If you'd like a more configurable option, you could go the DIY route and make a wifi infrared bridge using a charger, an ESP8266 module and a few IR leds:

For example, I have one set as a timer that turns on the AC for a few minutes every hour.
Or you could just buy a ready-made IR bridge that has it's own app.
