The CoolMasterNet integration lets you control HVAC through CoolMasterNet.
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.

What people report
CoolMasterNet climate bridges work locally; fan modes map awkwardly and Apple Home sees only three fan steps.

| CoolMasterNet climate | Partly works | Partly in Home Fan shows 0/50/100% steps; auto reads as 100%; touching slider changes mode | Fan mode 'med' non-standard name; reported fixed/closedSaved copyThe problem I have a climate entity from CoolMasterNet bridged onto HomeKit. As seen from Home Assistant, it has four fan speeds: low, med, high, and auto from here, and interacting with it from the Lovelace card works correctly. But, when I interact with it from Apple Home, it instead has three fan states: 0%, 50%, and 100%. When in "auto" mode, Apple Home thinks it's at 100%. If I so much as touch the fan slider, then the thermostat gets changed from auto to high, which is noisy and shockingly wasteful. Trying to debug this, I think there's a mismatch between what the coolmasternet … Excerpt saved from GitHub on 2026-10-23. | Issue #133068 · 2024-12 |
| CoolMasterNet climate bridge | Partly works Local | Partly in Home Fan shows 0/50/100% instead of low/med/high/auto | Unknown fan speed 'top' unsupported; 'med' naming nonstandardSaved copyThe problem My CoolMaster unit reports fan speed top, but the Home Assistant CoolMaster integration does not recognize it as a supported fan mode. Home Assistant logs this warning: Detected unknown fan speed value from HVAC unit: top. Support for unknown fan speeds will be removed in 2026.7.0 Because of that, the integration is relying on fallback behavior today, and this will likely break once unknown fan speeds are no longer tolerated in 2026.7.0. What I expect If top is a valid CoolMaster fan mode reported by the device, the integration should include it in the supported fan mode list so … Excerpt saved from GitHub on 2026-10-23. | Issue #168043 · 2026-04 |
