Ahhh... it sounds like a firmware bug in the VCM then - I hadn't noticed the clicking before, and mine was doing it while charging. I'll keep an ear on it and see if it keeps up with further use.
Big concern is that I don't feel like I can comfortably keep the app running while I'm watching it from upstairs... sometimes I leave the app open for hours so I can glance over at it (like tonight, trying to cool the battery). I guess there's not much you can do if there's no way to see if commands are triggering the relay from the programming side...
