5. 작동 모드
The DieseRC Smart WiFi Relay Module supports two primary operating modes: Inching (Momentary) and Self-Locking (Toggle). These modes can be configured within the eWelink app.
5.1 Inching Mode (Momentary)
In Inching mode, the relay will activate for a set duration (e.g., 0.5 to 3600 seconds) after being triggered, and then automatically deactivate. This is suitable for applications like garage door openers or pulse-triggered devices.
5.2 Self-Locking Mode (Toggle)
In Self-Locking mode, the relay acts like a standard on/off switch. One trigger activates the relay, and it remains active until another trigger deactivates it. This is suitable for controlling lights or other devices that require a continuous on/off state.

Image 5.1: This image illustrates the two operation modes: Inching mode, represented by a momentary push button, and Self-Locking mode, represented by a toggle switch.
5.3 블루투스 리모콘
The included Bluetooth remote control allows for local operation of the relay module. Each button on the remote can be paired to control specific channels or functions (e.g., ALL ON/ALL OFF).
5.4 APP Control (eWelink)
