Chronometer Helper

Start a chronometer (or a few) from a script or an automation, and show it in the lovelace.
We could easily and accurately monitor how long any entity has been in any state.
I know you can see the history or log, but I think it would be usefull having this chronometer in the lovelace.

Hi Macario Diaz,

This could mean a few different things…

but I was pretty sure you can do this with custom cards, but didn’t know exactly so I did a search for you.
Found this:
Stopwatch with start/stop/resume, lap and reset.
Found this:
Stopwatch Helper. (vote it if you like it)

Personally I don’t know if this is up to date, but it looks like what you are asking for as well.
Check it with caution,
but it pulls in some custom cards from GitHub using HACS to do that kind of thing.
