switch cannot be paired with Wi-Fi network. Will do get the flashing Wi-Fi symbol orange/green but there's a couple of other flashing things going on. The dim level indicator lights along the top flash As does the chandelier itself. One suggestion the instructions made it was to move the unit closer to the router which is a little difficult when you've got wires connecting the switch to the box in the wall. Also we've got a mesh extension 12 feet from the switch.
