I installed outdoor Venetian blinds in my new home in Czechia (EU), using Somfy IO motors and connecting it to Tahoma Switch hub. The main problem I have with the integration and solutions found here is that IO motors aren’t the same in US (that radio is used by police I think) and the TaHoma Switch is quite new so no handlers are made now (only for older TaHoma and Connexoon, which have been working with now discontinued SmartThings Classic app).
When talking to Somfy technician, he suggested plugging a USB ZWave stick to the Switch to make it ZWave hub and connect to it, but I don’t know if it would work also in the opposite direction, i.e. connecting Switch to ST hub (Aeotec v3) and through that all the blinds.
I’m certain there are many people looking for a solution as Covid made everyone invest in their homes rather than traveling and I don’t think it is impossible to make it work for French company in EU.
