Several in the community publish their solar production data to PVoutput.org, a free service for publicly sharing and comparing PV output data. Since this Powerwall-Dashboard project stores all energy production data, it is relatively easy to pull this out of the dashboard and publish it to PVoutput on a one-time or regular basis.
This script, pvoutput.py will help pull and publish the relevant energy data to PVoutput.org.
To use the script:
- Sign up at pvoutput.org to get an API KEY - update the settings in the script with your API_SYSTEM_ID and API_KEY.
- Update the INFLUXDB_HOST in the script to the address of your Dashboard host (default = localhost) and INFLUXDB_TZ to your timezone.
- Install the InfluxDB module and run the script:
# Install required python modules
pip install influxdb
# Run the script
python3 pvoutput.py It will run an interactive mode:
Select Custom Date Range
- Enter start day (YYYY-mm-dd): 2022-06-20
- Enter end date (YYYY-mm-dd): 2022-06-26

Done.
You can also add it to a daily cronjob by specifying a optional parameter: 'yesterday' or 'today'.
# Pull and publish yesterdays data
python3 pvoutput.py yesterday
# Pull and publish todays data so far
python3 pvoutput.py todayI used this script to import of all the data since my system was installed. Keep in mind that PVoutput has a rate limit of 60 updates per hour so be careful. If you are only updating once a day, this shouldn't be a problem. I donated to help their cause which also increase my rate limit. That was useful while I developed this script.
