Aqara Thermostat E1 (SRTS-A01). Add hvac_action report to the converter

[DaN66O]

Is your feature request related to a problem? Please describe

This TRV does not know how to report hvac_action, because of this, it is difficult to work with it in Home Assistant. Knowing temperature and current_temperature, is it possible to create an hvac_action variable in the converter based on the readings of the target temperature and the current temperature and add it to the climate supported_features?

Describe the solution you'd like

Based on the readings of the target temperature and the current temperature, create the hvac_action variable and add it to the climate supported_features.

Describe alternatives you've considered

Based on the values of temperature and current_temperature, create the variable hvac_action in the Home Assistant and then create a new climat

Is it even possible? Radiator valve could ask for heating sooner then the temperature drops or vice versia. Calculating hvac_action is not possible I guess, or is it?

This is where they tried to solve it programmatically in the home assistant https://github.com/Koenkk/zigbee2mqtt/issues/13993#issuecomment-1382697913 I thought it could be solved in the converter.

This is where they tried to solve it programmatically in the home assistant #13993 (comment) I thought it could be solved in the converter.

hvac_action_template: > {% if state_attr('climate.real_trv', 'preset_mode') == 'manual' and state_attr('climate.real_trv', 'system_mode') == 'heat' and state_attr('climate.real_trv', 'temperature') > state_attr('climate.real_trv', 'current_temperature') + 1 %} heating {% else %} idle {% endif %}

His calculation is not right :-(. It determines hvac_action based on the current temperature and target temperature. If target tempersture is higher, then it is consideted as "heating".

I did similar approach and if you use BetterThermostat it does the same thing - but you can set threshold. It is really far from what I want, but could work.

The whole point of my question was not to make new thermostats but to implement it in a standard converter. p.s. I don't use BetterThermostat for the same reason.
