Works well, easy to install and use
Responsive device, with a decent app and the added bonus that it will integrate with the Ecoflow app (the actual reason I bought it). I bought a separate enclosure for it and wired it into that. Seems to have no problem maintaining a WiFi connection and helps me avoid giving any solar back into the grid.

Shelly 3em
Works as I need it to in the ecoflow app but unfortunately the micro inverter is not working as I originally purchased it for but the shelly 3em is functioning correctly.No need to purchase the expensive one !!

Worth the money and their TECH Support Team are EXCELLENT.
It does what it says on the box and for the price is good, HOWEVER, this is now a discontinued product by Shelly and isn't available on their website. You can still get support BUT they do recommend you go with the EM-63W Gen3 (W for Wired or T for Tag I think), however you can also use Shelly EM Gen3, Shelly Pro EM-50 and Shelly Pro 3EM-120A and purchase a 50amp CT clam for about £10 rather than using the big bulky 120amp ones! Also got it connected to Home Assistant and the Shelly Mobile App.

Cheaper than buying through Ecoflow
Used to communicate with Ecoflow Stream Ultra. The instructions are as clear as mud but once I had worked out the wiring and WiFi it was great

Works well once I got it wired up
This Shelly 3EM needs to be wired into your main electric distribution board so it really needs a qualified electrician. Once wired in it works well and gives you a lot of information. I'm using it with single phase and so I can monitor up to 3 power feeds. I've also paired this with an Ecoflow PowerStream and the Shelly helps to automate the whole system. Very good product once you get it wired in.

Accurate energy monitoring.
This smart meter works with the Ecoflow stream solar battery system, allowing accurate monitoring of energy usage through Ecoflow and Shelly apps and allows Ecoflow to regulate power preventing grid feed-in. The device makes it easy to identify wasted energy and save money.

Shelly just works......
As always shelly does it again. Works well once paired via shelly app. Works in tandem with ecoflow stream. The good thing is you can use normal two wire power cable with plug on the end and works fine. No need to add to fuse box.

The perfect "missing link" for Home Assistant integration
Despite shipping from Germany to Australia, this arrived much faster than the estimated date. It has been the "missing link" for my home setup, allowing me to monitor my solar and battery circuits without needing individual plugs for every appliance.The Highlights:- eamless Setup: I had an electrician install it (as required in AU), and the process was quick. It adopted to the Shelly Cloud immediately and integrated into Home Assistant without any fuss.- Highly Accurate: The consumption data is spot-on. There is only a very slight delay, providing what is essentially real-time monitoring for three separate circuits.- Solar Friendly: It’s been perfect for tracking our total energy flow alongside our solar and battery storage.Verdict:If you want a reliable, hub-free way to get professional-grade energy data into your smart home dashboard, this is it. Fast, accurate, and incredibly easy to automate.

Buen dispositivo, instrucciones poco intuitivas
El empaquetado y envío correcto y rápido, el equipo una vez configurado funciona correctamente y es bastante acertado en cuanto a precisión de la medida.Trae tres pinzas de 120A, la instalación es bastante sencilla, pero hay que tener un mínimo de conocimientos de electricidad para instalarlo.Las instrucciones tanto para instalar y sobre todo, para acceder y añadir a algún sistema domótico, son muy poco intuitivas.La aplicación de Shelly, imprescindible para configurarlo en Shelly Cloud, me dio varios errores y se congelaba constantemente, ahora parece funcionar bien, pero me costó añadir el 3EM a la aplicación.Ojo, porque parece que va a ser discontinuado porque ya ha salido el EM3 3 gen y este ya no aparece en la página oficial de Shelly.En mi caso para añadirlo como meter a un sistema solar de balcón, tenia que ser este modelo.Para añadirlo a la app de Shelly, antes hay que acceder a la wifi que crea el dispositivo, buscando la Ip del mismo que es la del “router” de la wifi, después configurarlo para que se conecte a la wifi doméstica, (ojo, que una vez configurado solo será accesible a través de la wifi doméstica y de la ip que está le asigne), después añadirlo a la app de Shelly a través de la opción “escanear red” poniendo tu red doméstica.Y por último añadirlo a tu sistema domótico… nada intuitivo para personas sin unos conocimientos mínimos.
