2.10.04 breaks turning off Moes thermostats: /sensors/70/config/mode invalid value, off, for parameter mode

[HenningGithub]

Describe the bug

After updating the deconz plugin in home assistant to 6.8.0 yesterday, my thermostats won't turn off any more (climate.turn_off service in HA).
Turning them on (climate.turn_on in HA -> mode: "heat") still works.
It worked just fine until the update. I had addon_core_deconz_6.7.2 before.

HA log shows:
pydeconz.errors.RequestError: /sensors/70/config/mode invalid value, off, for parameter mode

Additional context

[Mimiix]

Home-assistant tries to set a mode that isn't available in the rest API.

@Smanar did you change anything to this thermostat? Can you help debug a bit?

[Smanar]

Have found the problem, haven't see what happen yet, but I think it s definitely my fault.
BTW, you haven't an unix machine to make test ?

The FIX will be light, perhaps we can have it in the next beta.

[HenningGithub]

Unix yes, Linux no.
You probably have released 5 more versions before I get around to even set up cross compilers to armv7l-linux...

[Smanar]

Lol, yes sorry, but from my memory HA use to beta version ?

[HenningGithub]

I have no idea if HA can be tricked into using a beta addon. I have always claimed I want to use HA like an appliance, and it isn't too much of a lie ;)
My immediate problem - heaters not turning off is one ;) - was solved by restoring v6.7.2 of the addon right after writing the bug report.
