A Lua script designed to scrape the System Statistics page published by Envoy-C gateways manufactured by Enphase in order to log the following data to InfluxDB for historical purposes:
- wattage/hour produced by the solar array
- number of inverters installed
- number of inverters online
The InfluxDB data can be visualized using a Grafana dashboard.
This script can be useful for off-grid systems without Internet access or for system owners who do not want to report their production statistics to Enphase.
- Enphase Envoy-C gateway
- cURL to query and post data
- Lua >= 5.2
- InfluxDB >= 1.2.0
- Grafana >= 4.2.0
- Create a database named 'solar' in InfluxDB
- Edit the script and update the site, envoyGW and influxDB variables with appropriate settings for your installation.
- Schedule the execution of the script every minute with 'cron', for example:
*/1 * * * * /home/foo/enphase-envoy/envoy.lua
- In Grafana, create a datasource named 'solar' pointing to the 'solar' database in InfluxDB, then import 'solar-dashboard.json' as a new dashboard.
