Trend Platform, low rate update

Screen Shot 2021-10-23 at 00.57.47

I am using platform TREND and I created a template sensor to use the attribute gradient, the problem is it updates every ≈90s, but the sensor what it is tracking it is updating every 30s

I need faster updates, how I can get it?

Have you tried tweaking the max_samples & sample_duration variables. That mighty allow you some customisation.
