Ottimi sensori con codice no,nc e batteria scarica...in verità la scheda è predisposta anche per il sensore tampone ma manca il pulsante a 4 pin saldato che si può comunque aggiungere per avere il 4° codice "tamper". Su 10 ordinati uno era danneggiato.

At last sensors, which are sending both open and close signals. Work great with Tasmota and Sonoff RF Bridge.

Love this product. Very cheap, but good quality. A battery comes with it ! Sends a code when opens, and a different code when closes. Can be used with sonoff RF433 bridge flashed with tasmota firmware

Very good product. 2 codes = open/close. Contains battery and strong 2side tape for mounting. Easy to integrate with Sonoff RF gateway and Home assistant

Really happy with my new purchase. Well packages and reasonably delivery time. Two weeks to Spain from UK. Batteries are included . Emits RF signals when opened but also closed. I will buy more for sure.

Working very fine. For open and close state transmitting two different code. Ideal for Home Automation. Very good product.

Un-used since purchase but that's down to me, not the product. Well built and well packaged. Unable to advise how well they work.

Gunstige prijs, snelle levering. Kwaliteit als verwacht. Ontwerp (vooral met het oog op bevestiging) had beter gekund.

Uick delivery and product looks perfect. Haven't used them yet but no reason to think they aren't perfect.

I am very happy to found this sensor. The 2 signal for open and close state are very useful.
