Mitsubishi Comfort
mitsubishi_comfort
The Mitsubishi Comfort integration connects Mitsubishi Electric ductless minisplit heat pump and air conditioning systems to Home Assistant. It communicates directly with each indoor unit over your local network for low-latency control, using the Kumo Cloud account only for initial device discovery and credential retrieval.
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
Mitsubishi Kumo units are controlled locally, but local credentials come from the cloud; new accounts in 2026.9 stopped receiving local info.
