Somfy RTS with RFXTRX433E (PRO XL1)

Configuration
1

Hi,

I finally managed to get my RFXTRX433E working with HA using this simple config:

rfxtrx:
  device: /dev/serial/by-id/usb-RFXCOM_RFXtrx433XL_DO2VI0WA-if00-port0
  automatic_add: true
  debug : true

I have one shutter that has a RTS compatible motor working and that is discovered automatically by HA.

But the rest of my home has shutters with Somfy RTS motors, working on the special Somfy 433.42 mhz frequency.
That’s why I have the RFXTRX433E (PRO XL1) and it’s currently working with my Domoticz setup without issues.

Domoticz can learn the Somfy remotes automatically, but auto detection of Somfy signals is not working in HA.

Is this a limitation by HA? Because technically it’s possible, because it works in Domoticz.

Or is there a way to get the device ID’s from Domoticz to use in HA?

Thanks.

In Domoticz you’d still have to fill in unit code and id right? You can manually add them by looking in the docs and following the guide under chapter RFY.

Using RFXMgr you can get a list of your currently programmed remotes that are stored in the RFXTRX433E device. I falsely believed that Domoticz stored the remotes.

If you want to get your list, you can go to the RFY tab in RFXMgr and select the command: “list remotes” and click the transmit button.

I got a list of 11 remotes and converted them to the HA device code and added them to my HA config.yaml.

Example:

The output of RFXMgr:
RFY remote:0 ID:02 04 79 unitnbr:1 rfu1:AC rfu2:0 rfu3:C
becomes in HA: 071a00000204791

Next step is to program the covers into HA. To be continued.

One correction:
071a000002047901
Single digitals always need a leading 0

Hi, I found that one out too by mistake, but thanks for mentioning it.

This is my working config, for whoever needs it too :slight_smile:
