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

Bought these specifically to use Tasmota firmware, based off suggestions found on Reddit. Happy to report that all 6 I received on 2/18/2021 all flashed via the OTA method with zero issues. I had to order from a few other brands (some that I have had success with in the past) that I had to return because they came with updated firmware that prevented this. FYI.

What I like most about these WiFi enabled smart electrical plugs is that it has all the features that the others have, plus what I really need is to be able to monitor your energy usage. Very helpful when trying to determine if an appliance is starting to go bad, when you see the energy use increases.

What I was looking for from the Energy Monitor is that it drew power from 10:32:15 to 10:32:23 (e.g. 8 seconds). And then again between 13:32:15 to 13:32:28, and then again between 20:32:15 to 20:32:28. I’m more interested that it DID draw power – when - and for how long - as opposed to how much TOTAL power it’s consumed in a day - which is what this does. E.g. Your computer sucked 20kW today – BAM – it’s got that if that’s what you want. I’ve never lived anywhere with a sump pump before and it’s been running a lot lately. Just looking to be sure it runs ‘sometimes’ without making a trip to the basement every day… I had an ice block of the outlet outside recently, and was probably REALLY close to flooding my basement. Woke up to it running and splashing because it couldn’t discharge with the outside ice in the way. If it’s run for more than 15 seconds… I HAVE A PROBLEM, and that’s what I’m trying to solve. So this is great for what it says it will do… and for that it gets high marks, I probably just read too much into it and will probably have to program my own IFTTT ;).

The functionality, capability, and ease of use are exceptional. Operation, power consumption monitoring, timer setup, et al, right from your phone! The only issue is with the setup and enabling. There is a quick setup that didnt work for me (nor for my friend), and the manual setup instructions are not correct. Through trial and error, got it working. Setup aside, I absolute love these.

I typically dont write reviews, but this is the worst item that I have purchased on Amazon. The 1st one would not hook up to the internet. The second one finally connected to the internet but continually shuts off after 2 minutes even though I have the timer set for 15 minutes. Dont waste your money on these power monitors.

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.

There are a few things I like about these plugs. I liked the power monitoring feature, although the app does not work correctly on my iPad. It did work on my android phone. I did not have any trouble pairing and adding the devices. However, there are two big issues that make these outlets a poor choice for me. First of all, they do not remember the state they were in prior to a power outage. If an outlet is on before there is a power outage, it should remember and return to an on state when the power returns. The same if it is off. These don’t. If the power goes out, when it comes back the outlets are off and will stay off until you turn them back on using either the app or the button on the outlet. This is a problem if you don’t realize there was a power outage and there is something plugged into it that really needs to stay on, like a mini fridge. That’s exactly what happened to me. I had my mini freezer plugged into this so I could track how much power it was using. At some point during the day the power blinked and the outlet shut off. The next day I went out to grab something and all the food in the freezer was thawed and I had to toss most of it. Not good. My Kasa outlets don’t do that, they come back on automatically when the power comes back, and they also will complete scheduled tasks whether or not the Internet is up. These outlets will not. I didn’t think that was a huge deal because I have my Kasa outlets for things that need scheduled tasks to function reliably. But honestly, why pay almost the same price for outlets that don’t have as good functionality? But anyway, having to check your outlets every few hours to make sure they’re still on when you live in an area where there are fairly frequent power blinks is totally a dealbreaker for me.

I bought these to monitor the power consumption of computer servers that run 24/7 to be able to calculate their energy cost. I also used one on a 3d Printer to calculate the cost per print. BOTH just shut off at different times randomly. No schedule on them, they werent linked to any smart home devices, and the app wasnt running. Plus it was in the middle of the night that it happened, so I nor anyone else around was even awake to have possibly done anything with the app or the plugs themselves. This caused my servers to be down for 4 hours. Not only will I not be able to calculate proper energy cost, but I have lost money from the servers being down and the waster filament on a print when the printer was unplugged by it as well.

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.

Nice solid plugs that still work with Tuya Convert for OTA flashing of Tasmota firmware as of 07/01/2021. They are a bit big, but two do fit in a duplex receptacle perfectly. I bought the 4-pack that came as 2/2-packs
