What are the differences between INSTEON and ZigBee wireless technologies?
INSTEON is used by SmartHome for lighting products only. Other manufacturers are incorporating INSTEON in a variety of products. By contrast Control4 has a complete line of products for whole-house automation solutions that all use ZigBee. INSTEON uses the 900 MHz range where ZigBee uses the 2.4 GHz range. INSTEON also transmits dual signals over the air and the home power lines. INSTEON can support a practical unlimited number of devices in the home (16,777,216 to be exact) whereas ZigBee supports 256 devices per controller. INSTEON supports X10 addresses, ZigBee does not. Both of these wireless technologies as implemented by SmartHome and Control4 support mesh networks that get stronger with each device added. All devices in both networks repeat each received command, and neither wireless network requires a router in the configuration.
