…oud for tofan-wk01 models Add two fallback mechanisms to Thermostat class to handle thermostat models (e.g. tofan-wk01) where the MIoT 'on' property is not pushed by the Xiaomi Home cloud: 1. Parse ac-state composite field to extract power status (P: 0=on, 1=off), target temperature (T) and fan level (F) 2. Subscribe to mode changes as a fallback — when mode changes but _prop_on wasn't updated, infer the device is ON Also adds hvac_action property to correctly report COOLING/HEATING/FAN/DRY state based on the current mode. Fixes: Thermostat climate entity hvac_mode stuck at 'off' and target_temperature not updating when changed from Mi Home app.

Problem
For thermostat devices (e.g. tofan-wk01 models) connected via
xiaomi_homecloud integration:offRoot Cause
The
Thermostatclass relies solely on the MIoTonproperty (thermostatservice →Switch Status, bool format) to determinehvac_mode. However, the Xiaomi Home cloud does not pushonproperty changes for this thermostat model — the power state is likely encoded in other fields.Fix
Two fallback mechanisms added to
Thermostatclass:1. ac-state composite field parsing
Some thermostat models push an
ac-stateproperty as a string encoding multiple state fields (e.g.P0_T25_F1). Added parsing logic to extract:P: Power status (0=on, 1=off) → updates_prop_onT: Target temperature → updates_prop_target_tempF: Fan level → updates_prop_fan_level2. Mode change fallback
When
modeproperty changes but_prop_onwas not updated, infer that the device is ON. This covers cases where the cloud only sends mode but not power status.3. hvac_action property
Added to correctly report COOLING/HEATING/FAN/DRY/OFF state based on current mode.
Testing
Tested on tofan-wk01 thermostat (midea-based) with HA 2026.5.0. After patch:
