MELCloud
The melcloud
integration integrates Mitsubishi Electric’s MELCloud
Device support
- Air-to-Air heat pumps, e.g., AC units - Supported
- Air-to-Water heat pumps - Supported
- Energy recovery ventilators - Not supported
- Other - Not supported
Configuration
To add the MELCloud integration to your Home Assistant instance, use this My button:
Manual configuration steps
If the above My button doesn’t work, you can also perform the following steps manually:
-
Browse to your Home Assistant instance.
-
In the bottom right corner, select the
Add Integration button. -
From the list, select MELCloud.
-
Follow the instructions on screen to complete the setup.
Air-to-Air device
An Air-to-Air heat pump provides climate
and sensor
platforms. Device capabilities can limit the available parameters and sensors.
Climate
The following parameters can be controlled for the climate
platform entities:
- Power (using HVAC mode)
- Target temperature
- Operation mode (HVAC mode)
- Fan speed
- Horizontal and vertical vane positions
State attributes
Attribute | Description | Example |
---|---|---|
vane_horizontal |
Current horizontal vane position or mode | auto |
vane_horizontal_positions |
Available horizontal vane positions and modes | auto, split, swing |
vane_vertical |
Current vertical vane position or mode | auto |
vane_vertical_positions |
Available vertical vane positions and modes | auto, split, swing |
Controlling vanes
The horizontal and vertical vane positions can be controlled using the corresponding melcloud.set_vane_horizontal
and melcloud.set_vane_vertical
actions.
Swing mode can also be used to control vertical vane position.
Sensor
The following attributes are available for sensor
platform entities:
- Room temperature
- Energy - The total consumed energy in kWh. Not supported by all models.
- Daily energy - Energy consumption within a 24h window in kWh. This reading resets at midnight on the timezone of the MELCloud service. The exact time needs to be determined by following the sensor value until a reset is detected.
Air-to-Water device
An Air-to-Water device provides water_heater
, climate
and sensor
platforms.
Climate
A climate
platform entity is provided for each radiator zone in the air-to-water system. The following parameters can be controlled:
- Target room temperature
The radiators need to be configured to run in room temperature control mode either through the local HMI or MELCloud. Flow temperature and curve modes are not supported.
Some air-to-water devices allow cooling using the radiator zones. This feature has not been implemented due to the lack of sample devices.
The system cannot be turned on/off through the climate
entities.
State attributes
Attribute | Description | Example |
---|---|---|
status |
Current operation status | idle |
Sensor
The following attributes are available for sensor
platform entities:
- Room temperature for each zone
- Tank water temperature
- Outside temperature - 1°C precision, polled every 1-2 hours.
- Zone flow temperature, polled every 1-2 hours
- Zone flow return temperature, polled every 1-2 hours
Unlike air-to-air devices, air-to-water devices do not report energy consumption in an easily accessible manner.
Water heater
The following parameters can be controlled for the water_heater
platform entities:
- Power - Controls the entire system.
- Target tank temperature
- Operation mode
State attributes
Attribute | Description | Example |
