Heishamon MQTT after core update 2026.4.3

Configuration
1

After upgrading to Core 2026.4.3 all entries of my Heishamon (Panasonic heat pump) integration were gone.

Only by roling back to a previous version I was able to get the MQTT topics back.

Heishamon firmware 4.12

Did you put in an issue when them to see if they have a problem?

I did not elevate it into an issue because I first wanted to make sure it was not just me
