motor wil ignore it (can not pair or unpair). This is why it is important to keep the remote id and rolling code safe in case you need to rebuild something.

[@lepetitponey]

@@DCotterill I tried resetting the receiver next to my motor, but I don't even know if I did it right, we probably don't have the same model. Anyway, that didn't make it work. It turned out I did a bad job on the soldering. I just soldered another crystal on another emitter, and now it works just fine. I'm glad I bought some spare ones.

[@DCotterill]

@@lepetitponey Great to you managed to get it working. Those crystals are a little fiddly to solder in, I wasn't sure I'd done it correctly myself either.

Hi MekerMeik. I am looking for the same ESP8266 that you mentioned in the beggining of the video but I am not being able to find it. I didn't find the D1 Mini ESP-12F. I was able to find D1 Mini V3.0.0, D1 Mini 4.0.0, D1 Mini Pro4M, D1 Mini Pro 16M, D1 Mini Type-C. Do you know if it can work with this other ones as well? I have 8 Somfy blinds at home and my plan is to use the branch that Darren Cotterill created to make that happen and then control it using the HomeAssistant with Mosquitto.

[@mic03311]

Thanks for this great video! How did you figure out that you needed to change the resonator crystal and how did you pick the right one? Please keep up your great content, it is great stuff!

[@MakerMeik]

Thank you very much. 😊 Here is documented how the reverse engineering was done: pushstack.wordpress.com/2014/04/14/reversing-somfy-rts/ However, it wasn't me who did that, I just enjoyed the already finished project from Nickduino and modified it to suit my needs. I think as a general approach this should also work via Software Defined Radio (SDR). There is a good video by Andreas Spiess on this topic as well: kzbin.info/www/bejne/roK5nmCPibCFb9U Andreas also has a video on 433 MHz remotes: kzbin.info/www/bejne/gmHJhHiYfKqMY7M Unfortunately he did not cover the Somfy remote controls. So I ended up with the project and ultimately the video for my own purpose.

Hallo meik, klasse Videos, habe deinen Door sensor v5 pcb produzieren lassen allerdings mit espnow -> mqtt statt wifi -> mqtt, echt klasse. Nun meine frage: Mein Vater hat einen Sompfy Rolladen Motor und eine nicht sehr stabile Fliegentür welcher er im Sommer zur Terrasse benutzt. Wenn jetzt versehentlich (oder abends automatisch) der Rollo runterfahren würde und die Fliegentür noch auf wäre, würde diese zerstört werden. Als Workaround habe ich einen Offner installiert, der die Stromverbindung zum Motor unterbricht wenn das Fliegengitter offen ist, klappt soweit, allerdings gibt es wenn die tür zufällt (motor also wieder Strom hat) die im Video gezeigten hoch runter Bewegungen, das ist nicht ganz so schlimm, manchmal aber auch bis in Brusthöhe welches einen faktisch aussperrt. Ich vermutete den Programmiermodus und baute eine Verzögerung ein, so dass dieser nicht mehr erreicht wird (2 sek an 7 aus ...) das brachte auch nix. Meine neue Idee: Einen Sompfy Receiver zu benutzen (RX-4M30RR01SF) und einen Strom Sensor. Wenn der Rollo autorisiert Strom zieht (Empfänger hat ein Signal empfangen) wird nix unternommen. Wenn er aber ohne per Funk autorisiert Strom zieht (also das seltsame verhalten zeigt) wird der Strom zum Motor unterbrochen. Jetzt ist nur die frage, ob die zentrale nicht für das hoch runter verhalten verantwortlich ist. aber anhand was genau empfangen wurde "hoch" "runter" "init" sollte sich das unterscheiden lassen. Weist du ob die Funkpakete verschlüsselt sind bzw. entschlüsselt werden können damit ich auch weiß dass das richtige Gerät angesprochen wurde? Ist dir mal ein ähnliches verhalten aufgefallen? Hättest du noch andere Ideen? Wie würdest du versuchen das Problem zu lösen? Notfall müsste ein anderer Motor her, Papa wollte aber bei Sompfy bleiben. Ich hatte schon überlegt den Empfänger des Motors stillzulegen wenn die Tür auf ist, will mein Vater aber verständlicherweise nicht und ich glaube auch nicht, das dass was ändern würde. P.s: Als ich zum basteln eine Fernbedienung gesucht habe, habe ich gesehen, dass die Taster die mein Vater benutzt 868 mhz (Somfy Smoove) demnach auch ein evtl verschlüsseltes protokoll, mein homatic jedenfalls ist versch..., hoffentlich komme ich trotzdem weiter der 433 mhz receiver zu bestellen, war schonmal zu voreilig :( Vielleicht hast du ja noch ideen. bist du auch auf der makerfaire? dann kannst du uns besuchen (Hackerspace bremen e.v)

