Z wave
- 2. Definition Z-wave is a protocol used for wireless• Z-wave is a protocol used for wireless communication mainly in home-automation. This protocols caters needs of residential control and automation market which effectively and smartly control lighting, security systems.control lighting, security systems. • This protocol originally developed by Danish Startup Zen Sys and further acquired by sigma designs in 2008. The Z-Wave transceivers chips are supplied by sigma and Mitsumi. Output Power is 1mw or 0 dBM
- 3. Where it is Used • Home theatre, automated window curtain, swimming spa controls, home access and garage controls. Like many other Protocols i.e Zigbee and system aimed at theProtocols i.e Zigbee and system aimed at the office/home-automation market a z-wave automation system can be controlled via the internet with the Z-wave gateway or central control device serving as both the Z-wave hub controller and portal to the outside.
- 4. Network Setup Routing and Topology • Z-wave device connect via source routed mesh network architecture. A Z-Wave network can assist of upto 232 devices with the option of bridging network if more devices are required.bridging network if more devices are required. Z-wave based smart devices can communicate to one another by using central nodes (hubs) to actively route around.
- 5. • A message from node A to node C can be effectively transferred even though two nodes are not within range, providing that a third node B can communicate with nodes A and C.node B can communicate with nodes A and C.
- 6. That is the reason a Z-Wave network can span• That is the reason a Z-Wave network can span much further than the radio range of a single unit. Every device must be included to the Z- Wave network before it can be controlled via Z- Wave. We can add devices through pairing andWave. We can add devices through pairing and adding by pressing a sequence of buttons on the controller (Hubs) and on the device being added to the network. The sequence only needs to be performed once after which the device is always recognized by the controller (Hubs).
- 7. TOPOLOGY • Every Z-wave network is identified by a Network Id and• Every Z-wave network is identified by a Network Id and each smart device is further identified by a Node Id. The network Id (also called Home Id) is the common identification of all nodes belonging to one logical Z- Wave network. The network Id has a length of 4 bytes and is assigned to each device by the primaryand is assigned to each device by the primary controller and when the device is included into the network. Nodes with the different Network Ids cannot communicate with each other. The node id is the address of a single node in the network. The node id is the address of a single node in the network . The node Id has a length of 1 byte.
