I'm using Memmaid. Also tried SKTools with similar results.

BTW, I'm not overly concerned with the current CPU usage, just noticed a difference and thought I'd let you know, in case it helped narrow down the problem.

Much better hysteresis with 3-point history.

Resists going dim, but will still do so in ~9 seconds if ambient stays dark.

Hi, NuShrike, nice app, but does not work for me.
The problem is that in the full darkness the signal level from light sensor on my TP is falling under 7, but then slightly increasing till 7.26 (according to G-Light measurement) and stay constantly at 7.26 forever!
Since screen is dimmed and then lighting up to the level 3 again!

Is it possible to change the bound from 7 to 8 or make an ability to adjust it personally through some config file or command line parameter?
I suppose it might be useful to the people who have very little sensor signal in the darkness, too.

I think your 7.26 is the calculated lumen value that G-Light may be using out of the .net SDK.

I'm not using that SDK, but basing off the raw values coming from the light sensor almost directly. I can add build some registry entries to allow some tweaking because maybe each TP reads differently.

So holding your thumb over the light-sensor and the backlight still goes back up to 3?

Yes, right. Right now after my thumb covered light sensor it is dimming to 1, then after a few seconds it's back again on 3!
G-Light is deactivated this time, but when I start it showing 4.52 immediately after covering sensor, and 7.26 a few seconds later.

Yep!!! Please! Do it!

[mioqiu]

download it and will try .

[NuShrike]

Okay, I've verified that LevelSight stops running after a full-night's sleep. I'll see if the conversion to a service will keep it running.

Exactly the same for me.

I look forward to the next version, thank you for your efforts!

[NuShrike]

Now converted into a Service and runs under service.exe.

Registry configuration for fuzzy low and high water marks for turning auto-backlight on/off in
HKCU/Software/Creative 'Ware/LevelSight:

• low_wm: ambient level where auto-backlight turns off
• high_wm: ambient level that triggers auto-backlight on

Also, light sensor I2C device driver is now directly accessed so HTCSensorSDK is no longer used nor required removing a battery/cpu sucking layer.

It seems i understood the reason of program "malfunction".
It was caused that i did not read decription carefully:

But i had default backlight level set on 4! Thus, when ambient illumination was dropping under level 3, auto-backligh was turned off and backlight was increased to 4

Not i set default level to 2 and all is working well!
