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 Wi-Fi switches integrate together.
The enclosure is din rail mount supported! 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 (R2) 4 gang Wi-Fi 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. Featured By RoboticsBD.
