Run flow for X hours

Is it possible to start a flow, and add a timer that stops it after x hours? I have a flow that i ordinary runs all the time, but sometimes when i go to bed i want to start another flow, and then after maybe 6 hours, i want i to go back running my “ordinary” flow. How can i do this?

Sure, there are action (then) cards to disable a flow and to enable a flow.
Search for “flow” when adding an action (then) card.

Take a look at Chronograph App voor Homey | Homey or CountDown App voor Homey | Homey where you can set a timer and react when a timer has finished.

If you have a fix time slot when the flow has to run every X minutes/hours you can do it like this:

You can also add a condition cards like oysf is awake.
