If you want something that'll still work in a decade, look at units that speak Modbus or have a dry contact interface you can wire to an ESP32. Mitsubishi Electric has the MAC-334IF interface that exposes a lot of control locally, and Daikin has their DIII-Net protocol with the P1P2 adapter, both of which have decent integrations in HA without any cloud nonsense. The Modbus route is the most future-proof by far, just a bit more upfront work.

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.