[@pascalbeyer2485]

Wahsinnig gut! Ich habe es auf meinem ESP8266 am laufen. Jetzt habe ich nur eine Herausforderung die ich nicht hinbekomme. Ich möchte es in Homeassistant nutzen, wie bekomme ich sowas hin? Weiß nicht ob du mir dabei helfen kannst.

[@IdioticUsername]

Thank you so much for this! We always misplace the remote and have to run around and search for it. Now I have the awning integrated in Home Assistant and it works beautifully! BUT I also have the sun and wind sensor, and there is a button on my remote that toggles it on and off by long pressing that button. Do you by chance know what command I should use to trigger the toggle? I tried sending 0x9 but nothing happened. Thank you so much!

[@maartenkoks]

Nothing happens after uploading the sketch? What can be the problem? I am pretty sure I did everything wright. Compiling and uploading is all fine, but nothing apears in the serial monitor?

[@MakerMeik]

Have you tried another D1 mini? The serial.prints should appear in the Serial Monitor regardless of whether the radio data is being sent. So I guess that there is a problem with the D1 mini.

[@sledgeHammerRulez]

Hi ... great minds think alike! I was planning the same conversion of the nickduino code but also with a position parameter (in %, based on the time it takes to go out and in) and 3 buttons on the case (in stead of the remote). Maybe I will implement the position in the home-assistant (custom) control (like I did for my shutters). Have you any idea if there is already a Python-Raspberry Pi version of this control? That would suit me even better (since there is a pi with home-assistant laying next to the awning ...

[@MakerMeik]

Hi, Sure, there is even a Python version of Nickduino itself, which is intended for the Raspberry Pi. Best you have a look at it yourself: github.com/Nickduino/Pi-Somfy

[@dennis-q4618]

Yes this already exists: github.com/Nickduino/Pi-Somfy

[@amonmakesoriginalnoises]

Would the Raspberry Pi + 433 transmitter suffice for making the somfy blinds work with a Broadlink RM4?

[@tis4real]

Hello, thanks a lot for your share! I managed to make it work but shortly after the crystal stopped working and after several attempts (soldering of several crystals) I managed to make it work again and the crystal stopped working again. Currently unable to operate the device. Could it be a soldering temperature problem? What is the best temperature? I'm a bit lost (I'm more than 10 tries).

[@MakerMeik]

I usually solder at 350°C. The soldering iron should remain for about three seconds per solder joint, then you should not have any problems. I wonder if maybe your transmitter has problems with the 5V voltage or a short circuit somewhere? Instead of changing the crystals you could try it again with another transmitter. What makes you so sure that it is the crystal? An if you have connected everything only with jumper cables, it can often come to loose contacts. Since the problem you describe did not occur with me, I can only guess.

