I became interested in high precision GPS time after listening to a podcast about network clock synchronization on Signals & Threads. My original goal was to setup a local NTP time server that I could sync all my devices to. However, I got sidetracked along the way – and this is the story of my Raspberry Pi home dashboard.

For Christmas, I received a GPS receiver for my Raspberry Pi. It ended up in the box with the rest of my sensors, add-ons, and screens I’ve bought for my Pi. It was a sad box. I decided enough was enough and that I wanted to hook them all up at once. So I built a dashboard with a module system so I can add and remove sensors and functionality as time goes on. The code is open source and has a Windows 98 theme powered by 98.css. It currently has:

The dashboard is part of a mono repository that also contains the client code which runs on the Pi. The Pi spawns a thread for each module which polls the relevant sensor and sends the result to the server. The printer module is a special case in that it also fetches messages from the server and sends a confirmation as they are printed. The other modules just fling data up.
