7.4" E-Ink Shelf Label used as a Weather Station

Huge thanks to Aaron for joining the project. He was able to extract the stock LUT from the flash and get vibrant back and yellow colors. You can find a link to his Modded GxEPD library in the discussion section.  I already converted all of my displays to the ESP32, but Arron has many more to play with. He was able to program onboard CC1110 processor with a custom firmware and exercise RF module.  The RF module is bi-directional, so we can dedicate one unit to be a bridge with others. The battery-operated units then can register periodically and download the rendered image. I wish we all could get more of those displays.
