I recently purchased one of the new SmartThings buttons for my SmartThings hub and network. After pairing I used the Smart Lighting App to have the Button toggle a Z-Wave plugin outlet on/off. All worked perfectly. The next day I performed a “Repair Z-Wave Network”. After that, I noticed that the Button was now showing as “disconnected”.
I removed the Button from my Hub (I used the “Remove” function in the SmartThings App). Then I used a paperclip to reset the Button and attempted to re-add it (I followed the instructions on the “Set up and connect the SmartThings Button” web page).
The Button is flashing red and green, and is physically close the the hub (about one foot), but the hub cannot find the Button. I tried it using both the classic SmartThings App and the newer App.
Hub Model: STH-ETH-250
