This sensor has 4 functions as described in the offer: - Activate and - Deactivate (others often do not provide this) via the internal reed relay - Anti-tamper switch function via an extra switch on the rear side. - Low voltage alert function (try it with a weak battery). All those 4 states are transmitted by separate codes which are different in the last hexnumber: close: "E", Open: "A", Battery: "6", Tamper: "7" Works for example with RFLink and Sonoff RF Bridge. Dont know how long the AAA Batterie lasts, but they are easy to replace.
