Description of Change

Problem: The LengCeoi HAVC Remote were recently tested in ST App, which include Thermostat and Fan device type. However the capabilities in plugin shows incorrectly

Expectation Result: The capabilities of thermostat, humidity, fan speed, thermostat mode, thermostat fan mode and set temperature show in the ST plugin.

Current Issue: The plugin show fan mode and fan speed.

Analysis: Is it found that the edge driver(matter-thermostat) will re-assign a new profile while driver initialize, and go to the Fan logic, the fan logic does not check if the device support thermostat, or humidity, which means it will re-assign the “fan-generic” for driver.

The profile name re-assign logic is changed to check if the fan speed is supported.

We don't currently support the fan speed capability for thermostat, and that is on purpose. We have internally discussed adding this, but for now we do not plan to add this feature for thermostats.

I believe similar functionality could be achieved by simply reordering the if-else logic in do_configure. Specifically, if we put the elseif device_type == FAN_DEVICE_TYPE_ID then at the bottom of the ordering, then the logic would see this check first elseif #thermostat_eps > 0 then and would profile based on that logic, only going to the FAN_DEVICE_TYPE_ID logic in the case that #thermostat_eps == 0.
