MELCloud Binding

This is an openHAB binding for Mitsubishi MELCloud (opens new window). Installing this binding you can control your Mitsubishi devices from openHAB without accessing the MELCloud App and benefiting from all openHAB automations.

Supported Things

Supported thing types

• melcloudaccount (bridge)
• acdevice
• heatpumpdevice

A bridge is required to connect to your MELCloud account.

Discovery

Discovery is used after a bridge has been created and configured with your login information.

1. Add the binding
2. Add a new thing of type melcloudaccount and configure with username and password
3. Go to Inbox and start discovery devices using MELCloud Binding
4. Supported devices (A.C. Device, Heatpump Device) should appear in your inbox

Binding support also manual thing configuration by thing files.

Thing Configuration

In order to manually create a thing file and not use the discovery routine you will need to know device MELCloud device ID. This is a bit difficult to get. The easiest way of getting this is enable debug level logging of the binding or discovery devices by the binding (discovered device can be removed afterwards).
