How can I get a more precise / higher frequency timeline for a sensor?

I try to make a template sensor turning on my washing machine template-sensor when it starts, and off when it go over to just rotation.
To achieve this I have to analyze the power consumption over time in detail.
The problem is that the Home-Assistant sensor is not very detailed at all. Small graph and it looks like it just storing values every X minutes or so.

I need every second in a big clear graph. It does not hav to be all-time monitoring like this, just 3-5h.
How can I achieve this?

Why do you need one second resolution to determine when your washing machine is finished?

Just trigger on the power going below 50W for a minute.

If you click on the header then the graph will expand.

By the looks of it you have a long history saved, reduce that to a day (or less if possible) while doing the test and the graph won’t be as compressed

hmm, looks better, i did not know about that. still a little hard-do-read

The on-trigger is easy, the problem is off-trigger

Mark your graph where the off point should be and I’ll help you with the trigger.

Then open the history and select the entity, and time interval you want to look closer at

I am on a good way now :slight_smile: Can I make it higher in a way to se the difference in value better?

Not that I know…
But you can put the mouse pointer on the line:
