Switch node to control ui

[budiman098]

hy guys, can someone help me?
i have a problem with my switch node in my node-red, the example i want make some node to read value number 12 and another node read value 15 (i inject the value), and the system in dashboard.

but i want make the system to read the value when i push the one switch button. so the idea is when i push the button, the system will on and start read the value.

i hope you can help me, thanks.

regards,

Hi, while I'd like to help you, after reading what you wrote I'm confused are you takling about the switch node, the ui-switch node or both? Fully naming the node makes it easier for someone else to understand.

Please provide your flow (see: How to share code or flow json which will help me to understand your need.
