FWIW, “Replaced Failed” may actually work. At least it appears that it did for me.
I had a dimmer that was working, but wasn’t talking to my Vera Plus. I was getting “Can’t detect device”, and although I was able to run some luup code found elsewhere on this forum to clear the error, it still wouldn’t connect.
I tried deleting the device and re-pairing it, but it got a different device and altid, which messed up my scenes and existing configuration.
So I restored from backup, put the Vera in exclude mode to remove the recent association. The dimmer was now flashing. I went to the device’s Advanced->Commands tab and clicked “Repair Failed”. It responded with a popup, “Command Sent”, but no add-new-device-wizard.
I then went to the dimmer and pressed the button. The light cycled, but the LED was still blinking. A second tap and it cycled again but this time the LED was solid. Looked like a successful pairing.
For good measure, I then clicked the “Configure node right now” (same Commands tab), and got the same “Command Sent” confirmation.
Lo and behold, my dimmer is now responding and my scenes are intact!
I’m not sure if the “Configure node right now” had anything to do with my success, but I wanted to record my steps for posterity’s sake.
