Remarkable

I bought an old remarkable with the idea of using it as a display for my homeassistant (home automation platform). Ideally, I’d like to write a program that wakes up every minute or two, polls my HA instance for sensor data/whatever, sets a sleep screen to an image of helpful data, then goes back to sleep to save battery life. I’ve tried searching, but can’t figure out if there’s a way to do that. Any suggestions?
