phillcoxonI have one of the Centameter Owl units and found it to be very, very good.
I haven’t set it up since moving to my new house but it’s very much plug and play and can be up and running in a few minutes.
The thing I really liked about it was that I could turn appliances & entire circuits off and monitor the change in power usage in real time – with updated figures being displayed within a few seconds. I found it really interesting to test various electronic devices in standby mode vs operational mode to see how much power was saved (often not much)
With the main display unit being portable it’s super easy to wander around the house and test areas of interest for instant feedback. Plus the unit tracks power usage and cost each month as well.
Unfortunately I don’t have the USB version – it would be great to capture that data in real time too.
