LouvreTec

The Nodo device was purchased from the Netherlands (https://www.nodo-shop.nl/nl/21-rflink-gateway) This uses an Arduino Mega 2560 board and adds a 443MHz radio

There is native support for this device in home assistant. Search the /dev/serial/by-id/ folder to identify the name. It will also show any simlink into tty. In my case this was /dev/ttyACM0

Follow the instructions at https://github.com/filipmaelbrancke/ha-rflink-rts to pair with the existing somfy controller Note the device RTS name, in my case 0A0A0A

In configuration.yaml add:

rflink
  port: /dev/ttyACM0

Then create a cover for the shutters

cover:
  - platform: rflink
    devices:
      RTS_0A0A0A_0:
        name: Louvertec

Note the final '-0' is added to the address as this signifies to use the first device linked to 0A0A0A

Cover

Create a new cover in Lovelace.
