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 Key' (v2) / 'API Token' (v1). For 'Local Database', use `username` and `password` with the credentials of an admin user. The specifics of using the API key / token depend on the version of the pfSense API, see the config examples 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.
