home.newts.org is a tiny Raspberry Pi Linux computer. Currently it runs pyweather to connect my Davis Vantage Pro2 weather station to wunderground.com. It also runs my tf mud client in a screen session and has a Cherokee web server that consolidates some information about the house and the solar power generation.


The page uses python to get XML data from the Vera Z-wave controller and thermostat and HTML data from the Enphase Envoy gateway controller.
