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

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.

Fantastic current meter! The bonus is built in Ethernet! Small size will fit in tight spaces and easy install. Great function, except for some reason data download is not working right. There is also connection point for 1 more CT, but last I checked it is not sold separately. AND I wish there was short piece of DIN rail in box.

Worth the value, high quality and reliable

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.

Excelente!

Works great with Homa Assistant. Have 4 of these 2 are on wired ethernet and 2 on Wi-Fi. Not 100 percent accurate but very close. Wish there was a offset or calibration process. Note the voltage input is very small and somewhat difficult to connect. Home Assistant immediately identified the devices on the LAN and came online without issues. Entities include power W, Aparent power va, current A, Power Factor, Total active energy kWh, Total active return energy kWh, Frequency Hz, and Voltage. Also can reboot the device from Home Assistant, control the relay dry contact and update the firmware in the HA interface.

Este medidor es asombroso. Puede mostrar el rendimiento detallado de las instalaciones y lo vemos en nuestro celular!! Super recomendado

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.

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!

Works great and integrates easy with HA
