Template/Skeleton to make integration for sensors + camera

I have made improvment in WorldTideInfo integration. I slow down the refresh rate towards server , and put higher rate into display.

Now I would like to implement it in asynchroneous. I wonder if there are templates/skeleton (or kind of receipe) to implement integration with sensor+ camera.

To be efficient , I would like to implement :

  • one sensor (to retrieve to tides data)
  • another to display data at an higher rate

In config flow, something to store the API key, and add entry for each location you want to see.

So are there some templates ready to implement ?
or is there anyone that can advice me ?
or a kind of tuturial to make a project from scratch ?

Thanks in advance
