Shelly 3800235266618 BLU Black Bluetooth Door/Window Sensor

Low profile and work well

Parfait, comme la plus part des produits shelly.

I added this to a smart home setup and it has worked really well so far. It is a compact Bluetooth door and window sensor that detects when something opens or closes and can trigger notifications or automation scenes. Installation was simple. It mounts with adhesive and the sensor and magnet align easily on a door or window frame. Once installed it disappears pretty well visually because the device is small and lightweight. One thing I like about this sensor is that it does more than just detect open and close. It also measures tilt angle and light levels, which opens up some additional automation possibilities depending on how you are using it. Battery life is rated up to around five years using a coin cell battery, which is nice because it means you are not constantly swapping batteries like some sensors. Overall this is a solid little sensor if you are building out a smart home or security setup. It is easy to install, integrates with automation platforms, and gives you reliable notifications whenever a door or window is opened.

... 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, ...)
