Telemetry sensors discovery - yaapu/FrskyTelemetryScript GitHub Wiki
Note: The only extra REQUIRED sensor (apart from the RX/TX built in ones) is GPS, all other sensors are optional, the script works fine without them
The script exposes to OpenTX the following variables via the setTelemetryValue() function, this lets end users use them as regular sensors in OpenTX scripts and functions.
| Parameter | Description | Type | ID | Instance | Unit of Measure | Precision |
|---|---|---|---|---|---|---|
| Alt | Altitude [m] | Custom | 010F | 0 | Meters (m) | 1 |
| VSpd | Vertical speed [m/s] | Custom | 011F | 0 | Speed (m/s) | 2 |
| Curr | Current [A] | Custom | 020F | 0 | Current (A) | 1 |
| VFAS | Voltage [V] | Custom | 021F | 0 | Voltage (V) | 2 |
| GAlt | GPS Altitude [m] | Custom | 082F | 0 | Meters (m) | 1 |
| GSpd | Ground/Air Speed [m/s] | Custom | 083F | 0 | Speed (m/s) | 1 |
| Hdg | Compass heading [deg] | Custom | 084F | 0 | Heading (°) | 1 |
| Fuel | Remaining batt % | Custom | 060F | 0 | Raw | 0 |
| IMUt | IMU temp °C | Custom | 041F | 0 | Temp (°C) | 0 |
| ARM | Arming status | Custom | 060F | 1 | Raw | 0 |
On the Taranis you need to run "discover new sensors" in your model telemetry page to use the sensors in OpenTX, the script has to be running for this to work.
On the Horus the procedure is different: start sensor discovery in the model telemetry page, leave it running and go back to the widget page pressing [RTN] without stopping the discovery process. Discovery should be running in the background. Now go back to the sensor discovery page by long pressing [MDL] and all sensors should have been discovered. If this does not work sensors can still be created manually in the model telemetry page.
Notes
- sensor values are passed to OpenTX only when the script receives valid telemetry from the rx!
- sensors con be logged to the SD card, please check the relevant section of the wiki
