Description

The Sonoff BASIC R3 is a compact, Wi-Fi-enabled smart switch designed to bring intelligence to standard home appliances and lighting. It operates on standard AC power (100-240V) and integrates directly into your electrical wiring to provide remote control via smartphone, voice commands, or automated schedules. Its core functionality is managed through the eWeLink ecosystem, offering a user-friendly interface for real-time status monitoring and scene creation.

Beyond standard cloud control, the R3 version includes a crucial DIY mode, allowing advanced users to flash custom firmware such as Tasmota or ESPHome. This opens the device to local network (LAN) control via a built-in web server and REST API, making it independent of cloud services and ideal for privacy-focused or complex home automation setups. The switch is built with a robust ABS housing and is rated for high-current applications, making it a reliable component for smart home retrofits.

Frequently Asked Questions

How do I flash custom firmware like Tasmota onto the Sonoff BASIC R3?

To flash Tasmota, you need to access the device's serial pins. Open the case and connect TX, RX, GND, and 3.3V to a USB-to-serial adapter. Hold the button while powering on to enter flash mode. Use Tasmota's web flasher or esptool.py to upload the firmware. After flashing, configure Wi-Fi and MQTT settings via the new web interface for local control.

What is the maximum load the Sonoff BASIC R3 can handle?

The Sonoff BASIC R3 is rated for a maximum resistive load of 10 Amps at 100-240V AC, equating to 2200 Watts. This is suitable for controlling most household lighting, fans, space heaters, and small appliances. Do not exceed this rating, and ensure your wiring and the connected device are compatible with the switch's specifications.

Can I control the Sonoff BASIC R3 without an internet connection?

Yes, with its DIY mode and custom firmware like Tasmota, you can enable full local network (LAN) control. The device hosts a web server accessible via its local IP address. You can also integrate it with home automation hubs like Home Assistant using MQTT or the REST API, allowing operation entirely within your local network without cloud dependency.
