The shared catalogue that says what a reading measures and in which unit.
metric_id. The catalogue is shared across all devices, so a soil moisture reading from any device is id 220 in percent. The API stores the value as sent and does not convert units, so the device converts to the catalogue unit before posting.
| ID | Metric | Unit | Notes |
|---|---|---|---|
2 | Voltage | V | Battery voltage where the device reports volts |
30 | Capacity | mAh | |
70 | Temperature | °C | Soil or air, by device channel |
90 | Wind speed | m/s | |
110 | Humidity | % | |
120 | pH | pH | |
140 | Luminosity | lux | |
160 | Direction | ° | Wind direction, degrees from north |
200 | Battery | % | Battery level where the device reports a percentage |
201 | Signal | % | Radio signal strength as reported by the device |
220 | Soil moisture | % | Volumetric water content |
224 | Conductivity | mS/cm |
200 when the device reports a percentage and 2 when it reports volts. Never scale one into the other with a guessed curve.
221 to 223 (nitrogen, phosphorus and potassium) exist in the catalogue but aren’t a supported reading. Don’t build on them.