Hello MakerMeik, I have build all how you explained in your video, but my awning is not responded to the commands through the MQTT dashboard, I get this in my serial output from the Arduino: p p p prog Frame : A7 80 64 84 12 13 05 With checksum : A7 8F 64 84 12 13 05 Obfuscated : A7 28 4C C8 DA C9 CC Rolling Code : 1647404164 prog mode is that rolling Code good? Or is this output complete, not good? Can you advise me please? Further great video's !! I like your videos best regards, Mark

[@MakerMeik]

This is difficult to solve remotely. Did you follow all the steps in the video? First of all, you should make sure that your MQTT commands arrive correctly. For debugging, you can put some 'Serial.print("bla bla");' in the appropriate places in the code and check in the Serial Monitor if they are executed. Next you have to do the steps I described from minute 8:30 (kzbin.info/www/bejne/b4PLeaWPptVsfLc). So press the "Program" button on the original remote control and then execute the "Program" function of the ESP. Then your awning should already move. As I have stated, however, this only works with the RTS-remotes. Somfy now also sells the io series, which is not compatible with the described procedure.

@@MakerMeik Ich dachte mir das schon, bisherige Ansätze führten immer dazu eine originale io-Fernbedienung zu nehmen und die switches abzugreifen mit Relays.

Hello MakerMeik, after pairing the MCU with the awning, can you still use the remote?

[@MakerMeik]

Yes, that is not a problem. You can even use several MCUs or remote controls in parallel.

[@DonParlor]

@@MakerMeik Wow! I was not expecting you to answer this fast! Thanks! I have a dilemma between going with a ESP8266 MCU with your tutorial or building a RFLink gateway with a nodo-shop kit. I could use HomeAssistant natively and they seem to integrate drivers already. Have you considered this option that is fairly cheap or you looked for the cheapest option possible?

[@MakerMeik]

Unfortunately, I am not familiar with RFLink gateways and the Nodo Shop Kit. The ESP8266 variant was directly feasible for me because I had all the components apart from the quartz and they were extremely cheap. The solution works reliably, so I will probably not test any other options. If you go the other way, I would be happy if you share your experiences here with me and the other readers.

Apparently, the error is due to AsyncElegantOTA. Check if you really have the latest version installed. github.com/ayushsharma82/AsyncElegantOTA Also the ESP8266 core in the board manager must be up to date. If you use PlatformIO with VScode, you should check if the error also occurs via Arduino IDE. I think I remember that there was a problem with PlatformIO once.

Hmm ... did you check if the file "AsyncElegantOTA.h" exists in the mentioned directory? If not, providing the files in that directory is certainly the fastest way. If you don't know where it ended up by installing the library, you can download it again here in case of need: www.arduino.cc/reference//en/libraries/asyncelegantota/ If you want to get to the bottom of it, you can also read here how the library manager of the Arduino IDE actually works. www.arduino.cc/en/guide/libraries But in the future I would recommend to switch from the Arduino IDE to VS Code with PlatformIO. This offers many advantages and is easier in the long run. However, from my point of view, getting started is a bit more difficult, which is why I limit myself to the Arduino IDE in my videos.

[@chrisearlyup]

@@MakerMeik Thanks a lot for the advice. I managed to get the code working using VSCode and pulling the libraries as needed. no idea why it didn't work using the Arduino IDE.. Now i just have to wait for my crystal to arrive. Lets see how customs work out. Just another quick question: i have the same setup as you do wit the wemos d1 mini and the same pinout printed on the transmitting board. Is there any reason you connected vcc to the d1 pin and not to the 5v pin. Logic dictates to me vcc → 5v; GND → G and Middle Pin → D1. (Transmitter Board → Wemos D1 mini). Am I missing something here? Keep up the good work. Maybe you’ll become the next “youtuber with the german accent” ;-)

[@MakerMeik]

Hi Christian, unfortunately the transmitter boards are printed a bit unfortunate. If you have a closer look, you will notice that the left pin is marked as ATAD, the middle pin as VCC and the right pin as GND. Unfortunately, at first glance you might think that VCC is on the left pin. But what is meant is the middle pin. I hope that was not too confusing. ;-)
