        0 = Disabled (Default)
        1 = Enabled

    ext_notification_plugin_active
        Is your external circuit triggered when our GPIO is low or high?

        0 = Active Low (Default)
        1 = Active High

    ext_notification_plugin_alert_message
        Do you want to be notified on an incoming message?

    ext_notification_plugin_output
        What GPIO is your external circuit attached?

        GPIO of the output. (Default = 13)

    ext_notification_plugin_output_ms

# Usage Notes

For basic usage, start with:

	ext_notification_plugin_enabled = 1
    ext_notification_plugin_alert_message = 1
    
Depending on how your external configured is configured, you may need to set the active state to true.

	ext_notification_plugin_active = 1
    
# External Hardware

Be mindful of the max current sink and source of the esp32 GPIO. The easiest devices to interface with would be either an LED or Active Buzzer.

    
# Known Problems

* This won't directly support an passive (normal) speaker as it does not generate any audio wave forms.
* This currently only supports the esp32. Other targets may be possible, I just don't have to test with.
