Review: 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. Review: Brilliant! - A fantastic bit of kit.
