I haven't tried that but it looks to be an updated version of the Herpstat 2 which is what I use. It is generally very good and I'm glad to have it. It does have some issues with the halogen bulb flickering during ramp up/ramp down but otherwise does a nice job. The programmability is very good. The remote monitoring of the new one might be a nice feature to have. I may give it a test one of these days.
