History graph is not continous?

I’ve set up the speedtest.com integration on my HA, and I’ve made an automation to trigger the check every 20 minutes (instead of the default 1 hour).

However, now when I check on History > Speedtest Download entity, I see the graph with the values with breaks on it:


Though the measurements are indeed taking place every 20 minutes.

This was not happening before when the check was done on the default “every hour”:

Can someone point me to the reason why this is happening?

Thank you in advance!

So it seems like it was a problem on speedtestdotnet integration, struggling to cope with speedchecks on peak hours (at every 00 and so). Actually putting a delay onto my automation made the trick and now it’s continous!

I’m marking this as “solved” (for the time being!)
