How to restrict a flow's output based on time of day

General
1

I am very new to Node-Red. I am using Homeseer automation for lighting control. Using Homeseer's documentation (and hours of experimentation) I was able to create a NR flow to have an outdoor motion sensor cause my Amazon Echo devices to announce "Motion detected" when the sensor is triggered.
However, I don't want this to happen during nighttime hours.
My question is, how do I add a node to my system that lets my flow determine the time of day, so I can use a switch node (?) to only allow the Echo trigger during specific hours of the day? I am using NR 4.0.9
TIA

You could use the time range switch node.

You could also use a switch node and a JSONata expresstion to output time and check if betweeen times in 24hr format
e.g.

[{"id":"14e67ff4e0591ac4","type":"inject","z":"d1395164b4eec73e","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":" {     \"relay\":0,     \"on\":true }","payloadType":"json","x":330,"y":2220,"wires":[["675924b00eaaa4da"]]},{"id":"675924b00eaaa4da","type":"switch","z":"d1395164b4eec73e","name":"","property":"$number($moment().format(\"Hmm\"))","propertyType":"jsonata","rules":[{"t":"btwn","v":"700","vt":"num","v2":"2200","v2t":"num"}],"checkall":"true","repair":false,"outputs":1,"x":490,"y":2220,"wires":[["4c147035c4b63827"]]},{"id":"4c147035c4b63827","type":"debug","z":"d1395164b4eec73e","name":"debug 2565","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":690,"y":2220,"wires":[]}]

Should only pass message if between 700 (7 am) and 2200 (10pm)

Sounds like just what I need. But, being a complete newbie to node-red, when the install instructions say to "change directory to your node-red installation", exactly which Windows directory would this be? I can see the NR installation created more than one.
I tried installing another node, and it did not appear in my node list, so perhaps I wasn't in the correct directory when I issued the command.
Thanks

In the right top hamburger menu, you can install nodes via manage palette

Got it. Thanks!
