Sorry aboutmy english.Simple solution is to power up Bridge throug Basic or similar. If you at home,then bridge not working-it means no notifications.
I dont understand.(or my english is really bad).How your lights blinking if bridge is off? PIR connects throug bridge.So i dont see the problem if you use another bridge only for security.
OK,now i understand.Only way is replace sensors battery power to AC power and again,through Basic or similar
I have an Idea about the alarm system
can you make a scene in the app that seem to look like a real alarm panel?
in that panel make it possible to program the sensors that have alarm function.
then make it possible to set / reset the panel as it was a real panel. I think MANY people would like that very much . (hereby my self.) :)
