ESPHome Heart Rate Display for Bluetooth Low Energy with M5Stack Core

  • I created an ESPHome configuration that gets your heart rate from a Bluetooth Low Energy fitness tracker and shows it on the display of an M5Stack Core. For now you need the ESPHome development version and it doesn't work with Wi-Fi because of memory usage of the BLE component, but other than that I find this really cool while working out at home with the heart rate sensor on my wrist:
