I made a remote control for the DIY air conditioner in the application and learned various air conditioner settings with the ifell function enabled. It works great, the original remote control with the ifell function enabled starts the unit, when the application sees on the electricity meter that the unit has started, it starts a scene in which I have set breaks and temperature switching at the appropriate time, which causes modulation to 250W. It works like this for 20 minutes, then it reaches 550W and when it reaches the temperature, the air conditioning turns off, thanks to which the air conditioner turns on and off much less often.
