Sonoff Mini-D

Description

Dry contact (Voltage-free contact) acts purely as a bridge for signal transmission between two points, typically in the form of an open or closed circuit that does not have a direct power supply. The power supplied to the module is completely isolated from the switched load, which helps prevent electrical faults and enhances safety.
