The simplest way to make any appliance smart. The SONOFF Basic R4 (BASICR4) is a WiFi smart relay powered by the ESP32 chip — faster and more stable than previous generations. Wire it inline with any appliance up to 10A / 2,200W at 220V. Control via the eWeLink app, voice commands, schedules, and smart scenes. Features Magic Switch Mode for compatibility with wall switches, overheat protection, and eWeLink-Remote gateway support for the S-Mate2 and R5 controllers. No hub required — connects directly to your WiFi. MPN: BASICR4.

⚡ Key Features

  • ESP32 Chip — faster, more stable WiFi performance than older ESP8266-based models; smoother app response and more reliable connectivity
  • 10A / 2,200W at 220V — control lights, pumps, heaters, fans, irrigation solenoids, and most household appliances
  • No Hub Required — connects directly to your 2.4 GHz WiFi network; pair via the eWeLink app in seconds
  • Magic Switch Mode — keeps the Basic R4 controllable via the app even when the wall switch is turned off; compatible with most double-pole rocker switches and 3W–100W LED/CFL/incandescent loads
  • eWeLink-Remote Gateway — pair with S-Mate2 or R5 Scene Controller for two-way local control without WiFi — the Basic R4 acts as the gateway
  • Built-In Overheat Protection — temperature sensor monitors heat levels and cuts power if overheating is detected; protects your appliances and wiring
  • Schedules & Timers — countdown, daily schedules, and loop timers for automated routines; "Turn on garden lights at sunset, off at 11 PM"
  • Inching / Pulse Mode — momentary relay pulse for gate triggers, garage doors, or irrigation solenoids
  • Power-On State — choose On, Off, or Last State after power returns (load shedding recovery)
  • Voice Control — Amazon Alexa, Google Assistant, SmartThings, and Siri Shortcuts
  • Home Assistant — supported via eWeLink add-on, SonoffLAN (HACS), or Tasmota/ESPHome (ESP32 flash)
  • Group Control — control multiple BASICR4 switches simultaneously from the eWeLink app

🏠 Perfect For

💡

Lights & Ceiling Fans

Wire inline to control any light or ceiling fan from your phone. Set schedules, voice commands, or use Magic Switch Mode so the wall switch doesn't disable smart control.

🌿

Garden & Irrigation

Control irrigation solenoids, pond pumps, or garden lights on a schedule. Use inching mode for momentary valve triggers. Automate watering without expensive irrigation controllers.

🔥

Geyser Timer (Up to 10A)

For geysers drawing under 10A (~2kW element), the Basic R4 can serve as a simple on/off timer. Schedule heating before you wake up and after you get home. Track costs with scenes.

🏗️

DIY & Maker Projects

The Basic R4 is the Swiss army knife of smart home DIY. Control any AC-powered device, trigger relays, automate pumps, and integrate with Home Assistant via Tasmota or ESPHome.

💡 Magic Switch Mode: Normally, turning off a wall switch cuts power to the Basic R4. Magic Switch Mode detects the switch position change and keeps the relay responsive — so you can still control the light via the app even if someone flips the wall switch. Works with double-pole rocker switches and loads between 3W–100W.

❓ Frequently Asked Questions

Does it need a hub?
No. The Basic R4 connects directly to your 2.4 GHz WiFi network. Just download the eWeLink app, scan the QR code, and pair. No Zigbee hub or bridge needed.
What's Magic Switch Mode?
Normally, flipping a wall switch off cuts power to the Basic R4 completely. Magic Switch Mode lets the Basic R4 detect the switch position change and stay responsive. You can still control the light via the app even though the physical switch is "off." Works with double-pole rocker switches and 3W–100W loads.
Can I use it for my geyser?
If your geyser element draws under 10A (approximately a 2kW element), yes. Most standard SA geysers have 2kW elements (~9A at 220V). For higher loads, use the POW Elite 20A or POWCT (100A CT clamp).
What's the difference between this and the MINIR4?
The BASICR4 is a standalone module with screw terminals and a larger enclosure — ideal for wiring into junction boxes, DB boards, or inline with appliance cables. The MINIR4 is designed to fit behind a wall switch. Both have the same 10A rating and ESP32 chip. Choose the BASICR4 for general-purpose inline switching; MINIR4 for behind-switch installations.
Can I flash Tasmota?
Yes. The Basic R4 uses an ESP32 chip. Flash via USB-to-serial for full local control with Tasmota or ESPHome, integrating directly with Home Assistant without cloud dependency.
Does it work during load shedding?
During load shedding, there's no power so the switch is off. When power returns, it restores to your chosen power-on state (On, Off, or Last State). Set "Off" for safety or "Last State" to resume normal operation automatically.
