A mailbox door sensor that will work in a metal mailbox. Needs a tilt switch that mounts to the mailbox door with a short wire so the battery operated Z-wave transmitter can be mounted outside of the mailbox. If the Z-wave transmitter is inside a metal box, the signal usually can’t reach the house.
Thanks @Terk, did you have to solder the wires or did the Ecolink device have screw terminals?
It has screw terminals.
What distance is it working at? I have the same contact sensors I use for other projects but my concern was the zwave range to the house?
