Describe the bug
Occasionally sensors seem to be reporting unnaturally flat temperature logs for a period of time.

For example:

image These are easy to spot because other sensors monitoring the same location do not reflect the same:

The flat sections appear on the sensor app too:

Unsure if this is purely a sensor hardware issue or there is some interaction between the sensor and CCA causing them.

Needs investigation of sensor data without CCA involvement to see if any instances occur in that configuration too.

To Reproduce
Steps to reproduce the behavior:

  1. Run a bunch of sensors for a while
  2. Monitor data and look for flat sections (easiest in dashboard)

Expected behavior
Temperature logs are not unnaturally flat

Smartphone (please complete the following information):

  • Device: Samsung Galaxy Tab A7
  • OS: Android 14
  • CCA Version 0.5.7
