Docker setup with Shelly and CoIoT

Configuration
3

Update 2:
I started nc locally and pointed the Shelly to my computers ip:port to see if it broadcasts, and I get immediate feedback whenever I toggle the switches:

$ nc -ul 5683

So the Shelly is behaving as expected and broadcasting to the configured target, however my HA instance does not seem to pick up on it.
