Sorry, I thought I was clear when I said to reset the device and let Hubitat detect it again. I learned the hard way not to remove it. I have had to reset devices, so I have had to do this more than once to get a device that has gone AWOL to respond again. Fortunately, that has become a very infrequent event. It is a handy tool to keep in your mental tool box for those occasions when it might be needed or useful.
