Hello,
I’m quit new over here and busy migrating from a Homey.
I did get the basic started and did write some que’s (much more efficient then Homey 
)
Now I try to figure out when a door is open for 5 minutes say “door open” at TTS
When within the 5 minutes the door is closed the timer stops and reset until next time opening.
I do have TTS already up and running.
So I’m only looking for the smart timer part.
Any Idea how to make in node-RED?
From the top of my head, I think you’ll need to use something like global state variable to the time the door was open.
Have an inject node that is running every say 1min, effectively subtracting (using a function node) current time from the global state variable you set earlier and trigger the service when that reaches 5.
I’ve done similar, the key node in my attempt is a ‘wait until’. The 1st one (called initial timer) is triggered when the door is unlocked, and waits for 5 minutes, unless the door is locked again.
Then it sends a notification, and goes to a second timer which waits for 15 minutes before repeating the notification.

Thanks for thinking with me.
To be honest I do not understand how to programm the first two flows 
So I tried the 3th one.
That is working.
The only minus is that timer keeps running when door is closed after an open situation.
Is a timer using a lot off CPU time? Because I like to check a lot of doors 
You only need two nodes in reality, the event: states node and a trigger node. When the door closes (i.e, the sensor reports “off”), then the trigger timer is reset. Otherwise, it’ll send the message after 5 minutes.
That shouldn’t really matter unless you are in a VERY constrained environment. I have ~50-75 different timers running throughout my flows and it’s barely touching my CPU (running NodeRed standalone on a rPi4).
Wow thats the one.
Very nice to see all these options for the same questions.
I will ask another question in a new topic
Thanks
Thanks, good to know.
I also run on a RPI 4B, 4Gb.
So that must be strong enough
PS: Where to find this screen?
In my house, the first message may get ignored. Hence the repeat loop, but other than that it’s 3 nodes. Wait until does a similar job to trigger.
Both options avoid the need to add additional nodes, I like to minimise what I install as each one is a potential source of bugs and vulnerability
