Looking for AC current/power logger
Finderbinder:
There are countless amount of simple devices which logs/counts energy consumed per time unit (day or hour at best). Basically all of them works by the same algorithm as I suspect (they are clones of clones of copies of...).
But I didn't see any logging current/power at desired time intervals (ms, s, min).
Its purpose would be to understand the specifics of device's work just by looking though trends (not physically sitting by the device and continually watching long process).
Device with integrated AC socket for device under test and logging to memory card or USB media also triggering would be the best solution.
Tjuurko:
All the power meters I saw issued the measured parameters (U, I, P, F, PF, T) through the serial port (9600 8N1) one time per second.
This port can be immediately connected to BLE.
The data registrar can be any "Raspberry Pi", she will be binding data to the current time.
TomKatt:
We've got a Fluke 435 Power Monitor at our plant that does that kind of thing. It's a bit of very pro kit with a price tag to go with it, but you probably don't want to be holding a Uni-T when you're measuring 3 phase feeds with 100's of KW power :P
But, same idea.

Good Morning Finderbinder, there are plenty of multimeters with logging capabilities. The one I use most is the EEVblog121GW, which can log to a micro SD card and the results transferred to a spreadsheet to see trends. Also the sample rate is programmable. Google it and look at it's specifications and you will be impressed. (10 Amp max.) :popcorn:

How do you measure real power (energy consumed per time) using a multimeter? Unless the meter specifically supports measuring real power, like the Gossen Metrahit Energy series. Does the EEVblog121GW support that? I don't mean the apparent power you get from multiplying RMS voltage with RMS current.
