Simple diagnostic question: Did it click when it was switched before? Does it still click now or is it silent? If it is silent now, it can be a defective relay or relay related electronic component(s).
I have had the same problem with 2 of my Coolcam plugs. Their led changes on/off status when switched either by hand or via Homey, Homey sees them go off or on, they are still on the Z-wave network and act as a router but they won’t switch “physically”.
