A simple routing node that will latch the output and route all subsequent messages to that output.
E.g. Drag the node into your workspace and configure it to have 3 outputs. Send a string payload of latchOutput 3
to the node. This will cause the node to route all subsequent messages to output 3.
Outputs are not zero indexed. So latchOutput 1 will route subsequent messages to the 1st output.
Messages which alter the latch are consumed and do not get sent via an output.
Change directory to your node red installation:
$ npm install node-red-contrib-latching-router
There isn't much to configure. Choose the number of outputs you need. The minimum is 2 as it makes no sense to only have 1 output for this node.
