This ESP8266-based controller allows to remotely steer the Sommer Pro+ Garage door control.
It connects to an MQTT broker and listens on one topic <device-name>/command to steer the garage door and updates it state in real-time at <device-name>/isClosed. In my case I use IOBroker MQTT adapter in server mode as broker, but it also works with Mosquito and such.
Use at your own risk!
Things needed to run this:
- A Sommer Garage Door Pro+ Control (looks similar to the icon at the top)
- Sommer Conex (S10807-00001)
- Sommer Relay (7042V000)
- the assembled board and all parts listed for it
- some spare electrical wires to connect everything
- A MQTT-broker installed somewhere in your network which the board can connect to.
It might work for different components as well, but this resembles roughly my setup.
- Micropython firmware needs to be flashed to the esp8266-board first. Can be done with
esptoolor uPyCraft editor (or similar).- This code requires to python libs (mqtt_as.py & sdcard.py) to be frozen into the firmware as the board has not enough RAM to compile it during runtime, so installing just the esp8266 port of micropython won't work
- Options:
- Include the two libs in the modules folder of the MicroPython ESP8266 port and build it yourself. Getting the build to succeed might take some work though Flash the
firmware.bin. - Take a firmware I built for myself and flash it to your device at your own risk! (based on v1.22.2)
- Include the two libs in the modules folder of the MicroPython ESP8266 port and build it yourself. Getting the build to succeed might take some work though Flash the
- The files from the
srcfolder need to be copied to your board. This can be done easily via editors like UPyCraft or CLI tools like ampy. Be sure to renameconfig.json.tmpltoconfig.jsonand setup your config credentials correctly.
| Topic | Values | Description |
|---|---|---|
<device-name>/command |
open, close |
Trigger the door to open/close. |
<device-name>/isClosed |
true, false |
Current status of the door. |
<device-name>/lastUpdate |
Timestamp when door status was last checked |
Please refer to the board design description for more information about the board. This repo contains all files required to print/assemble it yourself.
- Sommer in their online document-library provide a set of instructions on how to connect the garage door control to Somfy's Tahoma box: https://downloads.sommer.eu/files/Anbindung-base+pro+anSomfyTahomaBoxRaccordementdebase+pro+laSomfyTahomaBox_S12360-00000.pdf. However there are (from my perspective) some issues with it.
- Somfy GU Controller io Art. No. 1841211 is required, which is a) very expensive and b) hardly available, as apparently Somfy stopped manifacturing it (for unknown reason)
- You also need the Somfy Tahoma box ($$$) to make any use of it
- There is a custom-built solution based on Arduino described/sold here: https://arduino-projekte.info/homekit-garagentor-und-drehtoroeffner-eps8266-arduino-hoermann-sommer-antriebe/
- Although quite cool, it offers no integration with Sommer Relay (Art. 7042V000), only with Sommer Connex (Art. S10807-00001), meaning you can steer the garage door, but will not know if it actually is opened or closed.
- Software-wise it integrates directly with Homekit (Apple Smarthome), making it unusable for my smarthome setup.
