Constant MQTT disconnects #223

Closed trsqr closed 2 years ago

trsqr commented 2 years ago

I'm observing a constant flow of MQTT disconnects even if my WiFi connection is very good:

Running Igor Ybema's HeishaMon.ino.d1-v2.1-iy-6.bin firmware. I also tried downgrading to HeishaMon.ino.d1-v1.0.bin firmware, but same result.

Any suggestion on where to start the troubleshooting? I actually have two heat pumps with HeishaMon both having the same issue.

If I connect manually to my MQTT broker with mosquitto_sub I don't have any issues with the connectivity breaking down.

And this was caused by two HeishaMons with the same hostname connecting to the MQTT broker.
