I have a CUL module up and running with some FS20 switches I have. I can control these switches no issue in pimatic and it works great.
But unlike with my RFLink when I press the original remote pimatic doesn’t register the press and toggle the switch in its database.
These are Conrad FS20 switches. The remote shows a command FE3D30212 (it’s a one button remote so it just toggles) when reading from CUL over serial
