11-key handy remote control, operated with CR2025 cell battery. Signal passing through walls, no need to point at the receiver. Smooth Dimming: Brightness adjustable, flashing (speed adjustable). 8 dynamic effects, 10 levels of dimming, 256-Grade PWM. Can be switched from 1-to-1 paired or 1-to-multi paired easily. ATTENTION: To achieve 1 to multiple control, must purchase multiple sets of LED controllers. There is some chance that the RF remote controller will be interrupted by another RF remote controller, or by other electronic equipment which are also working at the same frequency. In this case, try to set the remote and the receiver to be working at 1-to-1 mode may help to tackle this issue. How to do 1-to-1 and 1-to-multiple pairing: 1) When you need to do 1-to-1 match with a remote and a receiver, first make sure only 1 receiver is connected to the power, the other receivers can not be working. Press the 'SPEED +' & 'SPEED -' buttons of the remote control at the same time. 2) When you need to do 1-to-multi match with a remote and a number of receivers, first make sure all the receivers are connected to the power and working. Press the Green button (also regarded as the 'LIGHT' button), all the receivers will be set default again which is 1 to multiple working mode (synchronously).

Overview: Sonoff 4CH Pro is a 4 gang WiFi switch. It supports switch among 3 working modes: interlock/self-locking/inching(0.25-4s adjustable) mode. It integrates with a 433MHz RF receiver module, making the switch can 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 network is unavailable. To let the devices be controlled by their family, they can simply share the devices to them and give specified timers permissions. They can even create some scenes or smart scenes to trigger ON/OFF the switch. In self-locking mode, users can turn on/off the 4 connected devices instantly and separately. In interlock mode, users can turn on 1 device every time, and turn off other devices at the same time. In inching mode, users can turn on connected devices for 0.25-4s(the time is adjustable). Users can set some devices in inching mode, while the others in interlock mode.
