Before I go out and buy a Homey professional I would like to be sure that it works flawlessly to steer blinders that contain the receiver from Somfy a French Smart Home provider. Has someone tested it?

I think it depends on the protocol: Somfy RTS devices can be controlled by Homey. At home our sunblind works nice w it. I think w/ RTS it’s a matter of distance as it’s radio frequency is pretty weak (correct me if I’m wrong).

If I get you right you do steer Somfy RTS sun-blinders with Athom Homey - I’m insisting because I once bought a multipurpose home automation device but it didn’t work. The radio frequency (433 MHz if I’m right …) was there but it seems there is a specific communication protocol and this was missing. …

I use the Somfy RTS app by Matthew Wanders to control my curtains and indoor roller and venetian blinds. Homey has the built in radio to control these directly but there’s no feedback (send communication only). If you use the remote control to open or close the cover then Homey will not know. I use…

IO with tahoma is better as it gives feedback on the status of the somfy devices and not that much negative reports. but expensive. I have fibaro rollershutter 2 with somfy sonesse 40 WT (no RTS, just wires, 230v lift & tilt) should work ok, haven’t tested it yet as i get the horizontal blinds end…

I have IO shutters, IO solar sensors and IO temperature sensor connected through TaHoma. Works fine with Homey.

I have no Somfy RTS, just “normal” Somfy motors with Fibaro roller bling controllers, it works like a charm. Power consumption reporting, position reporting, nice and smooth controls.

Somfy RTS, 3 screens running perfectly! When you make a flow, let Homey send the commands with delays between the screens otherwise (you could have) a command sometimes doesn’t reach the screen.

Off-topic: Curios on how you made it report the position? I can just tell it to open / close the blind right now. I couldn’t get my roller shutter to be configured as Venetian blind; may that be the reason? On-topic: Yes, it’s 433 MHz where Somfy Radio controlled devices communicate.

Homey suitable for Somfy?

I own io (sunscreen)and rts(heater)products from somfy and they work perfect. IO is a closed protocol. For io you need the tahomabox to control with Homey.
