I just bought a Vera 3 and playing with it. I connected some devices with success.
My (Noob) questions are:
1 - How can I create a scene which switches a lamp ON when activated by a Moving_Sensor between Sunset and Sunrise?
2 - How can I switch off all lamps in a room when 1 lamp is switched of manually?
(IF all lamps are on AND one lamp is switched off THEN switch of all lamps in a room)
For #1 you can do it with a third-party plugin (“app”) called the Combination Switch. It’s free to dowload. More info here. Your scenario is described step-by-step here. Perhaps try to get some simpler scenes working first, so that you get used to the Vera3 interface (“UI5”).
For #2 you could also use the Combination Switch. This specific scenario hasn’t been discussed before. Let us know how you get on with #1 first.
