Override Flow from HA Dashboard

I have tried doing a fair amount of searching, and maybe I am not keying in properly, but as I get started in setting up some automations in Node Red, I want to ensure I am setting myself up for success down the road.

I have started basic:
Big Timer - Switch Node < service on and service off (Using a simple hue go light, or two table lamps in bedroom) This has gotten me used to some of the basics.

Now that I have used the flow a little, I realize there are times I go to bed, and need to turn off the lights before the timer end time would typically be. I currently have 4 “input” nodes that feed into bigtimer, on, off, auto, manual. I can pass the OFF override, and it will continue to keep the lights off until the next run time.

Q1 - It would seem an input boolean is the proper way to add an element to my HA Dashboard to replace these input nodes via Node Red in which I can control from the front end. I am still quite new to HA as well and seem to be missing some things on this behavior, so any help is appreciated. (config entry to define the input bool, scripts to toggle, automations to toggle?, etc required to make this work) I would like to have an input bool on most automations which allows me to turn the entire flow on or off. This would then allow me to control these lights manually without having NR turn it back on during that time window.

Is there a way to pass a manual override and not disable the entire flow? IE if I wanted to pass OFF, but still have the automation stay active and trigger at the next execution time.

Hi Janis
Input Boolean would be correct.
All my motion sensor flows have an overriding input Boolean.
There are plenty of times that I go to bed before 11pm which is the time I set for my bedroom motion to stop turninh on the bed lamps. And there’s nothing more annoying than lamps turning on while your in bed watching TV at 10pm because I moved my arm.
With Node RED it will always help to post your flow. Makes it easier to give you assistance.
