Side note, Mitsubishi mini splits suck at native integration But, an esp32, 5 soldered wires, a plug off of Amazon, and an esphome flash and boom, full integration and sensor data. It jumps into a diagnostic port, so tons of information, even compressor frequency.

Each row is one report from a GitHub thread, an integration’s docs, or r/homeassistant. Check the date and the linked source before you buy.

In ReReHome

Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
