Neither the Tahoma app nor the Somfy RTS app seems to be capable of adding a Somfy switch so that I can use it as a trigger in a flow. I would like to trigger KaKu sunscreen switches that operate my Goelst electric curtains with a Somfy Open/Close RTS switch rather than by a Kaku switch.

Somfy RTS switches transmit on a frequency that homey can not listen on. Therefore it will not be possible to add them directly.  
I use an RFLink module connected to a Raspberry Pi running Domoticz to listen for the switches. . That connects with homey via MQTT so homey can respond via flows.  
My aim is to keep the curtains / blinds state synchronised.
