How to get Somfy io-homecontrol shutters to work locally?

Do io homecontrol work with these?: SOMFY CONNECT UAI PLUS

I think that’s the piece that control4 and others use to control somfy without the cloud.

If you own a Somfy TaHoma box and your motors support HomeKit (like the popular Oximo-io motors), you can move away from cloud to local controlling, by using the HomeKit-Controller integration with the TaHoma box!

The only downside at the moment is, HomeKit-Controller does not support tilt_position a the moment. I just created a feature request for this, if you can vote for it, it would be great.

Hi there. Old post, but I cobbled up a working setup from old parts and an expensive Izymo.

Zigbee shutter control, Izymo transmmitter and 2 cheap 230V relais…

I also put a door sensor in the awning to check if it’s extended or closed. When controlled via HA, that is not a problem, but the IO remote still works, and the position is not transmitted to HA when the zigbee module is not used.

So knowing the awning is open is a must.

Any questions? Let me know.

Well, not so fast…

The cover controller can not be controlled when the original remote is used.
So you have to do a full out/in sweep first to align the awning with the position of the controller.

And there can be a delay between the movement of the awning, when the zigbee controller already thinks it’s moving. So the awning doest not close completely, but then stops because the controller thinks the position has come back to zero.

Adding an additiona relais to force a close, based on the status of the open/close sensor is my short term solution for now.

Hi guys,

Here is my solution that should work:
Instead of Tahoma I now intend to use a Somfy IZIMO transmitter. That triggers my io blinds, when S1 and com or S2 and com are connected. Instead of connecting a shutter switch to the input S1, Com and S2, I connect them to a Shelly 2.5. I run a lot of Shellies already so that is no hustle.

Problem solved and done. And much better: No Somfy cloud space involved, no detour via the Internet and even so a lot cheaper that the TAHOMA

Hi !
Could you provide more information on how you managed to do it ?
I’m very interested to control my IO Blind at low cost AND il local without buying a box.
Nothing seems to fully works for now.

Easy!
What you need is that: Acquista %product-title% da Conrad
Plus two Shelly one.
Then you connect one Shelly to one of the connections and the other accordingly. You then connect the Somfy izimo to your io blinds
If you then switch one f the shellies, the izimo sends the order to the io blinds.
I created an automation or a script for opening and one for closing the blinds
Switch one Shelly on for opening, wait for xx seconds until all blinds are fully open and the switch the Shelly off.

Works fine!

Remark, don’t use a Shelly 2.5! Use two Shelly one . This is important

@Rainer59, could you elaborate on why 2x shelly one iso one 2.5?

I used the RTS Integration which is totally local and it works well, easy to build and cost about £15
I have one Somfy Huna blind which is Bluetooth controlled which this solution does not work for.

Of course I can🙃
The Shelly 1 has switched contacts whicg are potential free. The 2.5 does not.

This is important for the Somfy switch
