Auto night Detection: Sometimes works, sometimes doesn't

[saipsa]

There is no reproducible steps, it is random. Fails 40% of the time.

@wridgers can you stop autonight and run it manually on the shell with the following: /system/sdcard/bin/autonight -v and see if you can capture a failure? Be sure to run it with the light sensor exposed to light and then covered (or in dark conditions where it should change).

[saipsa]

@jthwho I think I know why it fails sometimes.

I did like you said. current value and updated value were shown in output for few hours. Then it stopped. I think the process got killed or something.

@saipsa that means that your ssh connection died. Most likely your computer fell asleep.

[saipsa]

@jmtatsch you are right. But the output to terminal stopped minutes (hours?) earlier than that.

When day to night happened, auto night mode didn't kick in. The night mode should have kicked in if the auto-night process was not killed.

I started it from command line and auto-night kicked in after averaging 5 values.

[saipsa]

@jthwho after updating, now auto night doesn't start autonight values are >400 in complete darkness with IR LED off. Previously it would be <100.

[jthwho]

@saipsa That's odd. Can you post a run of autonight -v with 60 seconds of dark and 60 seconds of light? The autonight application hasn't changed in a few months, so I expect it must be something in the update that changed the values.

[saipsa]

@jthwho I can't :( bricked my device.

It seems that I've got a similar problem. In darkness autonight detects light and switches of the IR-LEDs. When this happens it records a weird value of 4193870.00 - probably a upper limit should be implemented?

Auto Night Mode is not enabling/disabling for me either

Messed around a bit and the light level seems to barely affect the value.

[aartrost]

@unmotivagedgene This happens because the new Dafang models do not contain a light sensor anymore. For more information see https://github.com/EliasKotlyar/Xiaomi-Dafang-Hacks/issues/332.

For the camera that does not have sensor anymore: can you test this https://github.com/EliasKotlyar/Xiaomi-Dafang-Hacks/pull/557 This is software detection night and mode

I am experiencing this issue on a Wyze Cam V2.

Any advice would be greatly appreciated, thanks.

Your camera probably doesn’t have a light sensor.

[Shadow00Caster]

@jmtatsch

Ya I figured as much, doesn't look like any of the software based solutions for detection are working. I will just do through other automation means using triggering night mode on/off through MQTT and using a LUX sensor.

[saipsa]

@Shadow00Caster you can trigger it using cronjob too.
