# Aqara W600

Works well in `over_climate` mode. It has an internal temperature calibration function, making it a good candidate for temperature synchronization. It is very comprehensive in Zigbee, but its capabilities are much more limited in Matter over Thread.

> [!NOTE]
> Zigbee2MQTT only exposes the valve position as a read-only value: _VTherm_ cannot use [direct valve control](https://www.versatile-thermostat.org/en/docs/self-regulation/#self-regulation-by-direct-valve-control) and regulates through the setpoint. For this reason, the W600 is partially compatible. See [TRV without direct valve control](https://www.versatile-thermostat.org/en/devices/trv-no-valve/) for the recommendations.

## Compatibility status

- **Partial**: This device is supported by Versatile Thermostat, but some advanced features may not be supported. Devices: Aqara W600

## VTherm configuration

### Initialization

Go to your settings, then integrations, then click on add a new integration. Search for Versatile Thermostat.

Click on Thermostat over another thermostat.

### Basic attributes

Go to the "Main attributes" section.

1. Choose a name for your thermostat
2. Set the temperature sensor for your room
3. If you are using the Zigbee protocol and you have a "last_seen" entity for your temperature sensor, fill it in.

You can validate and return to the configuration menu.

### Underlying entities

Go to the underlying entities section.

1. Add the thermostats that will be controlled

You can validate and return to the configuration menu.
