Sonoff 4CHPROR3 433Mhz RF Smart Switch Interlock Self Locking Inching Working Modes remote control via eWeLink APP Alexa<\/p>\n

SONOFF 4CHR3 and 4CHPROR3 are both 4-speed DIY WiFi smart switches that give you the ability to integrate intelligent control into your existing home and thus enable a smart home. Each smart switch has 4 groups that allow you to control lights and other household appliances in four areas of your home at the same time. There is an essential difference between 4CHR3 and 4CHPROR3: 4CHPROR3 is equipped with an additional function for RF control. The function was intentionally performed so that you can switch the device connected to 4CHPROR3 on and off via the SONOFF RM433 remote control.<\/p>\n

In fact, SONOFF has already launched two types of 4x smart switches (4CHR2 and 4CHPROR2), which have almost the same functions as the 4CHR3 and 4CHPROR3. But all of the above units still differ in three working modes, including self-locking, Locking and typing mode. The new improvement of the models 4CHR3 and 4CHPROR3 over the models 4CHPR2 and 4CHPROR2 is that users can set these 3 modes of operation in the eWeLink app instead of the hardware themselves, which facilitates operation. So you can activate the self-lock mode to turn on\/off four connected devices separately, the lock mode, To turn on a connected device each time and turn off the remaining devices at the same time, and the typing mode, to turn on a connected device and then turn it on after a certain time automatically turn off (0.5 – 3600s). For the device located away from the switch, you can create a movable space through a DIN rail, To connect it. Simply activate devices by voice if the switch works with Alexa and Google Home’s Smart Assistant.<\/p>\n<\/div>\n
