My Mother is unable to hear her cell phone ring when at home and when she does not have her hearing aids in.
The idea is to have a phone charger station and next to it, 'something' to know the phone is ringing or vibrating
Then have a few remote lights to blink when the phone rings. (kitchen, bath, living room, etc)
My thoughts are to use a simple RF to alert the remotes.
The 'something' to detect a cell phone ring is where I am asking for suggestions.
If you were to be able to control the mode of the phone, ring, vibrate, etc, and it was hard wired to a place, what would you us to sense the phone ringing ?
