Hi I've searched a LOT
What I would really love is a productised simple door alarm (like a reed switch) but I cant find one anywhere...
what I was thinking is basically what a child would do and yes I could do this multiple ways however I don't see a clean product anywhere...
there are for zigbee
while I can see that bluetooth has a org.bluetooth.profile.alert_notification thats more for phones but it could be used for alerts for a door...
equally a device does not actually need to be even powered on until the door/window is opened then it could become a Bluetooth Smart Beacon sending a URL that the "home.url/.../open"
has anyone done this before with bluetooth ? (I'm not interested in custom RF solutions I want to use a bluetooth linked to a linux controller to monitor things)
appreciate any help !
regards
John Jones
