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.
