Variable countdown timer

General
1

Hello,
I'm new to node-red, which I use with the Rhasspy voice assistant.
I'm trying to create a countdown whose duration is variable depending on the choice made vocally.
I manage to retrieve this value from the Rhasspy sentence, but can't figure out how to use it afterwards.

None of the nodes I've tried allow you to assign a variable to the countdown, all of them offer only fixed values (node-red-contrib-mytimeout and node-red-contrib-countdown-2).
Am I missing the right node or do I need to do something different?

I'd appreciate a clue,
Thanks

The trigger node will accept msg.delay in milliseconds to set a delay before passing on the second message. so set first output to nothing and check enable override with msg.delay. You can even set a unique topic and have multiple delays.

Thanks for your reply
Using the delay module, I managed to cobble something together.
It's probably not the best, but it works pretty well :

Not to put too fine a point but the mytimeout node will accept a timeout in the msg
msg = {
payload: 'on',
timeout: 60,
warning: 0,
topic: 'timer',
}

this set the time in the node, you can set it to any value you want and also several other parameters. They are listed in the node readme.
