Let's start from the beginning.
My reason to measure the power used by my woodworking machinery is the need to understand precisely how much power is needed for every machine or every job, to be able to rationalize the use of electricity, which could mean what things I can keep on together or even, more trivially, if I can use my bench saw together with a shop vacuum while the dishwasher is working. Most important, I would like to know WHAT to turn on and off to stay inside the 3kWh limit.
It seems there are different options, mostly requiring me to forget about data logging.
I guess the most sensible would be to use a multimeter or ac clamp and be content with just the maximum watt absorption, but I'm not sure it would be the best route.
Maybe I could try using something like this
http://www.amazon.co.uk/dp/B015GQOLU2?psc=1 and simply place it in a place I can look at while working, but honestly I would like to avoid looking elsewhere while using a benchsaw :p Also I'm not sure about the precision of such devices.
Ubiquiti's kit seems very interesting, but I'm not sure I can find it here in Italy, I will have a better look into it.
What about a device like this?
http://www.conrad.it/ce/it/product/125444/VOLTCRAFT-ENERGY-LOGGER-4000-LCD-0001-9999-kWh-4320-hIt seems to be able to also log data onto a sdhc, I think it could be a good option for my needs but in general it seems a very promising little object.
Sorry for the link in italian but I think that website can be translated in every possible language

Another idea would be to use something like the Owl or Efergy power monitor, but I'm not sure it would be accurate and handy enough, and I would like to avoid having to care about changing batteries every now and then, even if that could monitor the entire house energy consumption.
I don't know, I will still have to ponder over the whole subject.
If you have any ideas I didn't think about I will be pleased to hear it!
