ESP32 Tilt tracker

The Tilt Hydrometer is a sensor that transmits the specific gravity and temperature measurements of the brew it's in. These readings are broadcasted as a Bluetooth Low Energy (BLE) iBeacon signal more details.

The company behind the hydrometer also created a Raspberry Pi build which has all features built in already, it is able to capture the BLE Signal, sends it to a google excel sheet and show the results on a self-hosted webpage.

What I'm trying to achieve with the ESP32 build is that the BLE signal is captured and published to a Time Series database (InfluxDB) which is then made readable with a Grafana page to display these results.

The ESP32 code is on GitHub
