  • Works well on HA with Z2 MQTT without the Sonoff Zigbee bridge. I have three at home, one year now all good. Two of them are outdoors on gates.

    Trouble-free via zigbee2mqtt through homeassistant and sonoff zigbee dongle -e as coordinator. On the positive side, it also has tampered protection. On the negative side, the small 3M surface area.

    It works properly like thousands of similar ones but the difference from other such contacts or from the older model is significant because it gives you the ability to set the time the contact should remain open for something to happen that you have set in a "scene". For example, by opening and remaining open for X seconds or minutes, an alarm can go off, a light can turn on, etc. And of course, if the contact closes earlier, nothing will happen.
