Preserve last calibration results between reboots

Is your feature request related to a problem? Please describe.
The calibration process requires some stable and predictable conditions.
The auto-calibration feature is useful since it allows to simplify the sensor setup.
Periodical re-calibration makes sense to adjust expectations to the changing environment.
Automatic re-calibration on boot is unpredictable.
Describe the solution you'd like
Preserve calibration results in some way. And don't perform automatic calibration on boot if data already present.
Re-calibration can be performed on schedule via the exposed service.
Describe alternatives you've considered
Use manual calibration (e.g. turn-on automatic method, grab values, fill into config).
Downsides:
- each time sensor boots with some default values unrelated to the latest calibration results
- more manual work
I'll work on this. It goes hand in hand with the sensors refactor I'm about to start.
@CarsonF This should be an optional configuration option.
This should be an optional configuration option.
As in not the default functionality?
Yes the default should be false
because i know that it can cause problems. Thresholds change by a lot depending on the sunlight and temperature. If you dont recalibrate for quite some time you getting worse results.
That makes this the opposite of #58 then. Maybe we should discuss more.
@Lyr3x but this feature only prevents the re-calibration on boot. So in the described scenario disabling it will only help if you are rebooting the device regularly.
Although I agree that it can be configurable.
I think most of the users do reboot frequently to update the firmware and use the chance to get fresh thresholds in. I do understand why some don't want to do that always though
