Z-Wave is the next-generation wireless standard for home automation. It lets you remotely control all your home electronics. The technology uses simple and low-powered signals that can easily travel through walls and floors. Z-Wave unites all your home electrical and electronic devices into one wireless network. The technology comes embedded in some devices, and it can also be added to almost any electronic device in your home, such as lighting, thermostats, HiFi, TV, and other household appliances.
Z-Wave technology enables devices to send or receive control commands. Z-Wave devices can work individually or in groups and are also capable of being programmed into events that trigger multiple devices either automatically or with remote control. Z-Wave comes with capability of confirming when the signal has reached the device and when it responds to the command.
Unlike Wi-Fi and other wireless technologies that are used primarily for high-bandwidth data transmission, the Z-Wave system operates at a sub-GHz frequency for low-level functional commands such as lights on or off, volume control, thermostat control, etc. Z-wave is interference tolerant, which means external wireless devices like cell phones, Wi-Fi routers, and cordless phones will not disturb the use a of Z-Wave enabled device.
It is also possible to control your Z-Wave devices remotely from an Internet connected PC and even through your cell phone, from anywhere in the world. controlthink is a vendor of Z-Wave PC software, a software developer kit, and a high-quality USB Z-Wave controller that allows you to monitor, control, and configure networks of Z-Wave devices from a PC.
