Mqtt - new device not added?

Configuration
1

Hello Guys,

i’m pretty new to HA and it is a great tool! But since today i have a strange problem.
All my esphome nodes reporting to a local mqtt and are all visible in HA. The same mqtt has also another topic called vzlogger/sensor/chn0 but i cannot find this topic in HA. Why does this new message not appear in HA? Auto discover is activatet.

Cheers, Can

Does this topic have an associated mqtt discovery message ?

This is a good question. But i must confess i have no idea where to look for it. Is this a special topic of the mqtt sender?

The mqtt devices needs to know how to send a mqtt discovert message. If it does not, you need to configure it yourself in .yaml, or create a discovery message yourself and publish it to the mqtt broker.

Now i think i got you right. MQTT has already the device seen. It’s available via MQTT Browser. But it does not appear in HA. That’s the trouble i’m facing…

What device is it ? See how to define it in .yaml:

and writing a discovery message:

Thanks a lot! That’s a good overview!
