The device has two data interfaces, mini-USB and Ethernet. All configuration of the device must be done via USB from a Windows computer (there is also a freeware Linux utility, and the protocol is documented as well). The Ethernet port appears to not accept incoming connections of any kind, it only makes outgoing connections at intervals to report its status.
The reason I bought the device was its ability to turn the output socket off and on by remote control over the network. I have a flaky system that periodically needs to be hard power-cycled, and this looked like a reasonably inexpensive way to get that capability.
The way the "net" feature of the device works is as follows: You configure a hostname and path to a POST script and an update interval. Each interval, it will connect to the web site configured and submit a POST request with its current status. The web server can then, if it chooses to, respond with "" to turn the power off or "" to turn it back on. So if you're willing to write your own custom server application to log and control the device you should (theoretically) be able to do whatever you want.
By default the device posts its data to the manufacturer's web site and you can create a free account there to view the logged data and (in theory anyway) also control the power output on the device.
There are a few problems with this. The "free" web account only accepts updates from the device every 15 minutes, and it will reconfigure the device back to 15m if you try to set it up faster.Read more ›
It's easy to use, and its many modes give me the numbers I need. Whether I'm looking for watts, peak watts, watts/hour, montly watts/hour, the Watts Up Meter has it.
Only con: it doesn't have a backup battery, so the recorded data is lost immediately once its disconnected.
Excellent Current Wattage, Cumulative Watt Hours, and Max/Min Watts measurement EVEN AT LOW WATTAGE (<5w, <10w) when Amp measurement error increases.
Wattage is furthermore measured 2,500 times per second regardless of how frequently you choose to log. Thus Cumulative Watt Hours and Max/Min Watts figures are going to be fairly accurate regardless of your log frequency.
The ability to position the meter at a COMFORTABLE READ POSITION and fit the plug into tight spots is very nice.
It has a measurement available called POWER CYCLE which counts up each time power is lost/regained, which of course if not accounted for could greatly affect accuracy.
It automatically puts the information into its own built in spreadsheet making my CUT AND PASTE INTO EXCEL easy. Of course it creates a delimited text file for import, too.
Found the meter EASY TO LEARN AND USE, and the software took at most 5-10 minutes to learn.
Most expected values tracked, though most folks will perhaps be mostly interested in:
- Cumulative Watt Hours
- Current Watts
- Power Cycle (which tracks when power went off during measurement).
Others measures: Min/Max Watts, Power Factor, Volt Amp (apparent PWR), Avg Mthly Kwh, Elapsed Time, Duty Cycle, Frequency (Hz), Cumulative Cost, Avg Mthly $, Line Voltage, Min/Max Volts, Current Amps, Min/Max Amps.Read more ›

Just received the unit and was dissapointed.
1) Manual says: Below 60 watts, amps and power factor accuracy degrades, but wattage is accurate down to 0.5 watts. Read more
