I have 3 of these. The first two of these devices were trivial to get working. No configuration changes. They just worked. This last one is a different story. Sometimes the LED strip will not light up until the color has been adjusted. Sometimes, not even then. In the UI, I can toggle the LED on, the dimmer will go to 100%, but I have to adjust the color again.
If it’s just the one device that is flaky, it’s identically setup like the others, and it was setup at the same time/same binding version as the others (hence, same Thing definitions), then I would suspect a network or device issue. If it behaves the same close to the controller, then it is likely a problem with the device.
If the three Things were not created at the same time, there was a recent update to the Thing definition, so update to the latest Z-Wave binding and then refresh the Thing definitions by deleting the Thing and rediscovering. After that, double check the Item definitions, since the Channels changed.
Sorry, I should have followed up sooner, but the problem seems to be my power supply was under powered. The strip is rated at 2 amps, the same as the power supply. I replaced it with a 3 amp supply and everything works just fine.
