Shelly 3EM | 3-Channel WiFi Smart Energy Meter with Contactor Control - 120A (per channel) | Compatible with Alexa & Google Home | Remote control iOS Android App | Solar/Net Metering | No Hub Required

Whilst this is a 3 phase meter, it is equally happy on a single phase system - just link all 3 inputs together. It's very easy to install, but does require a 240Vac supply - easily found if it's being installed into a consumer unit. Wi-fi connection is simple enough but will require a smartphone/tablet/laptop etc to get it set up. The Shelly app works well and keeps a log of energy usage for its own graphs. The meter also understands the concept of feeding energy back into the grid (PV etc). This model can also be integrated into the EcoFlow system to control the output of their PowerStream micro-inverters to maximise the usage of "home grown" energy before taking expensive units from the grid. It works well in that respect.

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.

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.

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 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 !!

If you have a powerstream the shelly will allow you to get the true grid pulled watts and you can get rid of all the powerstream plugs ,allows automations with powerstream . this is a must .

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.

Monitors energy consumption brilliantly, I bough this as it is now compatible with the EcoFlow Powerstream, no more need for smart plugs, this device monitors whole house consumption and lets the PowerStream micro inverter know what to feed in to the house.

Perfekt

Retourne la conso precise de mon cumulus, quasiment en temps reel. Integration a home assistant tres simple. Il m’a aussi remonté un re tour de phase sur mon reseau elec dont je n’avais connaissance. Bref du bon matos

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.

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.

Ich bin absolut begeistert vom Shelly 3EM. Das Gerät macht genau das, was es soll – und das zuverlässig. Besonders praktisch finde ich, dass ich alle drei Phasen unabhängig überwachen und steuern kann. So habe ich jederzeit einen klaren Überblick über meinen Stromverbrauch und kann gezielt optimieren. Die Einrichtung war unkompliziert, die App ist übersichtlich und die Verbindung über WLAN funktioniert stabil. Besonders gefällt mir auch das Design: kompakt, modern und hochwertig – es fügt sich perfekt in meine Installation ein. Für alle, die ihren Energieverbrauch im Blick behalten und intelligenter steuern wollen, ist der Shelly 3EM eine klare Empfehlung.
