SONOFF Wi-Fi Smart Switch MINIR4
Home automation starter Works via Wi-Fi without a hub Control via app or button
A simple module for anyone who wants to quickly upgrade a traditional switch to a smart solution and control lights or other devices locally or remotely.
- Suitable for installation in existing switches without major interventions.
- It offers the option of controlling devices via phone or manually on the switch.
- It allows you to remotely turn lights on or off, even when you are not at home.
- Suitable as a first step into a smart home with gradual expansion of options.
- Small size: its compact size allows it to be installed in various mounting cabinets, including the smallest European standard.
- External Switch Control: Easy connection to momentary switch, door exit switch, SPDT switch, latching switch and even dry contact sensors.
- Relay disconnect mode: MINIR4 has a “relay disconnect” mode, which means that the states of the external switches and the relay are separate, so operating the external switch button will not affect the state of the relay.
- eWeLink-Remote Control: MINIR4 is a smart switch with “eWeLink-Remote” gateway function. You can add “eWeLink-Remote” sub-devices, R5 and S-MATE, after pairing with MINIR4, both R5 and S-MATE can act as remote controllers to locally control MINIR4 via eWeLink-Remote signal.
- Safe and reliable: TÜV, CE and FCC certifications ensure a safer and more reliable product.
Mini as ever
A brand new product that turns traditional switches into smart switches, automating lights and electronic devices. It is 40% smaller than MINIR2, fits into various mounting boxes, including the smallest European standards.
Extremely fast ESP32 chip
The ESP32 chip is a highly sought-after solution for smart home products, boasting exceptional security and reliability. With fast dual-core performance and ample memory, you can trust its ability to provide long-lasting, stable performance.
Transform your switches with seamless compatibility
Easy connection to momentary switch, door exit switch, SPDT switch, latch switch and even dry contact sensors.
Disconnect the relay
“Disconnect Relay” means that the states of external switches and relay are separated, so operating the external switch button will not affect the relay state. As below, the smart light will not be offline after enabling “Disconnect Relay”, and the app can control the smart lights.
Additional protection
Power-on delay status
If power is restored after a power outage, set some devices to delay the execution of the power-on state. Avoid turning on all devices at the same time, which will cause high currents to damage the devices and create a potential safety hazard.
