Yep. It's on a Herpstat 1 now, but I've had it on a 4 or a 2 as well in the past. The humidifier I have has a dial to regulate the humidity itself, so I just turn it all the way up so when the Herpstat tells it to kick on it does just that.
With the Reptichip, you may not need to worry about the room humidity at all.
