Hello.
I’m using sensors for NCD products On NODE-RED, the alarm sounds when the temperature value of the sensor is higher than the set temperature value.
If the alarm goes off and the default color of the LED is green, if the temperature is higher than the set temperature, the alarm goes off together and you want to change the color of the LED to red.
Please help me
Hi,
It sounds like you are using one of our temperature sensors to monitor an asset and are using a Node-Red Dashboard widget LED to indicate pass or fail state of the temperature. Have you created a Node-Red flow yet? If so can you export that Node-Red flow and share it? If you do not have anything yet let me know and I can put together an example for you.

Thank you. I’ll post the chords
Can I get an example JSON file?
I don’t believe the msg.payload is being set correctly when being passed to the input of your template node. Here is a simple example that just changes the color of the LED widget. Maybe it will help you accomplish what you are trying to do.

Thank you.
Just one more thing. Can I ask you a favor?
In the case of LEDs, the warning light should be turned on when the motor temperature rises and vibrations are severe, so it doesn’t matter if you don’t distinguish colors, but I hope you can make or correct the wrong part by looking at Json.
You can add a second switch node to the output of the set temperature limit node which will check the vibration readings or you can simply add additional conditions to the set temperature Node which checks the vibration readings. Is this what you are asking?
