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

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.

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 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.

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.

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!

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

Good quality product

This "PRO" line Shelly Energy Monitor is kitted with a pair of clamp on 50A inductive sensors. My 100A breaker box is tight for a "Sense" or "Emporia" whole home sensor, so this Shelly device works well for monitoring at the appliances I want to move off of "peak electricity hours". Long term I may move the sensors to different circuits in my breaker box, but for now this monitors and controls a relay at the water heater with no neutral in a DIN rail box. Using WiFi now, but ethernet connectivity removes all the WiFi points of failure. Ethernet and DIN format are main reason to go with this Shelly "PRO" device, which is due for a processor / platform upgrade not supporting Matter etc. Adds to HomeAssistant w/ no pain. Using Shelly app logged into the Shelly cloud I had it immediately provided daily/last 24 hour energy consumption charts etc. If not familiar with the Shelly ecosystem, several clamp on power monitoring devices are available. Power monitoring devices require a voltage reference, while clamp on current meters are simpler and safer.

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.

Gutes Gerät. Shelly Qualität. Ohne Cloud und App problemlos nutzbar. Und wenn man es hat: In Home Assistant problemlos intigrierbar. Der LAN Anschluß sorgt für eine problemlose Verbindung. Einziger Nachteil: Der Einbau ist nicht für den Standardheimwerker möglich. Ich müsste mir einen Elektriker kommen lassen. Der hat das aber unter einer halben Stunde eingebaut bekommen.

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.

In goede staat ontvangen, hopelijk maakt hij zijn verwachtingen waar. Nog niet in gebruik genomen vermits ik een ander Pro EM120A (Amazon.DE) niet heb mogen ontvangen :-(. Deze zouden samen geïnstalleerd worden, vandaar nog geen indrukken.....afwachten.
