Input_number with node-red and condition

I have this card in Home Assistant and also have an automation in node-red to trigger the humidifier when the humidity is > 65 but I want to use the input_number slider in node-red but this doesn’t works.

I’m using the global variable to check the condition.
I’ve tried with:


but no success.

Any idea?

Thanks, It´s already solved. The problem was that the input_number was a string I just convert the string to number and problem solved

Hi jandrop
This is a really simple question, but I’ve wasted hours on it. How did you convert the string to a number? I’ve experimented and keep getting error messages whenever i try and use a pipe operator.

Post it as a new question and add some more details so that we can help you.


You can multiply by 1.
