Best zwave door sensor for the money.

but I'm not worried as I covered that risk already.)Good sensor for the price!!!

Works better than smart thing sensors on windows

This sensor has been working flawlessly for the last few months

These sensor work well even when the magnet and sensor are far apart

The sensor works great

I disconnected my transformer from the doorbell circuit, and wired the doorbell to the contact posts inside this sensor to work as a replacement doorbell sensor

I have over 100 Z-wave devices working together well in a smart home setup with SmartThings, and these are so far my favorite open/close sensors

The sensor is safe on the outside of the brine tank and the magnet inside.

After having a very bad experience with some Samsung multi-purpose sensors, I wanted the most reliable zWave open/close sensor, and this one seems to be performing well so far.

First positioning the smaller sensor at the midpoint of the larger sensor cured the problem for one door

Great sensor tech, but the horrible tape they provide makes the product next to worthless unless you want to screw it in.

Also, like its sister module - the garage door tilt sensor - it can regard a slightly open door as closed.
