Compact at 88 × 39 × 24 mm, the SONOFF BASICR4 Wi-Fi smart relay module installs behind an existing switch, under a ceiling light, or in a junction box to intelligently connect any load up to 10A without replacing existing electrical wiring.\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003e \u003c\/p\u003e\n\u003ch2 style=\"text-align: justify;\"\u003eMagic Switch Mode, eWeLink-Remote Gateway, and Bidirectional Local Control\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe major innovation of this model lies in its \u003cb data-index-in-node=\"50\" data-path-to-node=\"22\"\u003eMagic Switch Mode\u003c\/b\u003e: after a slight wiring modification to your mechanical switch, the relay remains permanently powered.

The power-on state memory configures the behavior of the SONOFF BASICR4 Wi-Fi smart relay module after a power outage: return to on, off, or the last recorded state, with a configurable recovery delay from 0.5 seconds to 59 minutes 59 seconds. The loop timer function automates recurring on\/off cycles at custom intervals.\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003e \u003c\/p\u003e\n\u003ch2 style=\"text-align: justify;\"\u003eSmart Scenes, Group Control, and Multi-platform Compatibility\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eGroup control allows multiple BASICR4 devices to be synchronized from the eWeLink app with a single gesture, ideal for simultaneously turning off all lights in a home.
