I doubt it's related to the MySensors communication. Are you using a Dallas temp sensor? Could you check that the is actually connected to the dallas sensor by using isConnected().
When googling your problem I found a few hits on -196.6 which is the error code (DEVICE_DISCONNECTED) converted to Fahrenheit.
Start debug mode (Config.h) to see what the sensor actually sends.
@zookazim so sorry I haven't been on here in years. I actually left the IoT nodes for a while. I was running into so many issues. To answer your question... not sure if it's still required or even relevant.
The bew error you got is discussed in https://forum.mysensors.org/topic/11448/config-h-39-first-defined-here/4
Easiest way is probably to switch to the development branch of mysensors.
Run git checkout development and then start over from the configure step. Or follow the step ”To use the development version with the latest updates” on the raspberry pi gateway build page.
