Sonoff 4CH – a reliable and compact controller for anyone who wants to control several devices at once. The relay lets you turn on, turn off and configure four independent power channels through the eWeLink app. It is ideal for lighting in multi-zone spaces, ventilation systems, or even several household appliances from a single smartphone. Thanks to DIN rail mounting, the relay fits neatly into your distribution panel, keeping the whole home infrastructure tidy and easy to manage.
Why choose Sonoff 4CH:
4 independent channels: Control four appliances or lighting lines separately – switch them on individually or all at once with a shared scene.
Remote control: Control your home from anywhere in the world via the eWeLink app.
Flexible scenarios: Set up schedules, countdown timers or smart scenes linked to other devices in the Sonoff ecosystem.
Voice control: Full compatibility with Amazon Alexa, Google Assistant and Alisa lets you control the lights without a smartphone.
Professional installation: The housing is designed for a standard DIN rail, ensuring safe and convenient installation in an electrical panel.
