Not blind at all. I spent hours looking for something ready to go out of the box, we just don't have it. They are mostly geared to measuring the draw from household devices. Can't confirm but I think all of Europe is 220 V and 50 HZ, so 1 meter to rule them all sort of deal.
Where as we have 110 to run most house equipment, and 220 available for appliances with a larger draw. (Dryer, Furnace, Stove).
I had found a few youtube videos previously for a DIY project, but I put that on the backburner last year. I recently started looking into it this week and am putting together a parts list. Depending on the quality this will be somewhere between 40-120 CAD for me to put together. I linked one I found below for a build. I want to go thris route because gear is pushing well over 2000W these days, so something robust would be nice.
I'm just waiting to see if I am going to buy a PDU with the capability first, haven't heard back from the seller in a few days. They're just so darn expensive to ship.
