Cannot receive any messges

[tofuSCHNITZEL]

Hi,
I have connected the FAM14 via usb and have the following USB device selection:

but no matter what I select I can never see any "last message received" or any telegrams in the logs...
if I connect the FAM to my PC I can see a lot of chatter on the serial console:

here what I can see in the logs:

Update - it just started working... maybe it needed to "sit" for a bit...
But when switching to fgw14usb and plugging in the FGW14USB I can't seem to get it to receive messages

Hello @tofuSCHNITZEL,

posted errors above are most probably unrelated to your issue and are solved for newer versions. Changing between FAM14 and FGW14-USB should require no changes except the device type in the config.

Unfortunately, you need to properly restart HA. Quick restart is not enough.
