Most Sonoff devices use Quick Pairing Mode. Download the eWeLink app, power on the device, wait for the Wi-Fi LED to blink in a cycle of two short and one long flash, and tap '+' in the app to pair.
Sonoff devices primarily pair with the official eWeLink app for iOS and Android. Once set up, they can be integrated with Google Assistant, Amazon Alexa, and IFTTT.
Check the Wi-Fi LED status. If it flashes quickly once every two seconds, double-check your Wi-Fi password, ensure you are connected to a 2.4GHz network (5GHz is not supported), and verify your router's MAC filtering is disabled.
To restore a Sonoff device to its factory settings, you can either delete the device from your eWeLink app or press and hold the physical pairing button on the device for about 5 seconds until the LED flashes rapidly.
