How to set up a timer with start and stop times from the UI

Does anyone know, how to set up a timer with start and stope times from the UI, like an ordinary digital timer???

Perhaps this one meets your requirements?

That is not exactly what I am looking for. I search for something like:

Start-Time: 00:00
Stop-Time: 00:00

On/Off

Start- and Stop-Time should be adjustable via UI.

Bin gerade in einem anderem Forum (KNX-user-forum) auf die HACS Integration Scheduler aufmerksam gemacht worden.
Werde ich am WE mal probieren.

Two input_datetime helpers and an automation with two Time Triggers. What is the automation turning on/off at start/stop times?

Its not a timer but a scheduler card might help?
