Hi, i am completely new in node red.
i need a help to create a flow which can output "cool" and "off" based on the value between range of 33 and 29 respectively but i should also be able to change the range from node red dashboard using ui_numeric node.
kindly help.
thanks
For the range you could use a switch node:
Maybe start with fixed values first and once this is working add the dashboard components / features.
What have you tried so far?
Edit: Reading my answer above is maybe not what you are trying to do. But I think the switch node can help to solve your problem.
so far i have figured out to output desired payload based on the reading received from temperature sensor, but i cant figure out how to change value range usingui_numeric node from nodered dashboard.

As a start you can try something like this:
