I finally found a way to do remote page-turning for Kindle -- something I was trying to do for years. It does mean I have to read books on my Android phone instead of the Paperwhite. With OLED and white on black, I find it's pretty all right though. But I can finally rest the reader somewhere, on my knees, on a pillow, whatever, and click a remote button to get to the next page. Freedom!

You enable volume button page turning in the Kindle app settings. This already means you can attach e.g. a USB keyboard to your device and use its volume buttons. But you can also use these tiny BTLE media control gadgets[1], meant primarily for putting on steering wheels of cars that don't have built-in media controls. The replaceable battery lasted a couple of thousand pages so far, which is kind of amazing. Note that the volume buttons of bluetooth headsets do not work.

I've never understood how this isn't a standard feature with standalone Kindles. People made it work using the USB port, but you need to install a custom ROM. It makes incredible sense for accessibility purposes, alone. Imagine a big fat button for people with limited limb control, or something based on eye movement for people who are even worse off.
