It works great but instructions really suck! I returned one thinking it wasn’t working but it was. Check on YouTube for the video on the Shelly guide. I can’t post the link on the review but it will takes 5 min to set it up. Hope that helps

Aunque cuesta algo integrarlo si no estas en el mundo de la domótica, luego es útil para saber si tienes ventanas abiertas si llueve, pudiendo hacer que, por ejemplo, se bajen persianas para que no entre el agua si estas fuera de casa o sin pasar por todas las habitaciones. Tiene sensor de luminosidad por lo que también se puede integrar con el encendido de luces.

... Tür/Fenstersensor meiner Hausautomation. Gründe: - so klein, dass er in den Rahmen der Tür, des Fensters passt und nicht sichtbar ist - über die shelly BLE-app läßt sich a) beacon abschalten: Batterie hält länger b) Firmware updaten - Einfache und funktionale Integration in Home Assistant - Schnelle Reaktion - Zuverlässige Verbindung BLE/Wifi gateway erforderlich. z.B. einer der Shelly mit Bluetooth. Dort in den Einstellungen: "Enable Bluetooth Gateway" Habe auch jede Menge Zigbee-sensoren. Weniger zuverlässig, Batterie hält weniger lang, Reaktionszeit höher, größeres Gehäuse. Umständlicher Betreib ohne Cloud (z.B. Tuya, Smartlife, ...)

Heel tevreden over deze sensor, de installatie is simpel en de werking is goed (al meer dan 1 jaar in gebruik). Ik gebruik ze voor beveiliging en het inschakelen van (garage)verlichting.
