Screensavers

In flows, you can only change an animation of the LED ring (which is limited in time by definition).

You can set a new screensaver from a flow.

I stand corrected

If you can move 1 led around the ring then you can also do that whit 2 led's and so on, I think.

Yes, but I cannot make 16 million different screensavers (255^3) for all the possible colours. Or well, I won't.

TheoDeKoning

That is perfect understandable Koen. 
It was more that I found it odd that it was not possible.

But the colours of Dutch flag is maybe an idea?

Already did that a while back. See this post with video. It's not very well visible though.

Might be possible to add an action card where you can select a color that is passed onto the app as a variable?!?

AFAIK, the app registers the screensavers upon initializing, and I haven't found a way to change the screensavers after this initializing (except for restarting the app or Homey). If this is possible, I could add settings, but also change of motion in time (i.e. a real TIFF screensaver).

We need an working example for the animation.updateFrames() method. This seems to allow to update a screensaver after initialization. Would be great if it would also take parameters. You could update it with whatever you feed it. @Emile , could you shed some light on how this works?

animation.on('screensaver_start', function( screensaver_id ){
    // We can even update the frames when we want. In this case, when the weather has changed.
    animation.updateFrames([ ... ]);
})

KoenMartens

@Phuturist : Yea, that's what we need. I asked Emile for an example earlier in this thread, but so far no response

Read it here https://developers.athom.com/library/ledring/

But yeah, it looks like you can update only frames (with updateFrames), not options.
I guess you could hook this up with api.js or app2app https://developers.athom.com/library/api/

In theory, updating the frames should be enough: Leave the rpm on zero (non-rotating), and update the frames 30 times per second to get any animation you want (although it's CPU intensive I guess).
Haven't gotten it to work though.

That's a workaround, not a real solution. I feel a rewrite coming

A rewrite isn't necessary: one extra function (change RPM), and better documentation is all that's needed for complete functionality.

@KoenMartens the documentation has been updated but it's still very limited. Could you have a look and see if you can work with it. I lack the skills to convert this into something myself (I need working examples).

Im using the 10% brightness rainbow for a while now, just nice for an ambient setting. But since a few days I notice a difference. The colour transition is more 'hard' lined an especially the blue color is blinking when shifting a led. Can anyone confirm this?

Always been like this as far as I know. It's the reason I never made a rainbow screensaver below 10% brightness, as this 'blinking' will only get worse.

jimmy_zeropm

Hmmm, I've noticed that if you switch to the normal spectrum, and then back to the 10% modus, the ring is smoother and the blinking is gone... Like a little reset?

KoenMartens

Just tested and doesn't change anything for me. If it helps you though, great!

jimmy_zeropm

Yes it changed a lot, especially the smoothness...

jimmy_zeropm

Ok, try this:

- Set screensaver to 10% spectrum,
- Set screensaver to tiff
- Set screensaver to 10% spectrum, notice the ring
- Set screensaver to full spectrum and use the slider to set 100%
- Set back to 10% spectrum

Notice the difference in smoothness and bright colours... there seems to be a difference.

People who want more screensavers than this, try this app:

Great work Alex!
