I’m (hopefully) coming down this evening, and will be bringing an ESP8266 NodeMCU dev board ( @techfolderkites you might be interested) and a C.H.I.P. $5 computer (from Kickstarter) to play with (not sure if that’ll be easy to get going! )
Failing that, I might have a hack at my Network Rail feeds code because that might be entertaining today…
I’ll be down albeit a little late.
Having spent a big chunk of my day on the train, If the Network Rail system is anything like the Southeastern one then it’s next to useless. The BBC were reporting a tree on the line long before the SE system did…
https://github.com/esp8266/Arduino - install with Boards manager, code like you’d code an Arduino. Most things work, few things don’t! the Wire library should work fine, so I’d expect you can ready your sensors just fine
Let me know how you get on with that board I lent you, hope it does what you need.
