What Hacker News says
4 sourcesI am planning to do this soon(TM).
Probably starting with ESPHome to control my heat pumps over IR.
The remote works but I forget to turn it off when not in one of the rooms, and it can't do smarts like keeping temperatures in desired bounds.
An ESP32 running ESPHome with high power IR LED, a presence sensor, temperature sensor, and some pre-built library to control heat pumps[1]. it looks like it should be fairly simple to implement with Home assistant.
Now if I could only disable the beep from the heat pumps receiving commands.
I would like to do smarter lighting, but the lack of decent smart light switches that support local control and are also licenced for use in AU are a blocker there.

In I built an offline smart homeFound a link to this library in the documentation. For esp32/8266 it says. Haven't tried it myself.

In Library to send and receive using infra-red signals on an ArduinoI 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/...
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.

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.
