I don't know how Herpstats work as I use Helix but if you are going to use a powerbar to get those extra outlets make sure it doesn't have a surge protector on it. According to the booklet that came with my Helix, the surge protector on a power bar can mess with the built-in fuse system on a Helix. Not sure if Herpstat's are the same but thought I would mention it anyways.
