 - Enter the port number (default: 502) of the inverter in the `Inverter Port Number` field.
 - Select `Yes` in the `Add missing devices` to create the devices when the inverter is added. Select `No` after deleting unwanted devices. Leaving the option set to `Yes` will recreate the deleted devices once Domoticz is restarted.
 - Select an `Interval` (default: 5 seconds); this defines how often the plugin will collect the data from the inverter. Short intervals will result in more accurate values and graphs, but also result in more network traffic and a higher workload for both Domoticz and the inverter.
+- Optionally change the `Log level`; this defaults to `Normal`. When selecting `Extra`, the plugin will print all the information it received from the inverter in the log.
 - Optionally turn on `Debug`; be aware: this will generate a lot of entries in the Domoticz log!
 - `Add` the inverter.
