Interactive temperature probe demo

Simulate garage probe readings by changing outdoor temperature, sun load, and door state. See live JSON output like the real monitoring feed.

Move the sliders to mimic weather and garage use, then compare how three probe zones and their average respond. Readings refresh every two seconds with small random noise—similar to how real sensors jitter in a live feed.

For background on placement and interpretation, read temperature probes and their uses and temperature changes and what causes them.

Garage conditions

Adjust the environment and watch three probe zones respond, just like the live JSON feed on the home page.
