3. Installation and Setup
3.1 Wiring Instructions
The SONOFF MINI R2 supports various wiring configurations, including connection with external switches like SPDT switches and NC/NO push-button switches. It is recommended to install the front side of the MINIR2 outside of metal junction boxes to ensure optimal Wi-Fi signal.
The device can be integrated with existing wall switches to maintain manual control alongside smart functionality.
3.2 Advanced Wiring Modes
The MINIR2 supports different modes for advanced control:
- Edge Mode: Both rising and falling edges can trigger the relay state change. This mode is ideal for connecting a SPDT switch to achieve two-way control of a device.
- Pulse Mode: Falling edge triggers the relay to reverse in level jumping. This mode is ideal for push-button switches that are triggered once after being pressed and automatically bounce back.
- Following Mode: This mode allows the light to follow the ON/OFF direction of the wall switch, even if the physical switch state does not correspond to the light's state. It can also connect dry contact sensors.
