| S_HUM | V_HUM |
| S_BARO | V_PRESSURE, V_FORECAST |
| S_WIND | V_WIND, V_GUST |
| S_RAIN | V_RAIN, V_RAINRATE |
| S_UV | V_UV |
| S_WEIGHT | V_WEIGHT, V_IMPEDANCE |
| S_POWER | V_WATT, V_KWH |
| S_DISTANCE | V_DISTANCE |
| S_LIGHT_LEVEL | V_LIGHT_LEVEL |
| S_IR | V_IR_SEND, V_IR_RECEIVE |
| S_WATER | V_FLOW, V_VOLUME |
| S_AIR_QUALITY | V_DUST_LEVEL |
| S_CUSTOM | V_VAR1, V_VAR2, V_VAR3, V_VAR4, V_VAR5 |
| S_DUST | V_DUST_LEVEL |
| S_SCENE_CONTROLLER | V_SCENE_ON, V_SCENE_OFF |
MySensors version 1.5 and higher
| S_TYPE | V_TYPE |
|---|---|
| S_COLOR_SENSOR | V_RGB |
| S_MULTIMETER | V_VOLTAGE, V_CURRENT, V_IMPEDANCE |
| S_SOUND | V_LEVEL |
| S_VIBRATION | V_LEVEL |
| S_MOISTURE | V_LEVEL |
| S_LIGHT_LEVEL | V_LEVEL |
| S_AIR_QUALITY | V_LEVEL (replaces V_DUST_LEVEL) |
| S_DUST | V_LEVEL (replaces V_DUST_LEVEL) |
Custom unit of measurement
Some sensor value types are not specific for a certain sensor type. These do not have a default unit of measurement in Home Assistant. For example, the V_LEVEL type can be used for different sensor types, dust, sound, vibration etc.
By using V_UNIT_PREFIX, it’s possible to set a custom unit for any sensor. The string value that is sent for V_UNIT_PREFIX will be used in preference to any other unit of measurement, for the defined sensors. V_UNIT_PREFIX can’t be used as a standalone sensor value type. Sending a supported value type and value from the tables above is also required. V_UNIT_PREFIX is available with MySensors version 1.5 and later.
