Specifications

Setup

1. Wiring the Module:

The DieseRC Smart WiFi Switch features passive output (dry contacts) with Normally Open (NO), Common (COM), and Normally Closed (NC) terminals. It can be powered via a 5V USB input or a DC 7V-48V input.

Figure 3: Various wiring configurations for the smart switch. This includes connecting to a DC device, integrating with a standard switch, and controlling an electromagnetic lock. Power can be supplied via DC 5V/0.5A USB or DC 7V-48V.

Important: Ensure correct polarity when connecting DC power. The module's output terminals (NO, COM, NC) act as a switch for your connected device, providing a dry contact closure.

You can configure the operating mode within the eWelink application settings for the device.

2. eWelink APP Control:

Once paired, you can control your device from anywhere using the eWelink app.
