Solar Moitoring for solarcontroller e.g tracer
View current status of Solar Power life in browser via websockets
Backend stors data in mongodb and calculates day, month and year view
Client(e.g raspberrypi) reads out solar-controller and sends them to server
Example: solar.tost-soft.de
java open-jdk 11 or later, python3, react
To install the application check out the docker folder. To run the Server just execute these three scripts...
./build_backend.sh
./build_frontend.sh
docker-compose up -dTo acces the application configure the port and availability (localhost) in the docker-compose.yml or/and add a reverse proxy to the expost port.
For the client run the checkData.sh script from the client folder. For more Infomation read the client section.

| view.max-year-consumed-watt-hours | max load watt on year graph | 200 |
The client uses python and modbus to read out the status of the solar-controller and sends the inforamation to the server (spring boot aplication). As hardware i use a raspberrypi with an RS485 Adapter us adapter.As software an installation of python3 and pymodbus is nessesary. Also you habe to change the url and token declared in post-data.py in the first lines. Most of the python code comes from here. There are even more scripts for reading statistic-data and so on.
Also there is a script to read out an EPEver inverter.
Tested on IPower Series (IP1500-21). It doese not use the pymodbus library like the other script because the protocol doese not match the standart modbus function codes as i can see. But it seems to be a read registers on function code 67 on address 12552 (x3108) on unit 3. the result contains 22 byte of data
