Weather Station¶

This project is about replacing this commercial weather station from Germany:

Unlike this rendering, the real thing is virtually unreadable without shining a light on it ...

It synchronises to the German DCF77 time standard, shows the (local) weather predictions for the next 3 days (also via DCF77), and shows inside + outside temperature and humidy, picking up the 868 MHz RF signal from an external sensor.

I'd like to replace it with my own home-grown gadget. The hardware will be based on a 2.9" ePaper module, an STM32L052 µC, an RFM69 radio module, a DCF77 receiver module, and a LiPo or LiFePo battery. The software is going to be based on JeeH (of course). This should be a good test case for ultra-low power software design.
