How Can I Add a Timer to My Home Assistant Dashboard?

[patent shadow]

Hello everyone, I had an idea. I want to create a timer in my HA dashboard, so that when I click the timer icon I can set a duration, and when the time is up, my lights turn on or something else happens. Does anyone know how I can do this? ChatGPT hasn’t been very helpful so far. :/

I have not used it myself but it sounds like this might be for you:

Nice the Timer works, but how can i link it with an action, when the timer is finished?
