A while back, i set up a some lighting using Fibaro Dimmer 2 and direct association (so RF comms is between the Dimmers, not via the Smartthings Controller)
I also got an XStick recently to map out/optimise my Zigbee network. As part of that, I unplugged (and removed the batterys from) my Smartthings Controller for 15-20 minutes.
During that time, i flcked the light switch that controls the direct association, but the light did not come on for a good 5-10 seconds. I tried the other two switches with the same setup - same issue. Same when I switched off again.
What’s going on here? Did removing the Controller from the network put all the devices into panic mode and they swamped the RF airwave with messages that caused an issue with the direct association communications between the Dimmer 2 devices?
