Nothing seems to be working. I tried including with security and cancelling when it asks for the code. I moved the hub close to the switch and rebuilt my mesh. I tried two other LZW31-SN’s in other parts of my home to see if it was an issue with the one specific dimmer, but everything results with them coming in as Zwave_S2_Failed and associations don’t work. Could something with Smartthings have changed? Has anyone else had recent success including them as zwave_S0_downgrade? I had no issues about a month ago.
