How To fix a hardware problem with software!
Ten years a go I installed a Fine Offset weatherstation and it's been running more or less continuously since then, 24/7 , feeding data to the internet to provide a Blakedown weather report. The weatherstation itself is shown above. It links via radio link to a display panel in the sitting room, which shows current weather data. The panel also links to an old XP laptop running a piece of software called Cumulus, developed for free by a weather enthusiast and used worldwide. Cumulus takes readings every ten minutes and generates a monthly log file, as well as website pages that are available from my server at www.mecol.co.uk/weather/index.htm . A few months ago the pressure reading stopped working and I finally decided to try to fix it. As it happens, for reasons I won't go into here, I have a spare station that I've used over the years for parts. So I swapped out the display unit (which is where the pressure sensor lives). To my surprise the pressure still didn't work
