Hi,
 
	I have had my ISY994i (with z-wave) for a few years now.  I was/am attempting to add a new switch, which wasn't/isn't working (another thread coming for that is) - this led me to try and do a Synchronize  /all command.  As it ran, it created a number of "unresponsive device" nodes...  How do I get rid of these without having to do a factory reset on the z-wave dongle?  My network isn't the largest, but it would be painful to have to rebuild it from scratch.  Appreciate any hints I can get!
