As far as I know, it is the same, but the suppliers use different names. When setting up, it is important to use the "TaHoma by Somfy" app on iOS. The yellow one with the white house icon. Then it works very easily with the connection. My RTS blinds are now running on the app and also in the Home Assistant with the "Overkiz" integration.

Yes, exactly. Runs smoothly for me.

the difference is how they connect to the internet, one is fully WIFI and the other RJ45
