## Description

OWON 3-Phase WiFi Smart Home Energy Monitor with 3x80A Circuit-Level Sensors - Vue Real-Time Electricity Meter for Smart Life : desertcart.co.uk: DIY & Tools

Review: It works - Needed to monitor 3 phase power usage in an office building and this works great. Connected to our WiFi via Smart Things app, so can keep am eye on power usage from my phone.
Review: Data works again - can use for large scale metering & control. - Physical: These measure voltage (and its power supply) on one set of wires that need a <10A MCB 3-phase supply and then current is gained using the CTs that clamp around the cable you want to measure. (NB. if this is confusing then avoid messing with 3 phase power). The voltage/supply cable a bit short so it's often a job to connect it to an MCB AND put the CT's in a good spot, but having an external aerial helps greatly to get the the wifi comms outside of a metal distribution board. The CTs are clip on units also with plug in sockets - they are really good. Ok, so they should be useful to log data about the power use and send the data somewhere... So these units can work with Smartlife/Tuya (rubbish graphing) AND Home Assistant (which is very good) to give power metering and logging very easily on 3 phase supplies and equipment up to large current. HA can also respond to things drawing power and do various automatic actions on other equipment. I have many of these meters and they are a very good value electricity logging unit. It's even possible to use remotely at another location (with wifi) and check what is happening in power use - say at a remote site. Data issues: It was a battle to transfer data onto other platforms out of the units directly or out of the Tuya cloud... Previous to the end of 2024 the units had a local IP port open 6889 which was very handy. Then they shut that off with a firmware change so they didn't work with localtuya in HA. One could only could use the smartlife/tuya app. Not good! Jan26: I found it possible to use the Xtend Tuya integration for Home assistant to be able to pull data from Tuya (graph attached). Hooray! Having lobbied to fix it over 2025 I'm a touch sore that there was extra work (and downtime) caused by a firmware change that they wouldn't reverse ... BUT at least they operate now by a different route. The smart life/tuya app is ok and has worked all along but the graphing is pants. General: Connection can jump in and out on odd units (say 10%), but this may be more that it is in low wifi power areas. Sometimes they need a reboot which is a pain. About 5% (1 in 20) of them have failed completely over 2 years so a fair reliability record. Accuracy is ok, compared side-by-side to a 3-phase MID meter. Better than Emporia v2 (the other alternative) at finding reactive v. active power. Emporia units have better ability to do a whole distribution board if single phase 50A, whereas these are far better for heavy duty 3 phase if you can overcome the problems to access the data.

## Features

### ⭐⭐⭐ What's the point of Bi-Directional CTs if the Software doesn't log the data??
*by M***B on 21 November 2023*

The 3-phase wifi Energy Monitor would be an excellent piece of kit, worthy of 5*, if it wasn't for the fact that despite the CTs being Bi-Directional, the Tuya App only logs the Energy as a positive figure, even though it dispays the Power as a Negative Figure in Real-Time. Also, the software doesn't log the total energy over a 24-hour period, nor does it log the Peak Power or Minimum Power detected, nor does it show a Graph of the Negative Energy detected by the bi-directional CTs. If you're the manufacturer of this produce, there's a lot more you could offer from this kit, since it's detecting everything that's required in terms of bi-directional data logging, peak logging, and total energy logging. This is a lazy attempt at a wifi data logger. Is there any way to hack the data to have it sent to a different destination, to allow proper analysis of the logged data?? Please advise....
