The first garage door sensor I received worked for awhile, then after about 4 weeks started to show "low battery" warning and always showed "open". By tapping it gently it would work for awhile, but before I could get a new battery (4 weeks on a battery is not good), it went open while armed in the middle of the night setting the alarms off. Talking with support it was determined the unit was defective and a new one shipped. New one has now arrived and the same problem persists. It will arm normally "some times", other times is reports "garage door open". I disabled it as I am afraid it will set itself off again in the middle of the night. Any suggestions. I cannot find a tech phone number anywhere on your site. I like the system but am now not so sure. Two friends have asked me about my system and I have told them to hold off buying it.
How can I get the garage door sensor to work properly?
