Script to retrieve current Solar PV data from the Solarman API, and send Power (W) and Energy (kWh) metrics to a MQTT broker, for further use in home automation. Several PV vendors use the Solarman Smart platform for statistics. One example is the Trannergy PV converter.
usage: run.py [-h] [-d] [-s] [-i INTERVAL] [-f FILE] [-v]
Collect data from Trannergy / Solarman API
optional arguments:
-h, --help show this help message and exit
-d, --daemon run as a service (default)
-s, --single single run and exit
-i INTERVAL, --interval INTERVAL run interval in seconds (default 300 sec.)
-f FILE, --file FILE config file (default ./config.json)
-v, --version show program's version number and exit
You can run this script as a Docker container or in Python 3. Either way a configuration file is required. See the sample config.sample.json file in this repository for reference. Also, a Solarman API appid+secret is required, which can be requested via mailto:[email protected].
