Greetings All,
I'd like to put the Window/Door 7 magnetic switch on my garage door, to be absolutely certain the door's fully closed. (The Eco Link tilt sensors are too ambiguous; the door can be almost 30% open and both upper and lower sensors show "closed.")
The Aeotec specs say operating minimum -20C (-4F). It gets considerably colder than that here. I know battery power will drop, not concerned about that. Does anyone know if the sensor suffers mechanical problems in extreme cold? Resistances drift too far? I'm asking if the unit quits working for reasons other than low battery power. (I could always power it from a wall-wart.)
Thanks for you consideration,
Ben
