Integration with existing UI for CA350

[mat3u]

Hello,

I was tinkering over weekend to make working this firmware with existing Lovelace controls (eg. https://github.com/mweimerskirch/lovelace-hacomfoairmqtt). Result:

I can see temperatures, fan duty and can control fan level.

I made some changes, some of them makes sens (like last will) other probably could be handled by HA itself by smart configuration. Eg.:

fan_mode_command_topic: "comfoair/climate/fan/set"
fan_mode_state_topic: "comfoair/climate/fan"
fan_modes:
  - off
  - low
  - medium
  - high

Instead changing firmware these topics could be done using templates, but I was unable to write template that is working and produces results I want.

You can see changes I made and pieces of configuration here: https://github.com/mat3u/comfoair-esp32/tree/hacomfoairmqtt-compatibility. If any of this features is interesting then, let me know.
