It pulls data from the Salicru EQX-SUN API and exposes in localhost:9887
Also handle Zero Injection mode automatically from OMIE prices
git clone https://github.com/alejandroscf/prometheus_salicru_exporter
pip install prometheus-client
apt install at
cp config.py.sample config.py
vim config.py
You can find the plant ID in the URL of the Salicru dashboard.
Run main.py
TODO: systemd unit file
File calc_price.py allow you to program zero injection when IDX price will be negative (you pay for injecting energy into the grid).
It takes tomorrow price from OMIE (Spanish Regulator) API, published at 13:00. Then procces it to calculate the aproximate selling price and program with at command to enable and disable inverter's zero injection mode.
