Trimetric solar meter data logging
Read serial data from a Trimetic meter and publich to MQTT. Using Rasperry pi.
I switched to using an ESP8266 and ESPhome. I am including the files here.
- I installed in a python3 virtualenv using Python 3
- Uses paho.mqtt
- Uses pyserial
- A custom cable to interface the 5v Trimetric serial output to the 3.3V Raspberry pi GPIO
- Read TM2025-TM2030 Technical Information On Serial Data Output_0.pdf
