S-mate: it is a three channel switch modification module, which is used to modify the ordinary switch in the home, turn it into an intelligent scene switch, and linkage control other intelligent devices1-2-3. Minir3 s-mate combination:Most intelligent products need zero fire power supply to work. In some families, there is only live wire and no zero wire in the switch box. Because the s-mate can be connected to an external switch, it does not need zero fire line power supply (battery power supply), and because the s-mate itself is not networked, it needs to communicate with other devices through devices with networking ability as a gateway. Therefore, the combination of mini R3 s-mate provides a solution to the intelligence transformation of single fire switch3..Please upgrade both the firmware and eWeLink APP to the latest version(4.18) before using this MINIR3 & S-MATE4..Have you ever encountered these similar situations when considering a simpler way to set up and control your smart home? Smart lighting off when the switch is off? No neutral wire in the assembly box? Now, S-MATE can help you solve this problem.5.MINI R3 is a small body with powerful functions, the maximum load current can become 16A that make it a powerful solution to repair your devices.
