 * `DHCPLSS_RUN`: You need to map `:/etc/pihole/dhcp.leases` in the `docker-compose.yml` file if you enable this setting. 
 * The above setting has to be matched with a corresponding `DHCPLSS_paths_to_check` setting entry (the path in the container must contain `pihole` as PiHole uses a different format of the `dhcp.leases` file).

 > It's recommended to use the same schedule interval for all plugins responsible for discovering new devices.

 > [!NOTE] 
 > You soft-disable plugins via Settings or completely ignore plugins by placing a `ignore_plugin` file into the plugin directory. The difference is that ignored plugins don't show up anywhere in the UI (Settings, Device details, Plugins pages). The app skips ignored plugins  completely. Device-detecting plugins insert values into the `CurrentScan` database table.  The plugins that are not required are safe to ignore, however it makes sense to have a least some device-detecting plugins (that insert entries into the `CurrentScan` table) enabled, such as ARPSCAN or PIHOLE.
