The Aeon Labs Smart Energy Switch DSC06 used to be a very reliable device for me. Yesterday I tried adding two of them to my hub, and both of the devices are not responding to commands after initially pairing. I have tried both the SmartThings supported Z-Wave Metering Switch device type and the community device type from @jpansarasa .
I have also tried rebooting my hub.
The devices will pair. But after pairing they do not respond to the hub. Looking at all events for the device I see only the messages from the hub to the device and no responses from the device.
