If this product is out of stock, then you may order similar product from here.

SONOFF 4ChR3 & 4ChProR3 are both 4-gang Wi-Fi Smart Switches designed to give you the ability to integrate smart control into your existing home to enable a smart home. 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 that 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 RM433 remote controller.

Actually, SONOFF has released two types of 4-gang smart switches (4CHR2 and 4CHPROR2) that come with almost the same functions as 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 the eWeLink APP instead of the hardware itself, making it 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 the 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 movable space using a DIN rail to connect them. Simply activate devices through your voice when the switch works with Alexa and Google Home smart assistants.

4Ch Pro R3 is available at a low price in Karachi, Lahore, Islamabad, Gujranwala, Multan, Sialkot, Rawalpindi, Faisalabad, Gujrat, Peshawar, and other cities of Pakistan.
