Thermostat State Goes After Connection Lost

[b1scuitdev]

I made a Air conditioner controller with infrared light using NodeMcu ESP8266 V3, i showed it like a thermostat so i can set temperature and mode but if my phone looses connection to home wifi the thermostat state goes

For example:

1. I turned on my ac from the home app and set my AC to cool modeand 25 celcius
2. I disconnected my phone from the home wifi
3. I reconnected my phone to home wifi
4. When i go to the apple home app it shows AC is off but in real its on

How can i resolve this problem?

Also how can i control my ac from homekit when i am not at home?
