Winter came a little early in the mid-western US. On the plus side, that's meant we've been building fires and I've been able to further test and refine this project. I've been updating the temperature & fan speed set-points as well as playing with the sleep cycle times to see how it impacts battery life (so far I'm in the multiple weeks realm of battery life, would love to get to months). No finalized code yet, but I will update when I'm done tweaking it.

In regards to the lock-up issues I've experienced with the temperature sensor, I'm still working on this. It seems likely that for the foreseeable future I'll have to use the cloud connection instead of solely the mesh connection.
