Review: Pratique... mais attention il faut qu'il y ai les cables de chaque phase qui soit accessibles pour y passer les sondes.
Review: Update the firmware if you have issues setting it up. For me i.76.058.8 works great. Once I got the new firmware installed everything worked perfectly! Set up MQTT and home assistant auto-configured all the sensors. The current clap wires are really long. I don't see that as a downside just be prepared to do some cable management. Nothing feels practically premium but it doesn't seem super cheap eithe. I would call the whole utilitarian. So far it's been accurate enough for my usage. It's reporting the same usage numbers as my electric company. The advantage is I can see each phase and there's a leftover clamp to monitor a specific circuit. Right now I'm tracking air handler usage but I eventually plan to track down a phantom draw.

## Features

- Monitor "Exported to/Imported from Grid Energy" vs "Solar Production" in realtime
- Track your home energy use in realtime and create the billing information on hourly/daily/monthly basis
- Compare your electricty bill and income of your solar PV system and provide you a detailed report
- Monitor energy flow in two-way (From Grid and To Grid) by only one bi-directional meter
- Open API for perfect integration into your own server or other Home Automation Platform (Home Assistant,openHAB,NodeRED,ioBroker,PVoutput)

*by T***T on 17 July 2025*

I have been monitoring my energy use for over 12 years now, and gone through three companies. This system is by far the best one I have used thus far! Very easy to set up, and great data! I have bought three of these for my three phase house with three phase solar! I also monitor single phase EV, Hot Water and Air Conditioning! I cannot recommend any higher! A 100% fantastic energy monitoring system!
