Video doorbell installation, 230V existing doorbell?

Hello Guys.
I am living in Europe, just got a Video doorbell V1. I would like to use it with my existing doorbell, which works with 230V. My problem is: the original ring button next to the door has only one wire from the existing digital chime, that wire will be shorted, when I push the ring button. How could I install the new video doorbell to work with the existing chime?

Thank you for your advices!

Sorry for the quality, maybe it is better to see, how the original is connected. This digital chime is set onto the rail, where the circuit breakers are set.

Hi @Zoli1983. You can find the instructions for installing your Video Doorbell with an existing doorbell in our Help Center article here. The chime kit you have may not be compatible with the Video Doorbell, as there does need to be a compatible transformer in the doorbell circuit. The Video Doorbell is compatible with AC-powered door chimes operating between 8-24 volts. It is not compatible with wireless door chimes or any chime/intercom system using a DC transformer.
