Question

I have 3 IKEA plugs that recently quit working. If I unplug the and plug them back in, they will work for awhile. These are the only hardwired zigbee devices I have. They worked for over a year before they just stopped. Any ideas on how to get them to stay connected?  

Answer 1

If you move them to be closer to your ST Hub do they work reliably? If they do that suggests that the ZigBee signal at their usual location needs to be improved. Adding more ZigBee Repeaters may help, but it might also be worth changing the ZigBee channel in the ST Hub to avoid any overlapping WiFi networks that may have appeared.  

Answer 2

I've of mine recently dropped off the network so had to be excluded and re-added. Have you tried the same?
