This is a Home Assistant custom component (sensor) that connects to the Greenchoice API to retrieve current usage data (daily meter data) and tariffs.
The sensor will check in a configurable interval if a new reading can be retrieved but Greenchoice practically only gives us one reading a day over this API. The reading is also delayed by 1 or 2 days (this seems to vary).
- Place the 'greenchoice' folder in your 'custom_compontents' directory if it exists or create a new one under your config directory.
- Add the integration through Settings -> Devices & Services -> Add Integration, and follow the steps there.
