Error fetching data question

Configuration
1

Hi

My log is full of errors like this but the strange thing is that the sensors still works.
furthermore its a scrape sensor not a rest? so I don’t get that part either.

I’ve defined 4 scrape sensors in a row that are trying to pull information on the same website, you see 2 of them below this page.

Could it be that these 4 requests to the same URL are too many at the moment?
Can I somewhere define different pull moments in time? Because I now lean on the scan_interval of HA.

Hi Bowa,
I would expect you could stop the errors by adding availability test.

Thanks, but shouldn’t you tackle the problem at the source? so what I had in mind was that maybe because I fire 4 requests at the same time to the same URL, that could be the cause of the errors, so I rather should do something about that first?

I say that because you seem to get the data much of the time, and you have a 5 minute interval so you are not personally overloading anything.

It’s a scrape sensor, it will not always be successful. (In my opinion)
