    Works with Sonoff RF Bridge. Send 2 separate codes for onOpen and onClose events (see attached photo - screenshot from tasmotized RF Bridge). State changes occur within 1.5-2.0 [cm] range. Blue led blinks on state change. Runs single AAA battery (included).

    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.

    I already own some of these and use these with my alarm system integrated into Home Assistant,they work flawlessly with a long battery life, they also look really well and aren’t to big that you notice round a door or window frame They also send 2 separate codes for open and closed which is great for automation, and a small led indicator on it which activates when the sensor opens or closes. You can remove the sensor once secured with the double sided tape by sliding it off the back plate, this gives easy access to change the battery.

    I use it with a home assistant. It sends off and off information as separate codes. You can clearly learn the state of your door or window. Quite successful compared to other single code products. Would recommend.

    Great sensor. It can send 4 different codes, like this: xxxxxA - open xxxxxE - closed xxxxx7 - tamper (if you add a switch in the unpopulated socket on the board) xxxxx6 - low battery fx: 13DD0A 13DD0E 13DD07 13DD06 I use them with a Sonoff RF bridge, flashed with Tasmota.
