OWON 3 Phase WiFi Smart Home Energy Monitor, 3 Phase Clamp Meter with 3 200A Circuit Level Sensors Vue Real Time Electricity Monitor Meter Smart Life Energy Monitor

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.

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....

Although the equipment seemed to be working it failed to connect with the wifi after many attempts. An email to the supplier was not answered and their telephone seems to be disconnected. I have no option but to return the equipment.

Edit: I have many of these. Occasionally they break.They don't work very well with Tuya after a firmware update has wrecked them.Until they've fixed the Firmware I won't buy them again. Doorstops right now.So far they connect and work.Connection can jump in and out, but this may be more that it is in low wifi power areas.Basic, but well priced, works with Smartlife/Tuya and gives power factors.It can be used to automate electricity efficiency at night etc and know if large machines still running.Smartlife has access to weather info so it's possible to link it to outdoor weather too.Not sure on accuracy, but hopeful it's ok and will compare side-by-side on MID meter.Power/Voltage 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.CTs are clip on and have sockets and really good.
