Timer to start something after x seconds

[mihail4anov (Michael)]

Hi.
I want to set timer from HA Lovelace to turn off my TV after X seconds.
I have created inputnumber in Lovelace (which responds for seconds) and created a following flow. But Wait Untill node does not work as I expect. It continues to wait and does not fire.

Hi, i am using the following to do what you want. But it uses a different logic:

Set up a variable timer in node red

Of course thats possible. As always, in node red there are probably a million and one ways of doing this. However, what I did was to create an input number slider helper and when it reaches 1 i trigger a 1min timer within nodered that then fires my switch. In a seperate flow, I am taking the value of the helper and after a minute i will set it to -1 of its previous value. With that, I always have a visual representation of how much time is still available on the timer, and you can always just…

[mihail4anov (Michael)]

Thank you. But it is not exactly what I want.
Can you share your logic?

The Node and Screenshots are linked in the post. Just click on it to see more.

Why not use the helper “timer”.
It’s really great and counts down to time up in the state.

I use those as our timers and all you need to do is activate the timer and delay 2 seconds just to be sure the state changes.
Then wait until state is idle.

[Hellis81]

Here is my timer using node red, timer helper and IFTTT to capture the minutes I want the timer set on.

With this settings in IFTTT:

So, I say “Hey google. 5 minutes” and it calls IFTTT and IFTTT does a http request that creates an event in HA/node red uses to set a timer of the said minutes and then speaks a message when the time is up.

[mihail4anov (Michael)]

Ok, I think I need to describe the whole idea.
I want my MiBand to track my sleeping state (it is done). And to turn off my TV when I fall asleep. (But mibamd is not very accurate and that is why I want to add timer. As sometimes MiBand thinks that I am already sleeeping too early). I also want to be able to stop timer if MiBand changes my sleeeping state. For exaple when I go to bathroom before I really fall asleep.

I have never worked in NR with time before. And I have no idea how to realise that.

[mihail4anov (Michael)]

I have found the answer.

node-red-contrib-countdown-2

[AlmostSerious (Marcus Peters)]

Indeed, that is a bit of a different use case than all of us had in mind

In that case you can basically use any countdown, or timer node within NodeRed.
Just make sure to cancel it once your MiBand detects not_sleeping again.

I use a subflow that uses the same logic with a 10sec timer for my motion detectors:

[FutureTense]

I solved this by using the “wait until” node. I just picked a random entity like sun.sun and set the timeout to 5 seconds.
