Python script to read sensor values over BLE from Viatom wearable ring oxygen (SpO2) monitors.
Reads values once every 2 second and logs to console or log file. Also publishes values to an MQTT broker if so configured.
This branch works with the Wellue Wrist Wearable Sleep Monitor, but should theoretically maintain compatibility with the Viatom ring oxygen monitors:
- PO1
- PO2 (Wellue O2Ring)
- PO3
- PO4
- PO1B.
Install BluePy for BLE and InfluxDB
sudo pip install blueply
Scan while wearing the device to determine it's BLE address.
Note: Ensure the device is not connected to any other monitor (ie the mobile app) before scanning.
sudo python3 viatom-ble.py -s
Look for a device with Complete Local Name that is associated with the ring monitor device and note its Device address (six colon-delimited octets, eg aa:bb:cc:11:22:33)
Edit the python script viatom-ble.py and enter the BLE address where the ble_address variable is initialized.
Change the InfluxDB settings in py3_health_to_influxdb.py to match.
Optionally could setup visualizer like Grafana for seeing these in real time.
Test BLE connectivity while wearing the device.
python3 viatom-ble.py -v -c
Start connection with Grafana/InfluxDB with the following:
python3 py3_health_to_influxdb.py -v -c
Look to organize code, and test/validate the systemctl methods with the new influxdb integration.
Add influxdb and other parameters as opts to be optionally set with flags.
