Sonoff-Somfy-HomeAssistant

This project describes a simple way on how to use a Somfy remote control with a Sonoff 4CH Pro.

Somfy Telis 1

For this project the Somfy Telis 1 Pure RTS, 1 Channel remote control was used.

Soldering

3 switches - UP / MY / DOWN

This is how it looks like after putting some shrink-on tube on it.

Sonoff 4CH Pro

The Sonoff 4CH Pro has been flashed with Tasmota firmware using SonOTA.

Please see the wiki for known working configurations.

The Somfy remote fits exactly into the Sonoff case and there is still enough space for the cables.

• R1 - unused
• R2 - UP
• R3 - MY
• R4 - DOWN

MQTT

After flashing Sonoff with Tasmota firmware it is possible to control it using MQTT and therefore easily integrate it into HomeAssistant. There is also a Mosquito broker add-on available for hass.io.

HomeAssistant

Sample configuration.
