 ### Details / Process
 As mentioned above the script is inspired by @RalfZim fronius smartmeter implementation.
 So what is the script doing:
 - Running as a service
-- connecting to DBus of the Venus OS `com.victronenergy.grid.http_40`
+- connecting to DBus of the Venus OS `com.victronenergy.grid.http_40` or `com.victronenergy.pvinverter.http_40`
 - After successful DBus connection Shelly 3EM is accessed via REST-API - simply the /status is called and a JSON is returned with all details
   A sample JSON file from Shelly 3EM can be found [here](docs/shelly3em-status-sample.json)
 - Serial/MAC is taken from the response as device serial
