The Sonoff 4Ch ProR3 is a remarkable 4 channel Wi-Fi and 433 MHz RF switch that is capable of managing 220V as well as 12V devices. The switch can be placed on its own or mounted on a DIN rail inside or outside of the distribution box.
This switch can be used to remotely switch a device or circuit (max. 10 A per channel) on or off via WiFi, RF remote control, scheduled timers or the on-device push-button switch. Voice control is also possible via Google Assistant or Amazon Alexa.
Wi-Fi connectivity enables users to remotely turn this switch on or off from anywhere in the world via the free app, e.g. switch on interior home lights before leaving the office or set a timer to switch exterior lights on at 8pm every night and off at 5am.
Supported switching modes include self-locking, interlocking and inching modes. Self-lock is the normal 1-press for on and a second press for off. Interlock is press 1 button for on and another for off. Inching allows you to let the switch turn on for a few seconds then goes off, similar to a pulse switch.
Users can also create 8 enabled single, repeat or countdown timers to automatically turn on/off at the specified time. Timers will run even when the network is unavailable.
Access to control switches can easily be shared via the Ewelink app.
- The RF Remote is not included and is available separately.
