Video Doorbell and Alarm system for Homey

I’m looking for a video doorbell and an alarm system which compatible with Homey in my new house. (I live in Europe.)

  1. Video Doorbell: I found the Doorbird and the Ring until today as a compatible devices. Is any other compatible Video doorbell?

  2. As I can see the Satel (Poland) can be a compatible alarm system, but I don’t know how it’s work with Homey. I mean the Homey can use the signal of Satel motion sensors? The connenction is one way or two-way?
    Is any other alarm system which compatible with Homey?

Thank you for any feedback and suggestion! (German or English)
