Review: Super Useful, Informative Product - I bought these smart plugs to make my office run more efficiently. Using these smart plugs, I can schedule my office equipment to turn on and turn off at certain times of the day so that during the closed hours, I am saving energy. For that purpose, these smart plugs, work flawlessly. In addition to being able to schedule on and off timing, they also show the power usage going through them. It’s a little unclear in the app (there are no units shown), but I believe that the numbers presented are in kilowatts. So, the plugs, via the app, show how many kilowatts the plug is being presented and it tracks that power Usage both real time as well as on a daily and monthly basis. I wanted to be able to see how much power my office equipment was using, and these smart switches provided the exact amount of detail that I needed. Finally, and it’s a small thing, but these smart switches fit height wise, two into a standard AC outlet. This allows me to put two of them into a single outlet. Some other smart switches that I have tried take up more space on the outlet preventing use of the second outlet thus wasting outlet space. So I was very happy that I was able to put two of these into a single outlet. Overall, I’m very happy with these smart plugs and would recommend them to anyone that was interested in having a smart plug that was both schedulable as well as provided real time in historical power usage information.

Review: Great unit for ESPHome - Love these! Easy to use and Compatible with Flashing over to ESPHome for Home assistant. I do wish it was a bit easier but if you do a lot of these can just make a jig to program. Power monitoring seems to be accurate checking with a Kilowatt The inside traces seem to be thick enough to handle the amperage it is rated at. Function great for my needs to monitor energy of devices and trigger automation and also be able to toggle on and off the device. Use with my Washer to tell when it is done since it can do 15 amps.
