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

Home assistant ile kullanıyorum. Açık ve kapalı bilgilerini ayrı kod olarak gönderiyor. Kapı yada pencerenizin durumunu net öğrenebiliyorsunuz. Diğer tek kodlu ürünlere nazaran oldukça başarılı. Tavsiye ederim.

funktioniert tadellos, fühlt sich wertig an, die LED leuchtet sehr dezent also stört nicht, und für den Preis super. Batterie und Klebepads sind auch dabei

2 signal, one for open, second for close, one AAA battery (included in packege)

Works as should for the time being..

Works as expected. Good door, window sensor.

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

Got 5 of them a couple months ago. Out of 5, 2 of them didn't have the anti-tamper switch, I solved that soldering on the pcb a small push button, since they still had the traces for the switch. So far they've been working flawlessly paired with a tasmotized Sonoff RF bridge, in my HA environment.

After working out sonoff door sensors are one code only (Open), I found out about these. They are MUCH better, being able to send RF codes for open/close, and low battery I believe. Confirmed they work well for open/close so that's the main thing. Very good to show contact states in OpenHAB. Works perfectly with Sonoff Bridge flashed to Tasmota. Came with a battery built in too!
