Ability to set adaptive 'ramp' up and down times

[lazyboy0172]

I'm new to AL but my understanding is that essentially my lighting color/brightness would go from Max to Min back to Max between sunset and sunrise. For example, if sunset is 5:30pm and sunrise is 7:30am, lighting color/brightness will begin lowering from 'max' at ~5:30pm, hit the 'min' value ~12:30am and immediately begin climbing again to reach 'max' again at 7:30am.

I would suggest an option in the configuration to set a 'ramp' time, so that while the ramp down still starts at sunset and ramp up ends at sunrise, the time it takes to get from max-min or min-max is no longer half the night but instead whatever hh:mm:ss that the user configures.

For example, if I set to 03:00:00 and use my sunset/sunrise times above, instead of slowly going from max to min from 5:30pm to 12:30am, it would go from max to min from 5:30pm to 8:30pm, hold at min until 4:30am, then ramp from min to max from 4:30am to 7:30am when the sun rises. This essentially just means we hit that 'min' value much earlier in the night and hold there for a while rather than just barely hit min values for a minute each evening while we're asleep.

The only problem would be what to do when the user sets an impossible ramp, e.g. sunset to sunrise is 8 hours today because it's summer but user has ramp set to 05:00:00 still from winter. do we A) respect the ramp down then jump up immediately to ramp up on time? B) respect the ramp 'rate' but after 4 hours start ramping up (i.e. AL never reaches 'min' values because before the full ramp down can complete the ramp up begins)? C) ignore the ramp config entirely for that evening and do the 'normal' behavior of max to min to max over the 8 hour 'night' period?.... Personally I would vote (B) but the point is that while this scenario complicates things it is a solvable problem.

I totally agree with this. It‘s mandatory to have any option to customize the curves for color temperature and brightness (e.g. to a full sinus curve).
Ideally this component would also take the different twilight phases into consideration.

I’m hoping this gets implemented into v2

[Kaot93]

I would love this too. Are there plans to do this?

[lazyboy0172]

I've seen this project get a lot of dev love recently so I wanted to chime in on this again. I don't believe anything like this has been implemented, but it was tagged with related-to-v1. Is this something being considered for v2, or is it possible to consider for v1 or v2?

This was already implemented in #87, as to why it's never made it into the main code your guess is as good as mine.

Forgive me if I'm misunderstanding OP

[lazyboy0172]

yes, sorry I believe misunderstanding. The OP would be requesting a config parameter to set how quickly the light/temp goes from max to min.

essentially by default, it goes from max to min back to max from sunset to sunrise.
e.g. if sunset is 7pm and sunrise is 7am, and max/min is 100%/1%, then what will happen is:
6:59pm - light is 100%
7:01pm - light is ~99%
~
12:59am - light is ~2%
1:00am - light is 1%
1:01am - light is ~2%
~
6:59am - light is ~99%
7:00am - light is 100%

if the user wants 'night' to be 1%, it's only like that for 1 minute in the middle of the night. If they set the sleep brightness to 1% and use automations to trigger that at say 10pm, then that means:
6:59pm - light is 100%
7:01pm - light is ~99%
~
9:59pm - light is ~51%
10:00pm - light is 1%

because the light is still 'ramping down' as over the course of the full night, but basically just overriden at 10pm via automation to jump to 1%. This request would be to set the 'ramp rate' via parameter. So, for example, if the user set that ramp to 03:00:00 then we'd see:
6:59pm - light is 100%
7:01pm - light is ~99%
~
8:30pm - light is ~50%
~
9:59pm - light is ~2%
10:00pm - light is 1%

so this time we saw a linear drop from 7pm at sunset for 3 hours until it got down to the minimum value. It would then hold at that minimum value until 03:00:00 pre sunrise, where it would start to ramp up:
4:00am - light is 1%
4:01am - light is ~2%
~
5:30am - light is ~50%
~
6:59am - light is ~99%
7:00am - light is 100%

the reason for the request is that we requestors enjoy the dimming function and getting our minds ready for bed, but recognize that we get ready for bed much earlier than the bulbs would actually hit their 'night' values. and implementing sleep mode just makes an immediate jump from whatever % the light is currently to that sleep %, which can be a significant drop.

Please let me know if I misunderstand the functionality though. It's been a year or so since I last used this daily. I've kept it installed and check release notes every time there is an update but haven't turned it back on since I hadn't seen anything like this in the notes. But I have noticed a lot of development lately so I thought I'd check in on my old request.

This is exactly what #87 does
