    Very high quality window-door sensor. It works with a CR2032 battery for up to a year. It doesn’t just work with its own Sonoff Zigbee Bridge. I use it under a Home Assistant system with a CC2652R zigbee coordinator. Fully compatible with either Zigbee2MQTT or ZHA applications. It arrived in Pest County within 1 week of ordering from a Czech warehouse.

    superb little sensors, I used to just avoid sonoff for reasons that are not clear to me. what a mistake, cheap and effective! they suffer the same issue as most contact sensors, quite often it's not a flat surface that you're working on.

    The units arrived in soft satchel with multiple sensors but no damage. Out of the box worked and paired to the Sonoff Zigbee Bridge straight away. On opening and removing the battery transport insulation I noted the holding clip fitted very loosely on two of the units. This caused some intermittent battery contact placed small packing underneath and all was well. Attached one to a fridge door as a test to see how many times it was opened and when. Lots of potential applications.

    These sdetectors are very nice. They work fine. The only think is that they are sometimes not easy to connect to the hub. I had to try two or three times to get them registered. The battery support has to be tghten. But when they are setup it is ok.
