Greetings,
I'll work on you IOT based air conditioning system and will make it possible to control air conditioning system remotely. I have done this before and am able to do it again.
I have been through attached Arduino project code, this is just sample code, I can do far more than this.
Expertise:
I am an expert IOT developer with hands on experience of Arduino, NODE MCU. RaspberryPI, MQTT
Do you have some time to discuss you details?
