2. Definition
Z-waveis a protocol used for wireless •Z-waveis a protocol used for wireless
communication mainly inhome-automation.This
protocols caters needs of residential control and
automation market which effectively and smartly
control lighting,security systems.control lighting,security systems.
•This protocoloriginallydeveloped by Danish
Startup Zen Sysand 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
andgarage controls.Like many other
Protocols i.eZigbeeand system aimed at the Protocols i.eZigbeeand system aimed at the
office/home-automation market a z-wave
automationsystem 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 upto232 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 and Wave. 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 primary and 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.

8. Z-Wave Plus

V2) is Z-Wave Plus Certified.
