ESP32 Weather Calendar

Overview

Key Features:

This project uses ESP32 to access Xinzhi Weather (https://api.seniverse.com/v3/weather/daily.json) and NTP date, updating approximately once daily around midnight. The data is displayed on an e-ink screen.

Battery consumption only occurs when accessing WiFi and refreshing the e-ink screen. However, ESP32 operation mode consumes more power; a 200mAh battery lasts less than a month
with daily wake-up for automatic refresh.

Project Deployment Tutorial

: Arduino is used; I used VS Code + Platform.io for easier compilation.
You can also apply for a Xinzhi Weather API account; the daily free attempts are sufficient.
Install the ESP32 driver
, compile, and flash
