What version of Home Assistant Core?

core-2026.6.3

Describe the issue

I have a WH-SDC0509L3E3 + WH-WDG09LE5 and I am not able to add a thermostat to the dashboard. It is possible to add a thermostat for the water tank, but the room temp is not possible to control as well as functions as heating or cooling.

Please help, I know it is a pain to work with the Panasonic cloud, so it must be difficult to keep this integration active as they surely do everything to block it (yes I am totally fed up with Panasonic, I never will buy one of they're products again).

So I hope you can help me.

Thanks!

There is currently some issues with the Aquarea part of this Integration, see if 2026.6.2 works better.

Hi, great you fixed it, thanks a lot, very happy to have the thermostat back!

I had automations, turning cooling or heating on and off, cooling can not be selected in the pulldown anymore, any clue?

Can you give 2026.6.6 a go and see if it works better

Upstream issue tracking the empty-zone problem for Aquarea monoblock devices: cjaliaga/aioaquarea#73\n\nRepo-side diagnostics (zone count logging + info-level warning) added in PR #488.

Still bad again. Updating or restarting does not matter. Heishamon is the new goal for me.

Try the latest version I've implemented the aquarea api into my lib.
