Description of Change

CHAD-14452

TVOC measurements are typically under 1 ppm for normal conditions for indoor air quality (see here). Rounding to the nearest 0.5 ppm is therefore not the most accurate representation and ppb should be used instead.

Summary of Completed Tests

See testing info in the ticket as well as new unit test.

These changes should be ported to matter-thermostat as well
Nevermind, I'm blind

[hcarter-775]

with the testing noted here, this looks good to me 👍
