Currently it is quite cold in New England, Google says about 28F in my home town. Our house has a wood burning stove in the basement that we like to keep burning so the room is about 70F. With the help of some python from Mikal Still, and some left over one-wire serial experiments, I have a working prototype to keep an eye on the fireplace performance.
A bit of Python polls owserver using a SWIG module and commits the read temperature value to a MySQL database. I munged some of Mikal’s graph server code to simply post the chartserver URL to appengine so it could be hosted for the world to see.
