Hi @Roger_Gorissen,
as Arie already wrote, please post a screenshot of your flow.
I guess the problem is that you just programmed one way. And that is only from the point of view of the switch, and not from the point of view of the lamp(s).
The way back is probably missing. If at a certain time the x lamps are switched off, then the button must also be switched off.
Switch button on → switch lamp on
Switch button off → switch lamp off
Lamp is switched on (e.g. by time) → button has also be switched on
Lamp is switched off (e.g. by time) → button has also be switched off
However, a generell problem is that you switch several lamps. What happens if only one lamp is switched off/on (e.g. by a time setting or manually), but other lamps remain off/on?
This is a sample where you can control up to 5 dimmable lights, made by @Arie_J_Godschalk. I guess something similar has to be created for your case.
