rpi-energy-monitor
Python application to detect pulses from the utility meter LED using a pulse sensor.https://shop.openenergymonitor.com/optical-utility-meter-led-pulse-sensor/
The script counts the number of pulses and sends the data to a Graphite server and also exposes a Prometheus metrics endpoint for scraping.
Dependencies:
apt install python3-rpi.gpio
pip3 install prometheus_client
Pulse sensor configuration:
| Sensor pin | Rpi pin |
|---|---|
| 2 | 1 (3V3) |
| 5 | 3 (GND) |
| 6 | 7 (GPIO4) |
