I am still having this issue - the Lutron plugin module is a device recognized by ST, but manually hitting the top and bottom (on and off) buttons on the module or the Pico (while powering on and off the module) won’t update the on/off state in ST. I noticed that the state does change on the Lutron app. I am confused because Samsung clearly states that these Lutron units “work with SmartThings.” Can anyone help me? Thanks very much.
