This is a Solar Analytics public API integration into Home Assistant including sensors for the following:
1. Solar PV system status;
2. Daily cumulative 5-minute energy Watt-hours per available channel (up to 6);
3. Generated expected energy to the hour within the day;
4. 1-minute power Watts related reporting of consumed, generated and import-exported.
5. Where costs are configured in the HA Energy Monitoring (fixed, peak/off-peak/shoulder, spot market
- e.g. Amber) provides
> cumulative daily net cost ($)
> average import rate ($/kWh)
> average export rate ($/kWh)
6. Generated energy consumed kWh and % (of all generated), and Consumed energy generated kWh and %
(of all generated).
7. Electric Vehicle total energy kWh broken down into grid sourced (imported) kWh and generated kWh
with % of total charged kWh.
8. Energy history sensor for graphing each SA channel in Apex Charts (Lovelace sample code included
as <SA-apex-charts.yaml> - unfortunately technically limited by HA to 2h20m.
The solution provides daily cummulative consumed, generated, exported and imported energy (Wh). These variables are configured to work with the Home Assistant Energy Monitoring capability. System status information includes daily PV performance (%) and general status as reported by Solar Analytics.
Set-up and updates from previous releases involves the installation of a stand alone file included as a package in the configuration.yaml file - see the <solar_analytics.yaml> file for instructions. To upgrade from a previous version please read the instructions included in the code header text.
HA Energy Monitoring requires the manual assignment of "Grid consumption", "Return to grid" and "Solar production" via the HA Energy configuration page. The individual energy channels (e.g. load_ev_charger, load_air_conditioner, load_stove) can also be added to the HA Energy Manager as "Monitor Individual Devices". Go to HA settings and then search for “Energy Configuration” to make the changes.
This integration draws on the API get calls defined in the Solar Analytics public open API definition. It also makes use of additional gets as learned from the Solar Analytics user portal. https://api-docs.solaranalytics.com/OpenAPI-Specs/sapublic-openapi.yaml
For those using Amber Electric as their electricity retailer and/or with an EV there are additional bonus sensors defined in <amber_forecast.yaml> and <amber_ev_charge_cost.yaml> respectively. See the code header for the detailed description and usage.
