Derivative sensors — no more average over time option?

I swear that last week, Derivative Sensors had an option to make the value a rolling average over time. But… now it doesn’t seem to?

Am I crazy?

Yeah. I restarted HA and they came back…

FWIW other people are reporting this problem at :shower: Bathroom Humidity Exhaust Fan

There is also a major problem with derivative - it does not become zero when a sensor is not changing.

OMG, yes. This explains why “derivative” sensors don’t look like derivatives at all, but rather inconsistently-scaled versions of the original.

This bug seems to be rather old.
Wanted to create my own derivative sensor (some template sensor), cannot manage to begin…

Still Nothing? Is this problem abandoned?
