Tut was es soll
Gut. Einfach zu installieren. Aber ohne cloud-anbindung bringt es gar nichts. Vor allem, wenn man mit dem Gerät balkonkrafter steuern möchte

Shelly Pro 3EM + Switch + Contattore da 100A monofase
Ottimi prodotti facile installazione e configurazione lo usato nel mio impianto fotovoltaico controllando i tre carichi principali CASA, LABORATORIO, LUCI. Ora acquisterò quello con 2 pinze da 50A da inserire sugli ingressi dei due inverter in parallelo. Per ora sembra che funzioni tutto bene io li uso con Homeassistant speriamo che durino nel tempo per adesso sono molto contento e li consiglio a tutti
