Architecture

Battery powered Arduino, communicating with a RasberryPi over nRF24L01. Pi pushes status onto a Redis queue, monitored by a server that logs events to a database for stats, and pushes change notifications on another Redis queue, used by the webserer to push notifications to browsers using websockets.
