Brilliant!
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!

CT leads are very short
A nice device. A level of electrical competency required for its installation. CT leads too short for my needs, had to install it in a secondary location. Noting that if I was installing it in one domestic DB the short CT leads would have been ideal to solve cable management. I'm not using the Shelley app to manage it, but my solar system picked it up really simply. I only see the data in half-hour chunks and if it misses a recording it doesn't heal but that might be my app rather than the device. I think the device stores all of its records for a number of months. Slightly expensive for one load but if you want the two channels and the switching probably good value.

FANTASTIC
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

Easy set up, but does not react to other equipment like the 3EM version.
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

Great device
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

Perfect for Home Assistant
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.

Buena compra
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.

Simple with many options
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.

Monitoraggio preciso e in tempo reale La precisione nel monitoraggio è uno dei punti di forza. Posso tenere sotto controllo i consumi in tempo reale tramite l’app Shelly o la mia piattaforma domotica integrata con Homey Pro, ricevendo dati dettagliati e facilmente leggibili.
