I have had several brands before, and this one takes the cake, hands down. It measures much more slight power draw (1/100 w precision though I haven't tested a minimum), and displays so much on its clear screen or in the app. Plus it's not emphasized much in the description that it is also a wifi switch! Yes, it has an on/off button on both the device and in the app. It does everything but make coffee. And it can be made to do that. It takes about .5w with the switch (relay) off and 1w with it on, so a bit more than a standard wifi plug, but not much. Display brightness seems to have a minor effect on the power draw. It has several different display screens, all of them providing lots of information. It works without wifi, too, as all settings and features seem to be available on the display. Oh, and it uses the popular Tuya / Smart Life app. It does require about 10 secons to boot up.

I have Kill-a-Watts, and they work just fine with the caveat that they don’t have a smart feature. I was looking for something I could track my wall A/C energy usage with. A huge plus, this unit is not only smart, using the Smart Life app, but it’s also rated for 265v 50/60, and 16a. My A/C unit requires 250v. I just needed to get a 6-15p to 5-15r adapter to go between the wall and this unit. Then get a 5-15p to 6-15r (I got the Plugrand 4-in-1) adapter to plug the A/C into this. It works perfectly!As others have said, the manual lacks a lot. The E_Test app they suggest is meh. Get yourself the Smart Life app, connect to this unit, and you’ll be golden.

WIFI stopped working. Worked fine for 3 months, then poof, WIFI gone. There is a big red X next to WIFI on startup. It is not because the WIFI is not available.

Very bright and clear display! Use of the wi-fi feature requires registration of household wi-fi password. I suppose I should have known. The manual is four small pages of ~4 point type, written in Chinglish and an alternate four pages of straight Chinese.The unit offers three broad functions: 1) Basic one-outlet power monitor which works very well. 2) Remote "smart switch" via wifi & extra app which is functional. 3) Remote power analysis and control via app which is poor. Limited wifi range. Offers programmable over-voltage and over-current protection.Outside Tuya app does sync with this unit, but there is NO manual. Graphing function only reads in ONE HOUR intervals!

I got this WiFi-enabled watt meter to keep tabs on my home appliances’ power usage, and it’s been a handy tool for the job. The plug-in design is straightforward—just pop it into a US socket, connect your device, and you’re set. The large, backlit color display is a big win; it’s easy to read voltage, amps, watts, and energy usage (kWh) even from across the room. I’ve been using it to monitor my space heater, and the numbers update in real-time, which is great for spotting power spikes.The WiFi feature is what sold me—it pairs with an app (setup took about five minutes) and lets me check stats or set timers remotely. I’ve got it on a schedule to cut power to my coffee maker after an hour, and the delay-to-restore function is clutch for avoiding rapid on-off cycles. It also tracks electricity costs if you input your rate, though I found that part a bit fiddly to set up. Overload protection kicks in at 1800W, flashing a warning if you push it too far—tested this with a hairdryer, and it worked as advertised.It’s not perfect, though. The WiFi connection dropped once during a storm, and I had to reconnect it manually. Also, the app doesn’t log historical peaks (like max wattage over time), which would’ve been nice for deeper analysis. Compared to a basic watt meter I’ve used, this one’s extra features justify the price, but it’s overkill if you just want simple readings.For anyone into smart home gadgets or energy monitoring, this is a solid pick. It’s ETL-listed, feels durable, and delivers on its promises. I’d give it 4 stars—losing half a point for the app quirks, but rounding up for the versatility. Just make sure your WiFi’s reliable!

Lots of features with WiFi connectivity… eye opening smart meter tells you how much power your device is drawing

Worked perfect, nice. Information but power consumption and billing rates are confusing.

Anything over about 2kw (20 amps x 120 volts = 2400 watts) triggers the automatic cutoff.As long as one is operating w/in 2kw, it works as advertised but spikes take it offline. I suppose the Chinglish instructions cover this, but it took me awhile and some trial-and-error to figure out what was happening and how to recover.Bottom line for me, though, is that this device is not up to my task of monitoring my standby generator's load because it disconnects the generator before the load reaches the gennie's limit of 4 kw.
