hvac_mode is "heat", but hvac_action shows "cooling" about ha-dual-smart-thermostat HOT 4 CLOSED

I can see in your configuration that you are using same switch for heater and cooler. This is not correct and can create the issue reported by you. Try using 2 different switch.

You were totally right @ollo69 - this was the reason. I modified the config with two different switches and both problems were gone. Thank you.

I do have a question, though.
My heating system is a geothermal heating pump, which produces warm liquid during the heating season and cold liquid during the cooling season. That liquid is pumped to the pipes under the floor. This flow is controlled by one valve irrespective if it is the heating season or the cooling season. Therefore I had the same switch for heating and cooling initially.

I worked around this by creating a duplicate switch on the same GPIO of my ESP32, which controls the actuator of the valve. But now I have a problem that when the GPIO is ON, I have one switch showing it is on, and the other switch showing it is off. I am thinking maybe I could fix with the on_turn_on / on_turn_off actions in the ESPHome.

However - isn't my situation common and maybe the ha-dual-smart-thermostat could support the usage of one switch for heating and cooling?

This is a special case that cannot be managed with current integration behavior. It requires changes in the logic so that the meaning of the switch is related to current temperature. I think you should create a feature request detailing yours need.
For now I will create a PR to avoid wrong configuration having same entity for heater and cooler.

Thinking better about this, I think that the better (and simplest) solution is to define 2 template switch and a third switch helper (or any other kind of sensor) that just define summer / winter

• switch 1 (heater) will use as value_template the status of GPIO and helper=winter
• switch 2 (cooler) will use as value_template the status of GPIO and helper=summer

Then you can change the helper status based on 1 integration that change value based on the date, or just change it manually when needed.
