Sonoff 4CH

Overview

Sonoff 4CH is an ESP8285 WiFi module based 4 channel (4-way) WiFi wireless switch. Sonoff 4CH supports to connect and control 4 home appliances, which can be turned on/off separately by the buttons or iOS and Android APP EweLink.Owning a Sonoff 4CH means you have 4 Sonoff basic WiFi switches integrate together.

The enclosure supports din-rail mount! A DIN rail is a metal rail of a standard type widely used for mounting circuit breakers and industrial control equipment inside equipment racks. These products are typically made from cold rolled carbon steel sheet with a zinc-plated or chromated bright surface finish.

Sonoff 4CH belongs to Sonoff family, definitely, it bears all the functions basic Sonoff has. In EweLink, you can remote turn on/off from anywhere at any time, set single/repeat/countdown timing schedules to turn on/off at a specified time, share to others so that they can control together.

Sonoff 4CH is hacker-friendly! You can flash external firmware!
