Oh, the humidity of it! in Ollie Modifications Posted December 31, 2018 I've also bought the WS-3000 system with eight remote sensors. We've set it up around the house and it works very well. I hadn't realized that the console wasn't designed for wall mounting -- it has a base for standing on a flat surface. More importantly, the console is powered by a 110V adapter -- not by battery. The adapter outputs 5VDC and someone on this forum (I think) suggested that it could be replaced by an USB to Barrel Jack cable, thereby allowing the use of the Oliver's USB outlet instead. I'd like to do this but the cable I ordered has a Barrel Jack that's much too large and I can't seem to find a source for a suitable cable.
