I created a custom local application the reports the temp and humidity of sensors around my house. Anytime temp or humidity changes I push a new image to the Tydbyte. The problem is I can only fit r lines of information and wondered if there was a way to pause like 5 seconds and then display a second page of info without having to create and push a second image to the Tydbyte?

Here’s the image and code Im using…

Yes, you can!

If you check my Product Hunt app, I display 3 screens for almost 5 seconds each:

The trick is to create an animation.Transformation to hold the widgets for each screen where the only important thing is the duration attribute, you’ll see that the keyframes array is empty. And finally you use render.Sequence passing an array with these transformations.

return render.Root(
    delay = 100,
    child = render.Column(
        children = [
            render_header(),
            render.Box(height = 1, width = 64, color = "#fdf0ee"),
            render.Sequence(
                children = frames, # frames is an array with 3 transformation objects
            ),
        ],
    ),
)

You will find other approaches if you look at other community apps, but this one has served me well.
