I just added a Lutron Dimmer switch. It is setup and working in the Lutron app with no issues. Added it to Hubitat and the device was created.
However it did not work. So I checked the logs and noticed that it was sending the commands fine but getting no RCVD back except for when I sent the off command. I tried deleting it, re-adding it, rebooting the Lutron hub, nothing.
Then I turned the switch on manually. Sent the off command, and it went off. Sent the on command it went on. Go figure.
