3. Rename `secrets.h.example` to `secrets.h` and fill in your credentials.
4. Flash ESP32 with the code. Connect the INA219 module according to the schematics and power up the ESP32.
5. The ESP32 will connect to your WiFi and start sending data to the InfluxDB. InfluxDB webgui is available at [http://localhost:8087](http://localhost:8087). You can now start the Grafana dashboard and connect it to the InfluxDB. The Grafana dashboard is available at [http://localhost:3002](http://localhost:3002).
