There is something about auto temperature sensor calibration in excellent

Supposedly, just wait until the light is at room temperature and do factory reset and the sensor will be calibrated. I do not understand how that works.
There is no "auto" temp calibration of Anduril, 1 or 2. It must be manually performed, and a reset won't accomplish it.
Anduril is amazingly capable software for running a flashlight, especially considering its fundamental UI is based on a binary on/off switch.
But, it's best suited to hobbyists and requires some effort to get the most out of it, including checking the basic calibration for the temp sensor, and the voltage sensor (added in v2).
The pilots here will tell you that there can be consequences when their instrument readings don't correlate to the actual conditions. The stakes with a flashlight pale in comparison, and absolute accuracy isn't necessarily required, but the correlation should still be verified, and it's one of the first things that should be done so that the light performs as expected.
Those who aren't inclined to dive into the nuances of an open-source project, keep up with its revisions, or parse the sometimes sparse documentation, should be wary. And that's before considering it is subject to bugs as well.
Still, at least if there is any doubt, or good questions, the developer, TK, is accessible on the light forums. Her input, and documentation, is the ultimate authority.
