GARAGE DOOR MONITOR

SimpliSafe needs to develop a Garage door Monitor that is incorporated into their system.

And NO its NOT a alarm it would warn you that the Garage door is open. I installed the entry

sensor as a alarm.

Basic idea:

1. Door open - it flashes the simpliSafe base light ( until the door is closed )

2. Door closed - Base station light goes off.

It seems that there a lot of customers that want such a device for the past 4 years

why does simpliSafe not  create a sensor ?  A Gravity switch sensor?
