Fiable
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

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.

Shelly 3EM + EcoFlow PowerStream
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.
