Thank you guys for helping me. Well I would like to have all devices at one place, but it seems, that this is not possible right now. I had Ring Doorbell (1st gen) but it only have 720p, so I changed it to Ring Doorbell 2 and this one is just crap. Even when my router is 5 m from it, it shows poor signal. I checked it with 3 other routers - no change. I replace it in shop and new unit still have dose problems. So I returned it. Ring 1 and 2 also have sometimes other issues like I had to wait very long time for any info, that someone is near the door. There were situations, where I answered and the visitor just went away, cause he thought there is no one in home...
Robin Pro-Line is expensive AF and other announced devices are wired. So as I thought... I have no option for HomeKit anytime soon 🙁
Have you got any recommendation on other devices (video doorbell + wireless) not necessary compatible with homekit?
Also thanks for info about Circle2 camera. I thought that wireless also support HomeKit.
