To make the Screen10 work with voice, I had to add a F441 to make work voice and image. that's what my installer told.
So I'm able to see the image on the Screen10 and answer on microphone. (Sorry for my English )
I'm also able t communicate between my 300X display which, my 2nd display which is on hte first floor and my Screen10. This allows to call my wife when I want to tell her something whithout having to go up or downstairs.
OK... Stair Light Button : I don't know because I don't need it as I have Detectors to turn on my lights. I'm not at home right now to check it. Is it possible to check it via MyHome Suite ?Interesting. I will test again. All my video is new and I still need to play it. Could be that I already have some sort of interface installed but I didn't see him do it. Will check. voice 300x to Screen10 also works but its a bit OTT in my open plan house, I can shout and its easier too
Does the answerphone work from the screen 10? Do you also have the stair light button on the door video panel on the screen10?
