# 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_l`  (uses `l/h` as rate) **⚠️ Not supported by Homeassistant 2025.7 and later! ⚠️**
- `water_gal`  (uses `gal/h` as rate) **⚠️ Not supported by Homeassistant 2025.7 and later! ⚠️**
- `water_gal_min`  (uses `gal/min` 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).
