                        Overview:
                         
                        Sonoff 4CH Pro R2 is 4 gang WiFi switches. They support switching among 3 working modes: interlock/self-locking/inching mode. 4CH Pro R2 supports to set 1-16s. (4CH Pro just supports to set 0.25-4s). This feature allows you to let your switch turn on for a few seconds then goes off, which works like a pulse switch. They integrate with a 433MHz RF receiver module, making them possible to be controlled by RF Remote. The Sonoff 4CH Pro smart switch is DIN Rail mounted.
                        Users can remotely turn on/off the connected lights/appliances by iOS/Android App eWeLink or 433MHz RF Remote. They can create 8 enabled single/repeat/countdown timers to automatically turn on/off at the specified time. The timers can run themselves even when the network is unavailable. To let the devices be controlled by their family, users can simply share the devices with their accounts and allow specified timers permissions. They can even create some scenes or smart scenes to trigger ON/OFF the switch.
                         
                        Works With Amazon Alexa:
                         
                        You can ask Alexa to turn on/off Sonoff 4CH Pro (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 is "My Switch", the gang name is "Outlet 1", then you can control with "Alexa, turn on My Switch Outlet 1".
