This device is supported by Versatile Thermostat, but some advanced features may not be supported.

Devices: Mitsubishi MELCloud

Configure and use your MELCloud Mitsubishi

Requirements

You need to setup MELCloud integration.

Open your Home Assistant instance and start setting up a new integration.

Limitations

MELCloud is a cloud integration: some commands are lost, and after a restart the auto-start/stop state can be out of sync with the unit. Enable the incorrect equipment state fix to resend the expected state. When you drive the unit by hand, disable the VTherm first, or the fix will undo your change.

The MELCloud fan speeds (1 to 5) do not match the VTherm fan modes, so the automatic fan mode can choose the wrong speed.
