Z Wave Device Node

This node works in conjuction with the main Z-Wave JS Controller node. It is used to send and/or receive messages to a single or multiple Z-Wave devices.

Setup

The Mode will determine which Z-Wave device(s) this node will communicate with. See below for more information.

The Network Mode will determine if the node will send, receive, or both.

Send mode will send messages from Node-RED to the Z-Wave device(s).

Receive mode means it will receive messages from the Z-Wave device(s) to your Node-RED flows.

Send/Receive will of course do both sending and receiving.

Mode Option Details

All Nodes

• Device node will Output messages for all Nodes
• Messages Input to the Device node will require a node property

Multiple Nodes

• Device node will Output messages from the specified Nodes
• Input messages will be sent as individual messages to each selected node
• If a node property is specified in the Input, it will only address that node but will continue sending Output payloads for all selected nodes

Multicast

• Like Multiple Nodes, but uses Z-Wave Multicast for Input messages
• The node property in your Input messages will be ignored
• Limited to Value API setValue and CCAPI set type commands
• Requires that the selected devices support Z-Wave Multicast methods

Specific Node

• Will listen for updates on the specified node only
• If Input is sent with node property, it will be ignored

As Specified

• Will listen for updates on the specified node, whichever node was specified most recently in an Input message
• Messages which are Input will need a node property specified

Subflow Variable

• Like Specific Node, but the Node ID is taken from the ZW_NODE_ID subflow Variable
• The node property in an Input message is ignored

Input Messages

It is highly recommended to form Input messages using the cmd-factory node.

The input to this node is expected to be a msg.payload object containing a Z-Wave command. The device node can receive commands for the configured device(s) Devices on your Z-Wave network, as determined by the Node ID(s) field.

The format of each msg.payload object is dependant on which API is being used. The device node will accept any command from either Value API or CC API. Follow the links for more details on the proper formatting and message options for each API.

Output Messages

Messages will be Output from this node according to the Mode chosen. See above for details on each mode option.

It is recommended to use the event-filter node immediately following the zwave-device node in order to filter and sort the messages coming from your device.
