Hi
Can anyone suggest an Indigo way of detecting (i.e. hardware that is Indigo friendly) detecting an upright metal skinned freezer door has been left open.
Someone in the family (not me) has left the door open overnight for the second time ruining all the contents.
I have ZWave Lightwaverf already up and running.
Seems there are four ways to deal with this.
1. Don't leave freezer door open
2. A temperature sensor the freezer that triggers an alarm (worried about the metal skin of the freezer may block signals)
3. A door sensor (same concerns about metal skin blocking signal
4. An energy monitor on the freezer power supply that triggers when the freezer draws too much power for too long ( not sure how I would implement that)
Any ideas, thoughts?
Thanks
