Smarthing is using Z-wave wireless protocol, different country have different Z-wave frequency, US is 908.42 Mhz, where Malaysia approved z-wave frequency is 868.1 Mhz, (SKMM WTS SRD/EN 300 220). So you would hardly get z-wave product which is comply to Malaysia Standard.

I dont think samsung will launch this product in Malaysia in near future. As most of the "things" accessories by other manufacturers does not exist in Malaysia for their z-wave products.
