Shelly Pro EM 50A | Wi-Fi & LAN Energy Meter with Contactor Control | DIN-Rail | Home Automation | Bluetooth Gateway | Compatible with Alexa & Google Home | No Hub Required | Power Monitoring

Very easy setup either ethernet or wi-fi. Current readings and voltages match closely with my Fluke DMM. I am still experimenting with all the available features. The desktop and Android apps have both worked well. If you are interested in power consumption with the ability to control the load I would consider this item.

Worked perfectly for monitoring a 50a 120/240V panel in a marine application

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.

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.

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

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.

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.

A fantastic bit of kit. Allows me to control a contactor to remotely turn my hot tub on and off overnight on cheap rate electricity. It also feeds the current power usage into Home Assistant via the Shelly integration. Couldn’t ask for more!

Item worked as described.

I had to have the electrician come back as the clamps that go onto the main are hard coded to incoming or outgoing power. I don't know why they built it that way as the signal clearly comes through just fine either way...just negative when it should be positive. It's great to know how much power I'm using and it was very quick to setup with home assistant for automations based on power usage. I've paired it with some outlet meters from Shelly which are working great to know if I'm actively sitting in the office based on power usage for some useful automations.
