Shelly Pro EM 50A | LAN & Wi-Fi 2- Channel Energy Meter with Contactor Control | DIN-Rail | Home Automation | Compatible with Alexa & Google Home | iOS Android App | No Hub Required | Power Monitoring

Works exactly as described and been installed for 5 months without problem.

Reliable and Consumer Unit compatible. Fitted multiple units and have had perfect reliability and good accuracy for last 6 months.

I connected one ct clamp to live power in from grid and one to live power in from pv out to grid , I put a plug on mains supply , Works great and seems very accurate . This is one of the best I have tried with a very good app on tablet and phone

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!

Added this to monitor two circuits within my home to give me more granular power consumption, works perfectly with the Shelly Home Assistant integration. If you have a bus bar within your distribution board it will probably obstruct it which will mean either cutting down the bus bar so you have free space at the end or installing in a separate box as I have.

Works very well with lots of information to view and log, unfortunately it was not compatible with other equipment so I had to return it but that no detriment to the Shelly

Using this to monitor incoming power and also EV charger power, Home assistant is outputing 2 graphs showing house usage without the EV usage showing, the Monitor cable was a little short so extened it by 3m testing it on a kettle before and after the extension incase of any issues with monitoring over a longer distance, no issues with the 3.6m cable now

A1 works fantastic ,great app to use for control working well with ecoflow stream .

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.

Son una auténtica pasada, he comprado 4 y ahora mido el consumo de cada circuito del cuadro, la precisión es bastante buena e incluso se puede calibrar si alguno te mide algún watio en estático. La conexión con la app de shelly es muy sencilla y automáticamente, como todo lo de shelly, se detecta por home assistant por wifi en local, sin necesidad de conectarlo al cloud de shelly. Si se va la luz o se corta el wifi, reconectan enseguida sin mayor problema. Encajan bien en el rail y ocupan el equivalente a medio PIA o uno de los finos, por lo que para cuadros pequeños está bastante bien. En mi caso me permite detectar cuando estoy consumiendo por encima de lo esperado y apagar aires acondicionados, en el futuro teniendo placas solares te permite ver lo que produces y lo que consumes con facilidad. Lo que aún no he dado uso es a la función de relé que trae. No se me ocurre como usarlo en un cuadro de forma interesante. Añado capturas de la app de shelly y home assistant con las posibilidades que ofrece.
