    Everything works fine. I confirm that if the Wi-Fi access point is not near the location of the sensor installation, then there will be problems with the connection-its sensitivity is weak. And in general, it works fine.

    From other suppliers received quickly. Everything works. But the included two-sided Scotch tape is weak-the sensor drops periodically, which gives a false operation.

    26 June 2021
    Fast shipping! I was told that the delivery from Russia and did not read the characteristic. WiFi in this kit d025 No. There's a controller to this Reed. Pay attention.
    24 June 2021
    The magnet is weak, there are no holes for fastening to the screws. Configured from the first time, used the Tuya application-the translation of the curve, off means closed. Where not important is the malignant reaction to the event, but only the fact of passage or opening a normal device. Looks a little cumbersome.

    So far very pleased. I took it to the workshop. It is important that there is not in the visibility zone of the motion sensor-cameras. Surveillance cameras have IR illumination that causes false positives!

    Avevo comprato due sensori di porta sonoff con il bridge, ma nessuno dei due sensori mi ha soddisfatto. uno non ha mai funzionato e l'altro ha smesso quasi subito. questo sensore Kerui si è associato subito e funziona benissimo.

    2 June 2021
    All right but without batteries for a few more cents they could have been included and bought the item the same, I know the brand and it's trusted.
    1 June 2021
    Connection of the sensor to tuyasmart by Wi-Fi, when receiving alerts there is a delay of ~ 20-40 seconds. If there are difficulties in recording the sensor, force the IP address of the sensor in the router settings.
    31 May 2021
    In appearance, everything is fine, in the case has not yet checked, but, having experience with this firm, I'm sure of the quality.
