Shortly after publishing this project, I started getting random lock-ups with my temperature sensor controller/code. Been working on it since and ultimately got it working longer-term by getting rid of SYSTEM_THREAD(ENABLED) and the associated internet/cloud/mesh connection code. However, I'd still really like to have it work by only connecting to the mesh network (as opposed to requiring an internet/cloud connection) and will keep working on getting there. I'll update here and on the github once I hopefully get it working the way I'd like.
