alt Hacker NewsOT: I'm looking for some way to control my AC via Infrared. I have a few pretty standard AC units with IR remotes. The ones with a display on it, that just transmit all the settings on the remote via IR on every button press.
Some device I can mount in proximity, that controls the AC, but preferably also has a temperature and humidity sensor included.

I use http://getmysa.com for this. they have their own app and scheduling, but i just automate mine via homeassistant

Some ACs have UART interfaces inside that can be fairly easily hooked up to an esp32.
You could also buy an IR transmitter module from AliExpress and add a temperature/humidity sensor chip on I2C like an SHT41.
