solar_metric

Prometheus metric for our solar array and other energy-related stuff.

It takes its values from various MQTT messages provided by our infrastructure.

We use https://github.com/bohdan-s/SunGather to create MQTT messages with data from our solar array:

• SunGrow SH10RT - Solar Hybrid Inverter
• SunGrow SG12RT - Solar Inverter

Additionally, various ESP8266 with DS18B20 temperature sensor running Tasmota do also emit MQTT.

Install

git clone https://github.com/Eigenbaukombinat/solar_metric.git
cd solar_metric
python3 -m venv .
bin/pip install -r requirements.txt

Usage

There is an optional mqtt_server parameter which defaults to localhost:

bin/python solar_metric.py --mqtt_server mqtt_server_hostname

The prometheus metric is then available via http://localhost:5055/metrics
