Enabling triggers and actions causes high CPU

[wyohman]

Under Trigger -> Control, when I enable this function, Python does this:

If I disable it, the CPU returns back to normal. Any ideas?

Hi,
you are running a Pi 3, right?
Unfortunately, I don't have this model for testing.

On a Pi 5, with 'Mean Square Diff', it looks like this:

Motion capturing was started at about 19:20 when the number of threads used by raspiCamSrv rises from 6 to 21 (lower left chart).

When no video is recorded, raspiCamSrv uses ~2.5% CPU which increases to ~11% during video recording.

Extra memory consumption (upper right) is not really significant.

Extended motion capturing algorithms consume more CPU, depending on the algrithm (see Performance). Probably this might overload a Pi3.

In general, motion capturing analyzes frames from Live View.
If you reduce the Stream Size for the live View, this should also reduce performance requirements.

I'm running a Pi 3B+

I dropped my live settings to this:

I'll test and see what happens. Thanks again!

Is your dashboard using Telegraf and Graphana?
