Independent 4-channel design lets you remotely turn four home appliances on or off independently. Three versatile working modes: - Self-locking: control each connected device separately and maintain its state. - Interlock: turning on one device automatically turns off the other three. - Inching: devices turn on and then automatically switch off after a delay of 1 to 16 seconds. Two remote control options: - Control via WiFi with a smartphone app. - Control via 433MHz RF remote. Eight time schedules for automatic control: - Create eight enabled timers with single, repeat, or countdown modes to automatically switch devices on/off at set times. - Timers run locally and operate even when the network is unavailable. Use scenarios: - Set up daily lighting and appliance schedules to fit your routine while keeping independent control over each device. - Use interlock to prevent simultaneous operation and reduce energy use or avoid circuit overload. - Use inching to energize a device for a short duration for testing, brief pulses, or momentary actions.
