Somfy ID find

[West (J.W)]

Hello,
I wanted to control my 3x Somfy Mestriaa+50 io drives with my Openhab 2.
RFXtrx433XL has firmware version 1039.
I already installed RFXCOM Binding in Openhab 2 but I don’t know how to get the Somfy ID.
Each of the three drives is already trained with the SMOOVE Origin IO.

It is not a good idea to use the same ID of a Somfy remote controller. If you would do so, the rolling code will become out of sync and after a few commands transmitted by the RFXtrx the Somfy remote becomes useless.

See chapter 9 in the RFXtrx User Guide how to add an additional ID for the RFXtrx in the Somfy motor.

I can’t find anything about the Somfy Mestriaa+50 io. However, it seems like the Somfy IO products do not use the RTS motors. For example, when I check this and look at the “Technical characteristics” then it mentions “Radio Frequency : io 868 MHz”.

If this matches yours, then you cannot control them using the RFXtrx433XL. The RFXtrx can only control the RTS motors which use a frequency of 433.42 MHz.

You can control the IO motors in openHAB using a Somfy Tahoma or Somfy Conexoon and the Tahoma binding.

I don’t have any experience with the Somfy IO products. All my rollershutters use the RTS motors. A “how to” for using the Somfy RTS rollershutters and RFXtrx with openHAB is available here.

Yes on Frequency : io 868 MHz
So I just need that Somfy TaHoma Z-Wave USB-Modul?

I guess you need the Tahoma box for that, however I have no experience with Tahoma. According to the Tahoma binding documentation it supports rollershutters.

The following posting seems like you may be able to do without the Tahoma box:

[SOLVED] Somfy Tahoma Binding can not find shutters, garage door or gate

Hi Morten, there’s recently been some action going on Somfy io devices: [velux] New OpenHAB2 binding - feedback welcome! Control Somfy io or Velux windows with KLF 200 and HTTP binding (the solution I have applied and which is working so far flawlessly) Perhaps it’s of some help for your case, if you want to drop the Tahoma box (for me it was a privacy concern to have all in their cloud).

May be @antares2001 can elaborate how this works and if it would work for you as well.
