This widget requires the installation of the [pfsense-api](https://github.com/jaredhendrickson13/pfsense-api) which is a 3rd party package for pfSense routers.
Once pfSense API is installed, you can set the API to be read-only in System > API > Settings.
There are two currently supported authentication modes: 'Local Database' and 'API Token'. For 'Local Database', use `username` and `password` with the credentials of an admin user. For 'API Token', utilize the `headers` parameter with `client_token` and `client_id` obtained from pfSense as shown below. Do not use both headers and username / password.
Load is returned instead of cpu utilization. This is a limitation in the pfSense API due to the complexity of this calculation. This may become available in future versions.
