Our electric utility recently replaced our meter box with a digital one that somewhat magically sends its data back to the mothership. The cool bonus of this is that we can track our energy usage along a number of metrics. The online monitoring application isn’t super-sophisticated and I’d like more flexibility in how it aggregates data, but it does give us a window into how we use power. Not surprisingly, our usage increases in the morning, evening, and weekends. But what we hadn’t expected to see was just how much the usage spiked when the hot tub timer switched on. Turns out it’s a whole lot easier to not be “hot tub people” when you can see just how much power it’s using (and money costing).
