Sorry, there was a problem. Please try again later.The Smartthings Hub supports a large number of devices by using both Zigbee and Z-wave protocols. Z-Wave support 232 devices minus 1 for the hub itself, and Zigbee doesn't list a number, but is likely hundreds too. Z-Wave Plus is the latest protocol and since it uses 908.42 MHz it is not likely to interfere with WiFi services, whereas Zigbee uses the same 2.4 MHz as most WiFi. The device is the defacto for home automation because of it's compatibility with so many devices. Also Samsung provides an API with developer interface so the compatibility list is sure to grow. I highly recommend this device.
