### Description
As reported here https://github.com/iobroker-community-adapters/ioBroker.ring/issues/261 by @Vijabei there seems to be a new version of the `lpd` doorbell

I will give him an update of the iobroker adapter soon, so that he can check if everything else works as with the other doorbells.

Best Regards 

Thiemo
