In the fall of 2019 and spring of 2020 i had a soil probe set up at our farm that sent temperature data to this page. On May 5th, it was stolen. I replaced the parts and tried multiple times to get the new sensors to work. On 2/9/2021 I found a new library that actually works as expected. The probe is sitting at my daughter's house monitoring temps in her garage and in an adjacent crawlspace under a bathroom with poorly insulated pipes. We have an electric heater running to heat the area. The temps are uploaded to the webpage via a cell phone connection using a Particle Boron.

The weird spikes and valleys are a result of malfunctions of the device, taking it home, modifying the program, etc.
