esp32.heartrate
FirmwareRelay an H9 to two Bluetooth receivers through ESP32
esp32.heartrate makes a separate ESP32 board read H9 Bluetooth heart rate and intervals. Its local web interface exports session summaries.
Flash an ESP32-S3 to relay readings to two receivers; Mini D1 has no relay. The archive holds 64 sessions with condensed readings, rather than every raw sample.
- Keep readings off Polar’s cloud
- See and share live heart rate
- Use readings in other apps
- Keep your own recording files
- Local web charts
- Up to 64 stored session summaries
- Optional ioBroker ESP-Hub connection
