    • Check the Wi-Fi internet connection.
    • Make sure the Wi-Fi password hasn’t been changed.
    • Make sure the device’s battery is not used up.
    • Make sure the paired Smart Hub is still online. You can check its LED color, if it is not solid green, please power cycle it once, if it still not works, please reset the Smart Hub and configure it with the Smart Sensor once more.
