Wattson Energy Meter Additonal Sensor

Customer Reviews

We weren't sure if we needed an extra sensor or not, so we bought one. It turned out that we didn't, but It Must Be Green said we could return it anyway. I wish we'd spoken to them before hand as they really seemed to know what they were going on about (well, a lot more than we did anyway!). As it is we're really happy with the Wattson device, we have trained it to glow blue - or I suppose it's trained us as we now use less energy than before.
