Check out the ESPhome project[1], now part of the Home Assistant universe. It makes creating ESP32 projects a breeze and has native IR transmit capabilities. This will let you tie the device into Home Assistant which bring integration with nearly everything. You get a great mobile interface, automation engine, and hooks to nearly every smart device currently being sold.

Interesting! I've been looking for ways to integrate my Fujitsu mini-split A/C heads, and while Fujitsu offers a Wireless LAN device [1], it appears to be a 3rd-party device that just emits IR to control the head. The device also depends on proprietary Cloud control and app, and while these have been reversed for HA integration, it seems like ESPHome can serve as an alternative.

  I have done exactly this with my own ducted Fujitsu system. I initially used the IRMQTTServer project from the IRremoteESP8266 library, which integrates into HA through MQTT. https://github.com/crankyoldgit/IRremoteESP8266/blob/master/examples/IRMQTTServer/IRMQTTServer.ino https://github.com/crankyoldgit/IRremoteESP8266/blob/master/... I now use esphome on absolutely everything and it's WAY better, and I was able to eliminate MQTT from my stack. I could have used the built in climate component—it worked 99% perfectly. But in order to make the Fujitsu climate component behave consistently with the air conditioner itself (e.g. setting "dry" mode forces "auto" fan speed) I re-implemented the climate component as a custom component. https://gist.github.com/sjwright/8591ebd36b53bbed588179135c26b2d7 https://gist.github.com/sjwright/8591ebd36b53bbed588179135c2... I have three zones, so I took three "D1 Mini" style ESP8266 clones, attached an IR emitter to D5/GPIO14 and embedded it inside the air conditioner itself. Each AC has a little daughter board for status LEDs and the IR receiver; there's also 12 volts going to that which I use to power the D1 Mini, which in turn regulates a 3.3V output for powering my IR emitter.

    Awesome! Thanks for the info :)
