Using Home assistant's input_number in a "change node" to send data to "hourglass node"

[hansjeu]

I have a question about the "change node" module fron node red in Home Assistant.

Is it possible to call an input_number?

I use "change node" to send data to the "hourglass node."
I have an input_number where I enter the number of seconds it takes for the "hourglass node" to trigger an alarm.
I would like to use the input_number and send it to the "hourglass node" via "change node" as:
SET msg payload to the value PT5S.

Where the 5 is stored in the input_number.

Thanks in advance, Hansje
