If the service is not running, try starting it manually via sudo systemctl start apache2. If you run into issues, it is possible that there is another service already using the default port 80. Stop the other service and start apache2. User tips: If the device has been paired with eWeLink APP, reset the device is necessary by long pressing the pairing button for 5 seconds to enter Bluetooth Pairing Mode.

You need to access the serial interface. The four serial pins (3V3, Rx, Tx, GND) are available in the middle of the PCB, right next to the on-board button. Newer versions of the Sonoff Basic device provide five pins below the button, ignore the pin furthest away from the Button (GPIO14 or I02) if available. The square pin right next to the button is the 3.3V line. When the “device type” of the device service does not match with the “device type” of your application or client, or the device API interface version of the device service is higher than your application or client’s, the application or client should not parse out the “device information” and call the device API interface, but prompt the specific reason for users why the device cannot be controlled via LAN and suggest to upgrade the application or client. For flashing the Sonoff Basic, hold the button while connecting the 3.3V power. The LED remains off until the flashing process is done and the board is rebooted.

Without changing its original smart features, BASICR2 made the upgrade and optimization mainly on its safety to provide the higher value and usage experience to our users.

When Sonoff R3 is powered on while the jumper is installed, it will try to connect to the following WiFi credentials: SSID: sonoffDiy

Note: SONOFF BASICR3 does NOT have 433Mhz RF receiver module. If you want a diy smart switch with RF function, please buy SONOFF RFR3.

Fast double blinking – The device connects to the WiFi successfully and is able to be discovered through mDNS and respond the request from LAN network. Fortunately, there are alternatives that require flashing a different firmware onto Sonoff devices. The Tasmota firmware, for example, is a well-known alternative that provides easy integration with existing home-automation servers and let users control devices via multiple methods, such as webUI, HTTP requests, and MQTT, all of which can be accessed either locally or remotely or both. On top of that, it is free and open-source. Traditionally, flashing a Tasmota firmware onto a Sonoff device involves finding a serial connection, soldering a few cables/pins, and connecting the device to a serial-to-USB adapter. However, more often than not, this takes time, knowledge about electronics, and soldering very small components.
