DIY Govee gateway

This project takes sensor data from a Govee Bluetooth Hygrometer Thermometer H5075 and pushes it into Grafana. This is done using prometheus as a datastore and a simple Kotlin app to accept requests from a ESP32 near the sensor.

Project structure

• sketch contains the C++ code to send sensor data from the esp32 to the kotlin server
• prints contains the .stl file for our case for the ESP32 Himalaya Matrix Core
• server contains the kotlin backend to transform the dataset into a prometheus application
• deployment contains an example deployment in our kubernetes cluster

Requirements

If you want to use this project without setting it up yourself or getting a working ESP32, please contact us at https://everbuild.org/contact or join our discord server. We'll be happy to work with you to get you set up in our cluster.

• ESP32 - We use the ESP32 Himalaya Matrix Core, but any ESP32 should work. You might need to adjust the platformio.ini file to match your board.
• Govee Bluetooth Hygrometer Thermometer H5075
• A Kubernetes cluster with Grafana and Prometheus Operator installed
• An SSL Reverse proxy in front of the kotlin server

Setup

1. Flash the ESP32 with the sketch code
2. Deploy the server to your kubernetes cluster
3. Configure your ESP32 via the serial console to point to your server (Baudrate: 115200)
4. Add a new datasource in Grafana to point to your prometheus instance
5. Build yourself a dashboard in Grafana
6. (Optional) Treat yourself to a nice ESP32 case by printing the prints file
