“The standard air conditioner not connected you already have can be hacked to be used with a smartphone I’ve got a standard Daikin air conditioner in my home, it’s not a connected device. It’s controlled only by an infra-red remote controller. I’ve made it wifi controlled emulating the infra-red remote controller commands with an ESP8266 microcontroller. This new controller can be placed in a place that “see” the air conditioner and using a small app can talk with an Ios/Android smartphone.”
