Parameter MeterType

Default Value: other

Select the Meter Type so the sensors have the right units in Homeassistant.

Please also make sure that the selected Meter Type matches the dimension of the value provided by the meter! Eg. if your meter provides m³, you need to also set it to m³. Alternatively you can set the parameter DecimalShift to 3 so the value is converted to liters!

List of supported options:

• other
• water_m3 (uses m^3/h as rate)

• water_ft3 (uses ft^3/min as rate)
• gas_m3 (uses m^3/h as rate)
• gas_ft3 (uses ft^3/min as rate)
• energy_wh (uses W as rate)
• energy_kwh (uses KW as rate)
• energy_mwh (uses MW as rate)
• energy_gj (uses GJ/h as rate) ⚠️ Not supported by Homeassistant 2025.7 and later! ⚠️
• temperature_c (uses +C/min as rate)
• temperature_f (uses °F/min as rate)
• temperature_k (uses K/min as rate)

!!! Note

Not all options are supported by Homeassistant, see `SensorDeviceClass.VOLUME_FLOW_RATE` in [https://developers.home-assistant.io/docs/core/entity/sensor/#available-device-classes](https://developers.home-assistant.io/docs/core/entity/sensor/#available-device-classes)!

!!! Warning

Since Homeassistant 2025.7, the unsupported options will no longer work, see change in Homeassistant: [Ensure MQTT sensor has a valid native unit of measurement](https://github.com/home-assistant/core/pull/146722).
