The problem

UPDATE / EDIT: It is not related to the HA upgrade. It is related to some change MELCloud have done on their servers.

Same issue here after updating HA. Climate entity is not created.

[Impedanz]

Thank you for opening that issue! Same Error here after Update :*(

[olealm]

Same issue here after updating Home Assistant OS to 11.5. Climate entity unavailable. Tried deleting and re-adding my heatpump, but climate entity was not created.

[helio58]

Same problem no climate entity. Climate entity unavailable . Core 2024.1.6

[98ultimate]

Melcloud app on android gives this warning message. Can not access heat pump now.

[Nisssen]

Same issue here after updating Home Assistant OS to 11.5. Climate entity unavailable.

[machadolucas]

Same issue here after updating Home Assistant OS to 11.5

[Dirkhaan]

Same here, also after updating the HAOS to 11.5

[Lantoit]

Same issue, I've downgraded Ha to previous version without success.

[Osconse]

Same problem. I have even restored a Home Assistant backup and it still doesn't work

[vilppuvuorinen]

Well we had a good run with this thing.

I'm guessing the only option is would be to drastically reduce the polling frequency to once in 10-20 minutes and hope the load will be acceptable. Let's see how it goes.

The best workaround is to replace the wifi module with a ESP and cut out the cloud component entirely.

[Beamer28582]

Same her. In spite of Backup it doesn‘t work.

[98ultimate]

The best workaround is to replace the wifi module with a ESP and cut out the cloud component entirely.

Lets hope 500€ wifi module is not useless forever. Waiting useful solution from Mitsubishi if wifi module becomes useless.
