Not sure if it's the simplest way, but there's a Pi based project called Open Energy Monitor. This can monitor power usage, and it can also monitor temperature too. http://openenergymonitor.org/emon/
Thanks for this, it looks useful (although more so in general than for this specific project).
However it also looks quite expensive: £70 for a transmitter with CT, plus £20 for the Pi receiver module.
What I currently have is a CurrentCost monitor (~£50, with USB interface) which gets data from appliance monitors (~£25/ea). I think this might now be discontinued as a product though.
I've also looked at the new Mi|Home kit [1] which appears to be able to talk directly with IFTTT (which was one reason I started thinking along those lines) but I haven't looked yet to see how FOSS friendly the Mi|Home stuff is.
