Hello there!

By taking the time to implement it using the Homie convention I expected to be able to do MQTT Thing Auto Discovery but nothing shows up.
I have sucessfully using the Online verificator for Homie 3+, well, I must actually move the order a little bit, but it seems to be valid Homie 3.0.
Auto Discovery should work, -right? Can anyone tell me what’s wrong? Thanks in advance for your kind help.
EDIT: Maybe I have to add the thing manually and then the channels will be auto discovered?
When doing that I’ll need to add a Homie device ID. The help text says Homie Device ID. This is part of the MQTT topic, e.g. "homie/deviceid/$homie" Which is wrong. It actually expects just the device id, e.g. inverter-123456. I did that and the channels are now detected.
The question remains though if the thing shouldn’t be autodiscovered…
