Mill integration gives an error when used in a scene

[jm-cook]

The problem

If a device from the MILL integration is used in a scene, the whole scene fails to turn on. The error being raised is in the stack trace below, but here for convenience:

File "/usr/src/homeassistant/homeassistant/components/climate/init.py", line 493, in set_hvac_mode raise NotImplementedError()

I have a gen 3 mill panel heater and am using the direct integration (ie not cloud)

When used in a scene, the scene controller tries to set the target temperature. This works with other climate devices.

What version of Home Assistant Core has the issue?

2022.11.4

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?
