Monitoring various branches of my inverted AC outputs to various appliances. Works great and is very accurate. These measurements are logged on charts for historical monitoring. Easy install and no programming needed.

Excellent product and easy installation. Allows me to monitor a remote condo and keep tabs on the HVAC and power consumption. The app is well polished and provides all the information and control you would expect with this device

I use this to monitor a 30a feed into my garage shop. As is the case with every other Shelly product I own, this one was also excellent build quality and easy to install. The only gripe I have with Shelly is that that make the terminals just a tad bigger, sometimes you have to hold your tongue just right to get your wire in there. Easy to set up in home assistant and pull data into my dashboards. Solid product!

Outstanding piece of kit. WiFi and wired Ethernet, web, JSON, Matter, Modbus and more all built in. Mine worked right out of the box. Got ic controlled via the web and MODBUS TCP. Handy device priced right.

Great product generally, although there are a couple issues with the REST API if you're trying to write your own code to control it. Bad SSL certificate for https, and it rejects https requests anyway with a 443 error, yet it also does a strange redirect to https when you call http on port 80. I tried updating the firmware but issue remains. Integrated with HomeAssistant and called that API instead, which works great. Would be 5 stars if not for the odd issues with restful calls.

Easy to install and does what it claims to do..

I love it. Definitely is the amazing device and so easy to install. Perfect size. The connectivity is so great.

Works great, has a built in access point for easy monitoring & configuration. Modbus TCP interface works fine with my SCADA system. Seems accurate

Monitor e registo de consumo, voltagem e corrente, permitindo IoT, exporta CSV, para mono, bi e trifásico, incluindo crédito de sistema solar (registra produção). Muito versatile e compacto. Qualidade e precisão TOP

Ottimo prodotto, richiede un minimo di impegno per l'installazione. Peccato solo non ci sia né nell'interfaccia nè nell'app cliud un indicatore della massima potenza consumata. Sarebbe molto utile. Usato per monitorare sia il consumo totale che quello della linea cucina di casa.

Fácil instalación en el cuadro eléctrico, viene con 2 pinzas amperimétricas. Yo no tengo mas productos de Shelly, así que no puedo opinar sobre la integración domótica. Lo uso para el monitoreo de las placas solares. La app te permite monitorizar en tiempo real el consumo de energía de la vivienda, la producción de las placas solares y el volcado/consumo de red o baterías. Gráficas diarias, por mes, año, etc. Funciona con la wifi de casa y te da información suficiente y bastante exacta sobre tu consumo energético en cualquier momento y lugar. Solo encuentro a faltar en la app, disponible en apps de otos medidores (y otros precios), el diferenciar el consumo por electrodoméstico. De momento sin problemas de funcionamiento y satisfecho con la comprs.

Fonctionne parfaitement avec home assistant

Funciona perfecto y es super útil para el monitoreo de todo el cuadro eléctrico mas 2 cargas. Tambien lo he usado para monitorear motores trifasicos, es genial!
