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.

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!

Works great! Just be sure the clamps face the right direction
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.
