POFET Smart Meter Energy Monitor WiFi Electricity Usage Monitor 80A Compatible with Tuya Smart Life

I wanted this to monitor accurate historical energy data and actual live data for our new heat pump.The device comes with a CT clamp but no other wiring. So I brought a small in-line fuse carrier and some 1A fuses from Amazon and connected it into a spare way in a connector block on my side of the meter in my meter block (see picture). I’m an electrical engineer, so am comfortable doing this but wouldn’t recommend it’s done by anyone without electrical experience. It should be a very quick job for an electrician though.The CT clamp has a diameter of 10mm so it may not fit some meter tails, but worked fine on the tails going to our heat pump.Set up is super easy on the Tuya Smart app and readout is good. Just be sure to turn off the 5GHz on your router while you pair, or it won’t be found. You can turn it back on straight afterwards.All in all I did everything within half an hour and am very happy with the results

Excellent. Just what I wanted. Easy to set up. Unit placed in plastic box and connected to mains supply via standard 13A plug with 1A fuse installed. Readings match my measurements and appear accurate.With reference to a previous review, power reading will only equal voltage x current when power factor is 1. John

Do not buy!First issue is the CT Clamp is not large enough - see pic - so won't clamp around standard incoming electricity tails.Second issue is it's just not accurate, (holding in place) the device was reading 100w yet my Electricity meter was showing 0 (no grid power because I'm running on solar/batteries) . Pointless

Worked first time. Excellent price

Installation was pretty simple. You will need a 2 core flex and a plug. Along with precision screwdriver to wire it up. The instructions are quite dire and in Chinglish.But it’s relative straight forward and if you can wore a plug you can wire this. I would recommend putting a piece of insulation tape over the screw holes where the L and N enter just to make it a bit safer although the screws are quite recessed.Once physically installed you will need to download the Tuya app. I already use this for my smart plugs so that wasn’t sure h a big deal. Then you simply press the button on the front and hold for 5 seconds until the blue light is flashing. Then go to discover it via the Tuya app.When it discovers looks like a universal adapter with a Chinese description. So rename it when you can.Then you are pretty much ready to go. I wanted this to monitor power consumption in the house so it’s clamped to the live wire feed into the consumer unit.It seems to measure consumption quite accurately however the app has some serious downfalls hence only 3 stars.You cannot add a unit price to electricity so you can see how much you are spending in real time. This is such a shame.You cannot set alerts for going above a certain kWH usage. This is a shame as I don’t want to be looking at the app all day, just want to be alerted to spikes.There is no granularity of time measurement - eg. By hour or minute. Just by day/week/month. Again this is such a shame.Overall the device works, although setting up is all a bit heat-Robinson but the app really sucks and ruins the whole experience.

Smaller than I expected. Easy to install assuming your a confident DIY person, just need some mains wire and plug. It does leave mains voltage metal exposed so you will want to enclose it or install it somewhere safe.

This the power monitor is incredibly capabale a d great value for money. The app looks awesome, thank you!

Breeze to fit but very disappointed in that the actual watts reading is not correct, the voltage and current readings are correct ( measured with clamp meter) however basic V x I = watts . This is not the case every time it is low, ( approx 40 watts lower than what my smart meter is telling me) am I missing something here or is it just badly calibrated. Any help please.
