Each smart switch has 4 gangs that can be used to control lights and other home appliances at the same time in four areas of your home. There is a major difference between 4CHR3 and 4CHPROR3, which is 4CHPROR3 is designed with an additional function for RF control. The function is purposely adopted to make you turn on\/off the device connected with 4CHPROR3 via the SONOFF RM433 remote controller.\u003cbr\u003e\u003cbr\u003eActually, SONOFF has ever released two types of 4-gang smart switch (4CHR2 and 4CHPROR2) which comes with almost same functions with 4CHR3 and 4CHPROR3. But all the above units are still different in 3 working modes including self-locking, interlock and inching mode. The new improvement on 4CHR3 and 4CHPROR3 compared with 4CHPR2 and 4CHPROR2 is for users to set these 3 working modes on eWeLink APP instead of the hardware itself, easier to operate. So you can enable self-locking mode to turn on\/off 4 connected devices separately, interlock mode to turn on 1 connected device every time and turn off the rest of devices simultaneously and inching mode to turn on 1 connected device and then make it turn off automatically after a given time (0.5 - 3600s). For the device away from the switch, you can create a moveable space in virtue of a DIN rail to make them be connected. Simply activate devices through your voice when the switch works with Alexa and Google Home smart assistant.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv class=\"detailmodule_image\"\u003e\u003cimg style=\"margin-bottom:10px\" class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/S1734959e0ece4f039c7643d9500b6c4dQ.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-title\"\u003eQuick to Access 3 Working Modes\u003c\/p\u003e\n\u003cp style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-content\"\u003eCompared with 4CHPROR2, you can access self-locking interlock and inching mode on APP directly.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cimg style=\"margin-bottom:10px\" class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/S0d5c5161aeb945cc8b1728c22fa32956z.jpg\" slate-data-type=\"image\"\u003e\u003cimg style=\"margin-bottom:10px\" class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/Safcbdfdb73dd46498634f7dbc0c0e7b98.jpg\" slate-data-type=\"image\"\u003e\u003cimg style=\"margin-bottom:10px\" class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/S5e4b6d54d5b449c9b09e4c7f29fdfd40g.jpg\" slate-data-type=\"image\"\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-title\"\u003eRun 4 Devices Separately- Self-locking Mode\u003c\/p\u003e\n\u003cp style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-content\"\u003eAllow you to turn on or off 4 connected lights independently.\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg style=\"margin-bottom:10px\" class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/S5358ee7f2f954cb1a5a760241192dabfd.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-title\"\u003eAutomate More Devices- Interlock Mode\u003c\/p\u003e\n\u003cp style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-content\"\u003eOne channel controls one work status, enable interlock to turn on 1 channel and turn off other channels simultaneously.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cimg style=\"margin-bottom:10px\" class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/S350ddc1037cd46b8bd8a05c41eba4744Z.jpg\" slate-data-type=\"image\"\u003e\u003cimg style=\"margin-bottom:10px\" class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/S46e7ad99f22749f697ade5c03531f8d85.jpg\" slate-data-type=\"image\"\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-title\"\u003eKeeps On for A While, Then Turns Off Automatically- Inching Mode\u003c\/p\u003e\n\u003cp style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-content\"\u003eDon't want to stiffly fumble in the dark for the way?
