A flow can be started again before it is completed?

Flows
1

I think I understood, that a flow can not be re-started before it is completed.
To see if my understanding is correct, I thought I verify this with a simple flow (picture 1), that starts with
1* when I push a button
2* send a notification “aan” to my time line
3* wait 10 sec.
4* send a notification “flow beëindigd” to my time line

I thought - that pushing the button again before 4* is completed, would be ignored.
My time line tells me other wise (see picture 2)

It shows “aan” → the flow is started"
it shows another “aan” → when I push the button again within 10 sec.
it shows “flow beëindigd” - the first instance of the flow is completed
it shows “flow beëindigd” again → the 2nd instance of the flow is completed.

Is this correct? (a flow can be started again before it is completed)?
Am I overseeing something?

Thanks a lot!!!

Yes this is very well possible.
You can trigger a flow every second, and have the action card delayed by an hour.

Homey even has a built-in sensor which disables flows with more than 60 running instances. Meaning, when a flow is triggered over 60 times, and 60 ‘copy’ flows were not finished yet.

Flows are run in seperate instanses for every trigger.

If you want to avoid that you may use Advanced Triggers app and set the execution to sequential.

Thanks Anders,
I understand that is available for Homey Pro only? (I have the Homey bridge + cloud version)
But good to know for future upgrade :wink:

I guess it is only available for Pro, but check whether the app is possible to install or not.
I do not have the bridge, never tested.

Another option is to set a logic variable like “Flow_Is_Running” to true once you start the flow the first time and set it to false once it has finished. And at the beginning of the flow stop execution if the logic variable is already set to true. So all additional triggers will be ignored.

bit late ( scrolling thru topics )

but for this the easy part is ( on pro ) the app coundown
CountDown | Homey

for example :
if push on switch , start countdown 1 with 300 sec
if the countdown is at 30 sec do B
if the countdown is empty , do C
if push on switch again , reset countdown to 300 sec
if push on other swich.. stop countdown…

i have made several lightning plans with countdown
for example bathroom
if sensor is active – countdown A start with 300 sec
if Sensor is ative again , and lights are on , reset countdown to 300
if countdown is empty , turn off light

so wen i am in the bathroom for 10 min and leave then , at least after 300 sec the lights will go out
wen i am in the shower, lights remain on , because of the continues reste of the countdown till sensor is off and countdown is empty …
