MELCloudHome - Home Assistant Integration

In Apple Home through HomeKit Bridge

What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.

Entity	Shows up as	Note
`switch`	Switch or outlet
`climate`	Thermostat
`fan`	Fan
`binary_sensor`	Sensor (motion, contact, leak, smoke…)
`sensor`	Sensor (temperature, humidity, air quality…)
`water_heater`	Water heater (as a thermostat)

Mitsubishi Electric MELCloud Home ATA/ATW units	Works Cloud	Works in Home HomeKit guide covers fan tile, climate and device triggers	Error code exposed on error_state binary sensors Saved copy Summary The UserContext API already returns an `ErrorCode` setting for both ATA and ATW units, but the integration never surfaced it: the ATW model parsed it without exposing it, and the ATA model dropped it entirely. This PR parses `ErrorCode` on ATA units and exposes it as an `error_code` attribute on the existing `error_state` binary sensors for both device types, so users can see which error occurred (and build notifications on it, e.g. "Heat pump error E4") without opening the MELCloud Home app. No additional API calls, the data is already present in every UserContext poll. ## Changes … Excerpt saved from GitHub on 2026-10-23.
