TOPGREENER TGWF115PRM Wi-Fi Plug with Energy Monitoring, Smart Outlet, Control Lights and Appliances from Anywhere, No Hub Required, White, Works with Amazon Alexa and Google Assistant - Amazon Vine

I bought this primarily to turn on and off pool pumps as well as monitor their energy usage. When I dove into the statistics for energy monitoring I saw my pump is using 2012 mA. That’s 2.012 amps. Volts is 121.3. We know that V*A=Watts. 2.012*121.3 is 245.14 watts. Watts on the app says 146.4. (See pic) So, one of these values is incorrect. I contacted the manufacturer and they said “Currently something is wrong with the calculations, we are working on a solution. I apologize fir the confusion” It took them 2 days to even respond. I have no idea if the kWh is correct since I’m not sure if is based off of watts or volts*amps. I don’t know if any of the numbers are correct since the math says they can’t all be correct. As for the on off functionality it works pretty well. I can control it from my phone. It’s really unfortunate that the energy monitoring does not work though since that’s half the reason I bought it. I can turn my pumps on and off from anywhere though.

The device feels plastic and cheap but its only the exterior feeling, the device seems to be a very robust one and works almost perfectly, the app is the only downside to it, its just another one of those tuya apps, if you recognize that name, then you know what I am saying, is a copy paste of another apps, and it feels a bit empty on some areas such as the power meter side, but it gets the job done, I wish they would put a bit more effort on the app and expand its capabilities, I am sure it is possible to do it though an app update, and it will greatly improve the possibilities and potencial of the device

I had attached this to an insta-hot water dispenser, first left the smart plug remain on 24/7 for a week to obtain a baseline of my hot water dispensers energy usage, then I set it on a schedule to eliminate 10 hrs out of the day, when I wouldnt be needing my HW dispenser and I saw a ±20% reduction in the energy use, so the energy tracking of this smart plug appears to be working fairly accurately. The insta-HW dispenser has a pretty high energy demand to heat/maintain the water to 180°F, so this smart plug is capable/rated for high wattage devices. Highly recommended!

Got them working with my Android phone in less than five minutes. For each device you get to see milliamps, Power in watts, voltage and total kWh. By default the devices are switched off when the power is connected so a power outage will leave all of the devices off. Their technical support showed me how to set up an automation in the app so that if the device is switched off, the app turns it on. One other con: If you click on a device and select statistics, you only see the current month.

There is no way to export the energy usage data from the app. This would be fine if the outlet group option could let you see the energy usage for all of them at once, but you can only see the energy usage chart of a single outlet at a time, as far as I can tell. Also, you cant really drill down into the data at all. You only really have 2 views of the data: current, and by day/month. You cant even select custom time ranges from what I can see. This is all really too bad, since the rest of the app is designed really well, specifically the automations.

I got the two pack of this on a deal. it came out to about $20 each. I like that the set up was easy. The feel of the product seems sturdy and heavy duty. I like that it is 15A and I can run a small space heater on it during the winter. I use it to turn on a lamp in the living room while I am away to let people think that someone is home. The only thing I dont like about it is the size. It is much bigger than I thought it would be. I can see how its size would be a problem if the outlet is near furniture. But once you put it on the wall, you leave it there and you dont think about it anymore.

Setup can be tricky on these, often requiring the second or third try on the app before the device successfully pairs. Once they are paired, they work rock solid and Ive yet to have any issues requiring resetting these devices unlike other brands of Smart Plugs Ive bought in the past. Being able to monitor energy usage is very useful, as I like to monitor how much power Im using with my space heater and certain other appliances in my apartment, and this device has been fairly accurate at providing those readings. It integrated with Alexa with no problems.

I love these, I can View energy usage, turn appliances on and off, set schedules and timers.. all from my phone. I can now control appliances at my house like coffee pot, electric blanket, patio and light stringers in a way I couldn’t before. Can now set my coffee pot the night before, and set to turn off my sons entertainment center in the middle of the night every night, he often falls asleep with it on. Definitely makes my home more efficient. Definitely recommend.

On iOS at least the app for this sucks. Setting up is a pain. It constantly asks you for location services (and makes it seem like it requires it but I was able to set it up just fine if I kept clicking ignore). Trying to put in Wifi was horrible, I needed to switch apps to copy and paste my ID and my password but as soon as you move away it resets both fields. It also has not been updated in at least a year so on iOS it has no App Privacy Labels so it is unclear exactly what the app itself is doing. I just limit what data this app has, I dont have it connected to any other smart home devices since all I needed to do was see my power usage. Which once you get setup, it works fine. But the setup portion is the worst I have seen for any smart home devices.

I use Home Assistant and prefer flashable devices that I can control locally with installing vendor apps or having network traffic round-trip to the public internet to control a plug sitting right next to me on the same LAN. These flashed Tasmota without issues using Tuya-Convert running on an old Raspberry Pi 1 I had lying around. To save someone else the trouble, here is the required Tasmota template: {NAME:TGWF115PRM,GPIO:[0,56,0,17,134,132,0,0,131,57,21,0,0],FLAG:0,BASE:18} I have not yet fully calibrated the energy usage yet, but did set the voltage using the VoltageSet command on the console. There is a page on the Tasmota Github site on power monitoring calibration for those interested. I am thrilled about the value of these devices -- they are as inexpensive as the Sonoff Basic but do not require soldering headers to flash or cutting power cords to install. Flash OTA; Plug; Play!
