My Energy

This folder contains tools for monitoring pv system from Ginlong Data Logging Stick Wi-Fi for Solis Inverters. Currently tested with a Solis 4G Three Phase Inverter. There is a possibility it also works with the following inverters: Omnik Solar, Solarman and Trannergy Inverters

The repository has two folders:

  • python-myenergy - app for data collection
  • android-myenergy - app for preview data

The Python script gets PV statistics from an internal website and stores in the database. To view the data, you need to submit your statistics to Firestore.

The following data are collected:

  • current production
  • total production
  • power
  • (optional) weather / sunrise, sunset via (openweathermap.org)
