Is it possible that in your heishamon config mqtt name has some unusual characters in front?

[kamaradclimber]

With a software like MQTTExplorer, could you look at the messages sent in panasonic_heat_pump/stats and post it here?

[MorVes]

Thank you for your suggestions.
I've restarted Heishamon and got this from MQTT-Explorer:

{"uptime":19695689,"voltage":3.39,"free memory":75,"free heap":29432,"wifi":100,"mqtt reconnects":114,"total reads":3941,"good reads":3941,"bad crc reads":0,"bad header reads":0,"too short reads":0,"too long reads":0,"timeout reads":0,"version":"3.2.3"}

I've opened Egyras/HeishaMon#491 for the same issue (it happens to me as well).
I think the issue is upstream but will leave this issue open for the time being.

I'll close this one in favor of the issue on the main repository. I was able to see those lines directly on the mqtt server so I don't think it is linked to the HA integration.
