Newbie - I hope I'm posting in the right place...
As per title, I'm not getting any units for this Linknlink eTHS temperature and humidity sensor, just the numbers. Is this a known issue?
I didn't search for you, but you might want to see if there are any relevant enties in the error logs to guide you.
There is an app you can use to browse your incoming MQTT packets for troubleshooting purposes called MQTT Explorer.
