EPClock

ESP8226 Arduino based ePaper clock, using NTP and showing the weather.

Using a Waveshare 4.3" UART module and an ESP8226 R1 Mini from Jaycar Australia, which is a D1 R1 in the Arduino program.

The ESP8266 doesn't really have enough RAM to be able to parse the XML available from the Autralian Bureau of Meteorology, so the bom_xml.py script does that and spits out some simplified json I've put that json on my home web server, and set the script to run hourly.

I've also put in bom_rrd2.py which uses the 'weather-au' library from pip and also pulls some current temperatures from some MQTT sensors I have around the house.
