Hey Cyb3rGlitch would you please add tasker variables? I think it would be awesome extension for Tasker.I have already tried to set up Tasker to change my profile to 'Night' with specific condition (after*21:00 PM*with given lux level). However the %Light turns out the value only when the brightness change. Therefore it simply will not work properly if you are in complete darkness, because there is no brightness change.

If we have %Lux_brithness variable which keeps current lux value we will have a possibility to use it as a trigger in Tasker. In this case I could create the following profile:
If %Lux_brightness = 10 lx -> change profile to 'Night' (using plugin you have already done).*

Cheers,

I'll add them during the next major update later this year.

Will there be an update soon?
There will be a minor update soon. Only beta testers are receiving updates at this point.

That's awesome! I know I should not ask for ETA but I hope it will be soon :)

As for beta, I should think about it. Thx for the tip.

Tried this a while ago when I had an EVO 3D and it worked poorly, I think the light sensor on it just sucked. Well I've got myself a shiny new Nexus 5 and it's working much better. My main issue is with the "sub-zero" brightness, which apparently just darkens what's on the screen and doesn't actually dim the backlight any lower. I know this is possible with a rooted device, I've done it in an app I've written. Will it be possible with a plugin?

It'll be possible once RGB control is possible. If you know a way to do it on the Nexus 5 I'm all ears.

Do you have an open beta or is it closed only?

I am trying to set up my friend's lux setting for him on his nexus 5 and can't seem to be able to understand how this fully works.

He has purchased the full version and has asked me to set it up for him since I'm the one that told him to use it, but I am having trouble understanding exactly how to do this.

I don't fully understand what I do with the actual phone settings for screen brightens, but I am assuming I simply leave it at 100%.

But then I when I bring up lux I don't understand what exactly is happening as the only thing that effects the screen is when it goes on the Sub-Zero side...but when it over the zero mark and into the positives then it makes no difference at all.

So example would be.
If I leave phone brightness settings at 50%.
Then I enable lux and try to adjust the screen brightness with it and all it does is this.
From -99 to Zero it adjusts screen brightness..But from Zero to 100% it does nothing pretty much.
In this case when I am at 0% in lux birghtness, the screen is at whatever the actual phone settings were set at, meaning at 50%,,,and when I go below the Zero mark the screen will darken and go into sub-zero,,,BUT if I go ABOVE 0% absolutely nothing happens. The screen brightness does not adjust at all from 0% to 100%.

So what I am understanding here is that lux is either in Sub-Zero brightness, or it is at whatever I have the phone settings adjusted to.

I thought that anything ABOVE 0% would control the phone brightness, meaning if I have left the phone settings at 50% that lux would adjust the brightness from 50% to 0% of the settings of the phone,, but then if I go below that then it would dim even further, meaning Sub-Zero.

Right now what I am saying is that lux does nothing to the screen when above 0%, and only dims at below 0%

Is this correct or am I missing something...Doesn't seem right to me

So if i try to link a certain lux with a certain screen brightness level and that brightness is above 0%, then it would make no difference if I chose 5% or 75% as the screen is exactly the same brightness at both considering I am above the 0%

This is not how lux should behave. Lux manages your screen brightness from sub zero to 100%. I don't know the solution to your problem but I can confirm there is a problem.

Thanks for confirming. . I feel responsible for recommending this to my friend and not be able to fix it.

Hopefully the developer comes in soon

    App Description

    Lux isn't your ordinary brightness app. It intelligently adjusts the brightness of your display based on the environment you're in. If, for example, you step into a dimly lit room, Lux will automatically lower the brightness of your display to make it not only comfortable to read, but to also preserve battery power.
    Lux provides the option to automatically adjust the backlight at fixed intervals (periodic mode), when a change in environment is detected (dynamic mode), or when the phone wakes from sleep. It's also possible to adjust the backlight manually. Simply disable automatic mode and you can use it like a traditional brightness tool!
    Perhaps the best thing about Lux is that you can teach it how to behave. If the backlight is too bright or dim for your liking, simply open the provided Dashboard, adjust the brightness slider to the level you desire, then hold the link button. Lux will use this new 'link' as a reference in future.

    Give it a go! I want you to test Lux for more than the 15 minute refund period offered by Google. I understand that some devices may not have the best quality light sensor, and that you may need more time to play around with settings. If you find that Lux doesn't suit you after the 15 minutes is up, you can request a refund at any time via e-mail - no questions asked.

    Lux Low-Level Plug-ins

    Soon Lux will support plug-ins to bypass Android API limitations. These plug-ins serve to replace the overlay system Lux uses to make adjustments for Night/Astronomer modes and brightness in general. The plug-in library is free to use for non-commercial development, and can be found here:

    Lux Plug-in Library | Nexus 4 Sample Plug-in Code

    How to make a plug-in

    There are two approaches to making a plug-in for Lux. The passive and the active method. The former is as easy as providing a set of superuser commands for Lux to interpret and apply. These command correlate to functions such as setting pixel RGB or brightness levels. This is the type of plug-in the Nexus 4 sample linked above takes.
    The active method requires you produce your own code to perform RGB/brightness adjustments. This might include importing a device specific library to do the heavy lifting, and then returning empty superuser commands back to Lux.


    Getting Started

    Simply import the Lux Plug-in Library source into your IDE as an Android Library Project, and then create a new Android app which extends PassiveDisplay.java.

    PassiveDisplay provides hooks into Lux's plug-in framework, which you can use to provide superuser commands for Lux to execute. These commands correlate to functions such as setting RGB values. Take a look at the sample Nexus 4 project to see how it's all done.
    Finally, in your new project's AndroidManifest.xml file, add the following:

    Code:
        <activity
            android:name="com.vitocassisi.lux.plugin.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
    
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    
        <receiver
            android:name="com.vitocassisi.lux.plugin.LuxBroadcastReceiver"
            android:exported="true" >
            <intent-filter>
                <action android:name="com.vitocassisi.lux.plugin.search" />
            </intent-filter>
        </receiver>
    
        <service
            android:name=".[B]MY_PLUGIN[/B]"
            android:exported="true" >
            <intent-filter>
                <action android:name="[B]YOUR_PACKAGE_NAME_HERE[/B]" />
            </intent-filter>
        </service>

    Be sure to replace YOUR_PACKAGE_NAME_HERE with the name of your plug-in's package, and MY_PLUGIN with your extended PassiveDisplay class.

    And that's it! Now you're ready to test!


    Enabling Plug-In support within Lux

    To enable plug-in support, you must check 'Enable plug-in support' in the Advanced section of Lux settings. Enabling this option forfeits all responsibility of mine for any issues caused while using Lux. Plug-in's can cause very real damage to your device if they're written incorrectly - don't use plug-ins from sources you don't trust!
    Testing your plug-in
    Testing is critical for creating a good plug-in. You are dealing directly with system files, and can easily cause damage if you do not know what you're doing.

    DO NOT RELEASE A PLUG-IN WITHOUT TESTING IT ON THE TARGET DEVICE FIRST!

    Ensure that the following work with your plug-in installed:
    • Astronomer Mode
    • Night Mode
    • General brightness adjustment
    • Lux readings functional

    BE METICULOUS WITH YOUR IMPLEMENTATION OF isSupportedDevice()!
    Modifying system files on the wrong model/kernel may cause irreversible issues!

    Hey everyone. Sorry to hear that people are having issues with the paid version. I'm working on hotfixes at the moment. A lot of these bugs don't appear on my test devices, which is why regressions happen seemingly randomly. I'm working hard on finding a reliable way to reproduce and test these issues to prevent this happening again.
