How to change or disable motion detection at night when camera is very grainy

[ptr727]

My cameras automatically switch to night mode when dark, but this causes lots of grain and motion on some older cameras, and worse my back yard camera points at landscape, and decorative WLED lights that constantly trigger motion.

I added exclusion zones for the WLED lights, but any reflected landscape or interior light still causes lots of grain motion.
If I change the sensitivity way up, I then loose motion sensing in the day when the camera switches back to day mode.

Is there a way to change or disable motion per camera, per astrological clock, sunset +-x sunrise, when the image looses color, when grain increases, or some other way?

E.g.

The easiest way to disable motion detection dynamically is to use the MQTT integration:

https://docs.frigate.video/integrations/mqtt/#frigatecamera_namemotionset

Just send "ON" or "OFF" to the frigate/<camera_name>/motion/set MQTT topic.

You can also adjust motion detection threshold and contour area dynamically via MQTT:

https://docs.frigate.video/integrations/mqtt/#frigatecamera_namemotion_thresholdset
https://docs.frigate.video/integrations/mqtt/#frigatecamera_namemotion_contour_areaset

If you use Home Assistant, there are also switches available to use with the official Frigate integration.

Ok, thank you, HA integration is next on my list of things to do, time permitting.
I was hoping for an easier direct way e.g. time/chron -based motion enable per camera (that is what I use in my current NVR).

Right, Frigate doesn't implement this directly - HA, Node-RED, and other popular automation platforms can do this very well already. We didn't want to reinvent the wheel 😁
