Wattson & Holmes

We've had the Wattson at home for a while. Using the Holmes software (subtle naming there!) I can view our household electricity usage over the last few months. Holmes may be in beta, but it makes lovely graphs.

We've been glad to find that our "resting" power consumption is quite low, even with the server running. You can see the kettle boiling and so on in the morning, and the washing machine (ouch!) in the evening.

Our consumption goes up when Michael stays at home with a cold, boiling the kettle and running extra computers...

We can also spot the weekends when we are at home more, and more likely to be running washing machines and so on:

It's very interesting to see how our power usage varies over the hours, days and months. I look forward to the winter to see how that changes things!

(Aside: I recently read Arthur and George by Julian Barnes - a fascinating book. I'd recommend it to all those who like the naming of Wattson!)
