A tool for developers who make their own images. When your TRMNL ePaper display checks in, we call a URL on your server and pass its answer straight to the device: where to get the image, a filename, and how long to sleep before checking in again.

That means your server decides what shows and when, on every check-in. The image address can change on every request, and can even sit on your local network. Send the same filename twice and the screen won't redraw, which saves flicker and battery. Sleep time is up to you, down to 1 minute. Already using Alias and want more control? This is the next step up.
