4-Channel Smart Wi-Fi Switch with RF Control
4-Channel Smart Wi-Fi Switch with RF Control
The Sonoff 4CH R3 is a 4-channel switch designed for DIN-rail mounting.
It supports the connection and control of 4 electrical devices, which can be turned on/off separately via the buttons or the EweLink app.
The housing is designed for DIN rail mounting! A standard metal rail widely used for mounting circuit breakers and industrial control equipment inside equipment racks.
These products are typically made of cold-rolled carbon steel sheet with a glossy galvanized or chrome-plated surface finish.
With the EweLink app, you can turn on/off from anywhere at any time, and you can set single/repeat/countdown schedules to turn on/off at a specific time and share them with others so they can control them together
The new improvement in the 4CHR3 and 4CHPROR3 compared to the 4CHPR2 and 4CHPROR2 is that users can set these 3 operating modes on the eWeLink app instead of on the hardware itself, making them easier to use. So you can enable the auto-lock mode to turn on/off 4 connected devices separately, the interlock mode to turn on 1 connected device at a time and turn off the rest of the devices simultaneously, and the inching mode to turn on 1 connected device and then have it automatically turn off after a set time (0.5–3600 seconds). For devices located far from the switch, you can create a mobile unit using a DIN rail to connect them. Simply activate the devices via voice command when the switch is paired with Alexa and Google Home.
