SomnoTrace
FirmwareRecord AirSense 11 data over Bluetooth
SomnoTrace turns a Waveshare ESP32-S3 Touch LCD 1.54 board into a bedside recorder for AirSense 11 AutoSet and Elite machines. It receives data over Bluetooth, saves EDF files to its own microSD card and offers a local dashboard, network-share uploads and integration with the Home Assistant automation platform.
You need the specified board, a microSD card and steady USB-C power. Remove the machine’s existing myAir and phone Bluetooth pairing before connecting.
Official firmware includes a proprietary sleep-stage model licensed for use only within official firmware. Public source builds keep recording and export functions but omit the model. The board’s PLUS-button double-click can start or stop therapy. This is a personal data tool, not a clinical monitor.
- Use your readings in other apps and automations
- Get your data without pulling the SD card
- Read your data without ResMed's cloud
- See your full night, not just a score
- Local EDF recording
- MQTT and Home Assistant discovery
- Optional cloud uploads
