That's what I want to do. My idea is to use mqtt for the sensor to send data to an android tablet; the tablet would be an mqtt broker. The tablet is always on unlike the computer. Then the e-paper display can fetch it also using mqtt. This would allow me to have more than one display fetching the data.

Here's another display library. It's written for the arduino but that shouldn't be a problem since the esp32 can use the arduino api. I want to try and use espressif's idf api instead of the arduino one.
