I added an Aeotec Micro Smart Dimmer (2nd Edition) to my network today. It was able to pair without issue, and turning it on and off from the SmartThings App works as expected.
However, whenever I use the slider to change brightness on the “Things” setting page for the dimmer switch an “Unable to send command” message is displayed and the brightness of the connected light does not change.
I have no issue dimming the light using the physical dimmer switch itself.
I also installed the “Gentle Wake Up” app and confirmed that it was able to gradually increase the brightness using setLevel commands.
Any ideas why the Thing brightness slider is not working?
