Sonoff 4CH & 4CH R2 are 4-gang switches with din rail mounting. Sonoff 4CH (R2) 4 gang light switch supports to connect and control 4 electrical appliances, which can be turned on/off separately by the buttons or iOS/Android App EweLink. Besides, with the multi gang switch, you can check real-time devices status for each device on App. Owning a Sonoff 4CH (R2) multi gang switch means you have 4 Sonoff basic WiFi switches integrate together. 

The enclosure is din rail mount supported! 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 (R2) 4 gang WiFi light switch 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 (R2) is hacker-friendly that you can flash your firmware without difficulty. Read ESP8285 datasheet.

Works With Amazon Alexa

You can ask Alexa to turn on/off Sonoff 4CH (R2).

Standard voice control commands phrases (if you just say the device name, Alexa will turn on/off all the 4 gangs immediately):

Alexa, turn on {deviceName}
Alexa, turn off {deviceName}

Alexa, turn on {deviceName} {gangName}
Alexa, turn off {deviceName} {gangName}

The default names for the 4 gangs are: outlet 1, outlet 2, outlet 3, outlet 4. You can change the name if you like.

Explanation: if the device name of your Sonoff 4CH (R2) is "My Switch", the gang name is "Outlet 1", then you can control with "Alexa, turn on My Switch Outlet 1".
