sensor.greenely

Custom component to get usage data and prices from Greenely for Home Assistant.

Because Greenely doesn't have an open api yet, we are using the Android user-agent to access data. Data is fetched every hour.

Installation

Using the tool of choice open the directory (folder) for your HA configuration (where you find configuration.yaml).
If you do not have a custom_components directory (folder) there, you need to create it.
In the custom_components directory (folder) create a new folder called greenely.
Download all the files from the custom_components/greenely/ directory (folder) in this repository.
Place the files you downloaded in the new directory (folder) you created.
Add a sensor - platform: greenely to your HA configuration.

Using your HA configuration directory (folder) as a starting point you should now also have this:

custom_components/greenely/__init__.py
custom_components/greenely/sensor.py
custom_components/greenely/manifest.json
