Steps to reproduce
Nothing special. About once a day this happens by itself.

Expected behavior
No errors in the log.

Screenshots
N/A

Device information
This is on a Generic HT3, with a controller detected as thermostat FW200 (not having an actual EMS thermostat in the system), in a Junkers Ceraclass Excellence ZSC 28-3 MFA E 23.
ems-esp32: v3.4.2
home assistant: 2022.9.6

please attach the debug info. The error is obviously in the topic name '0\x9e\x02\x00\x0cems-esp/' so interested what you set your hostname and mqtt base too
