After seeing this, the IKEA CORRAS server rack in my living room needs a similar tasteful e-ink picture frame sitting atop it, for system status and general info.
That's 16 seconds to update the display. I am familiar with the Kindle etc but this seems very long. I guess it doesn't matter too much for ambient display projects like this.
This e-ink component includes red (for alerts): https://www.waveshare.com/12.48inch-e-Paper-B.htm
