Change by timer

Hello all,

I am an absolute beginner and need your help. For example, I would like to change two images in the dashboard every 3 hours. How can I do this? greetings ben

Welcome aboard.

Give us some clues… Where are these files stored? On your HA machine? Via an online URL?

Are these just random images or do you have a fixed list of images?

Hello, for example two different letters would be enough for “Right and Left” which change after 3 hours.

Do you need exactly images of R and L letters?
Can’t a real text be enough?
Where are you going to display these images?
What is a condition for displaying a particular image? Just change every 3 hours?

text would be enough as well… it would be perfect to see this “cards” in my ha dashboard/app… condition is only the timer of 3 hours. thank you!

On which card do you need to show these R & L letters?

i thought i could do just add a card on my dashboard :cold_face: … not a specific one

There are plenty of possible alternatives, depends on what you need.
For instance:

  1. Create a trigger-based template sensor (trigger = every 4 hours) which has two possible states - “Right”, “Left”.
  2. Add this sensor on an Entities card.
