Simple and good roller shutter control

: Do you have a solution to control Somfy io with third-party components?

Somfy io is proprietary, as far as I know that’s not possible. (Unless you solder onto paired remote controls)

There are gateways like RFlink, for example.

But I would do it anyway with KNX because it is wired and robust, maybe not the cheapest. But if you’re into Shellys etc., you can find solutions there too, though you have to tinker. KNX is the no-brainer here.

Maybe take a look at Loxone sometime. They also offer wireless retrofit solutions (Shading actuator) or wired control options. With the Miniserver + possibly a weather station (if using blinds), you can quickly and easily create logic. Maybe download the Loxone demo app briefly to get a feel for it.
