Hello. but the bluethooth phone notifications must be enabled every day ???
There is no system that when phone and lametric are neighbors they connect themselves and enable notifications in automatic ???

This feature has already been implemented. Learn more on this here.
Something like this might be possible with IFTTT in the future. Right now though, you can only use IFTTT to send notifications, not to trigger an event when your phone gets them.
I know that has nothing to do with bluetooth, but it would mean you would get notifications from your phone even when it wasn't connected. I still think your idea is good though.
