EdgeTX
Receive drone and RC vehicle telemetry from EdgeTX/OpenTX radios
The EdgeTX integration receives real-time telemetry from drones and RC vehicles via EdgeTX or OpenTX radio transmitters. It reads CRSF (Crossfire) telemetry over USB serial and creates vehicle entities with position, attitude, battery state, link quality, and flight mode.
Setup
- On the radio, enable USB telemetry mirroring — this is not enabled by default. In EdgeTX, go to System → Hardware → Serial Port and set the USB mode to CRSF or Telemetry Mirror
- Plug the radio into a USB port on the device running Hydris
- Hydris detects the radio automatically and begins receiving telemetry
To verify or disable the integration, open the command menu (Ctrl+K / ⌘+K), select Configuration, and navigate to Vehicles -> EdgeTX.
Settings
| Setting | Default | Description |
|---|---|---|
| Enabled | true | Enable or disable the device |
Data Flow
Inbound only. The integration reads CRSF telemetry frames from the radio's USB serial port at 400 kbps. No commands are sent to the vehicle.
Entity Mapping
Vehicle entities are created with the ID format edgetx.device.{usb_device_id}.
| CRSF Frame | Hydris Component |
|---|---|
| GPS | geo (lat, lon, altitude), kinematics (ground speed → ENU velocity), gnss (fix type, satellites) |
| Attitude | orientation (roll/pitch/yaw → quaternion) |
| Battery | power (voltage, current, capacity used, charge remaining) |
| Link Stats | link (RSSI, SNR, link quality, TX power, RF mode, packet rate) |
| Flight Mode | navigation (flight mode, failsafe detection) |
| Vario | kinematics (vertical speed) |
Device Detection
The integration recognizes USB devices with:
- Vendor ID
0x0483, Product ID0x5740 - Manufacturer name starting with "OpenTX" or "EdgeTX"
When a matching device appears, Hydris opens the serial port and begins parsing CRSF frames immediately.
