Zen Thermostat support incomplete, multiple bugs. Works in ZHA, not in z2mqtt.

What happened?

OTB does not support setting temperature, nor does it allow the HA climate entity to set temperature. The following tweaks made it semi-work, but this thermostat is fully supported in ZHA so this is a z2mqtt issue.

The following had to be added, as this attribute was not automatically added:

Publishing an mqtt message to zigbee2mqtt/IEEE Address/set with the payload {"occupied_cooling_setpoint": ""} made them show up in HA, however it shows both heating and cooling on the HA card despite being set to "cool" mode.

Additionally, setting temperature works roughly 30% of the time, at best. This device is fully and flawlessly supported in ZHA, but I am trying to bring everything under one umbrella. I would be happy to work with someone to test out tweaks/fixes or to provide further data. Thank you!

What did you expect to happen?

The device would work like it does with ZHA

Thank you to @andynbaker for his tips here, which got me from not working at all to semi-working.
