Building the GUI was not difficult at all. I first designed it in gimp and then converted it to code. The GxEPD library has an easy to use interface for displaying text, images, and geometrical shapes. The font I used is the GoBold , and the weather icons are feather icons

Adding the functionality was the difficult part. The plan is to use the weatherunderground API for weather, todoist for TO-DO list and a network time server for syncing time. All these details will be updated every six hours. The esp32 is in deep sleep for most of the time. It wakes up changes the time with a partial refresh and sleeps. Every 5 mins it does a full refresh to avoid ghosting.
