Kindle weather page

This project consists of three distinct sub-projects:

1) The Tablet Weather page, shown above. This is a standalone project. 2) A client that runs on a raspberry pi zero or pico (or other microprocessor)

• serves a static web page served by a webserver running on that pi (lighttpd on Zero, custom server on Pico) which retrieves the JSON file described below
• a script that periodically updates a JSON file containing the latest data
• a script that periodically uses the Mosquitto MQTT client to publish the latest data
• both the periodic updates are controlled by a CRON script These scripts can read temperature, humidity, air quality, air pressure from a BME688 sensor; temperature from a 1-Wire temperature sensor (based on the DS18B20 sensor chip) 3) Seperately, a centralized server app periodically retrieves MQTT observations and writes those to a RESTful database service
