Somfy IO: only Tahoma or also Connexoon?


Hi there,

i am not owing a Homey yet, might be comming soon.

I am about the buy Somfy 2 blinds. I can choose between RTS motor, or IO motor.
What is at this moment (begin november) best motor-type to choose? In combination with Homey.
I also have option for buying a Somfy Connexoon or Somfy Tahoma.

Will the Connexoon also work with this app? https://apps.athom.com/app/com.somfy.tahoma Only one person stating it does. How to contact the developer?


New Homey with Somfy rts 3.1.1 app not connecting with screen

I have a connexoon. It works perfect with this app


Ok, dank je voor je snelle reactie.
Thanks for the quick reply.


Is it also posible to open or close my overhead door controled bij Dexo IO


The IO protocol is closed, that’s why it only works with devices like the Connexoon and Tahoma. If your overhead door works with these, then it will work with Homey.


I heave a TaHoma and can control my blinds but the overhead door is not in the Option.


@CaWe - could you please let me know if you bought Somfy RTS or IO motor and Homey works with it?
Second question - do you have and do you use Somfy Vario or Situo remote control seldom?
Thank you


Hi Petr,

I still haven’t bought a homey yet, but have installed my 2 blinds with io motor, in combination a somfy connexoon (and terrace app), which controls the opening and closing of the blinds.
I use the hand remote control, only, when blinds are closed by timer, and I need to ‘go through’ them, to open and close (remote is easier than using app).

I can supply information about the connection with the homey.

My topic, was for when I wanna buy homey, which somfy control station (Tahoma or connexoon) I had to buy.

Greets, Carsten


When you use the RTS protocol you don’t have to buy the Tahoma or Connexoon. You can use Homey to control them directly. With IO that won’t will work.


3 weeks ago we’ve installed blinds and screens. We have deliberately chosen for Somfy RTS due the closed protocol of Somfy IO and the Tahoma (which in the past was sold with an annual subscription which you had to pay for!)

For me this was the green light to finally buy a Homey. Everything works fine. I’ve created flows that our blinds will close and open at certain times depending on weekday or weekend. In the future i would like to use data from a weather station with regards to sunlight, outside temperature, wind, etc to be more in control of our blinds and screens.

How did the IO motor choice work out for you?


Hi Guys, can you confirm the screens can be closed half way the window? So precision open and close functionality using Somfy RTS, or is this only possible using Somfy IO?


I am not familiar with that functionality. We have 5 RTS motors which can only be fully opened and fully closed automatically
