Save/Restore Current State

Enhancements
1

Here’s another… Would anyone else be interested in being able to Save/Restore the current state? Just a basic, push/pop type of thing. Either as functions, or API-calls for use in macros?

2

I’m sure I’m misunderstanding you here… this sounds exactly like what Presets do. How do you want this to work?

3

I’m trying to do this without using up a slot (or using the only slot, for now, if using segments).

My particular application would be to run macro x when the input is active, then restore what was going on before when it goes inactive. I already have the code setup to handle the input.

4

I suppose I could use &PS=16 and &PL=16 for now.

Actually there is a neat little undocumented feature that could be helpful for you. If you do PS=16&NP the preset will be saved to ram only and not yet persistently to flash memory. This prevents flash wearout if you use the command often :slight_smile:

Nice. then I could do a PL=16?

Update
I found I had to add the NP stuff to 091. :rofl:
I have this for macro 1: &PS=16&NP&TT=0&FX=0&R=255&G=0&B=0
and this for macro 2: &PL=16

Something is stepping on something else as slot 16 ends up being saved as red. I even moved the code to handle the saving up to the top in wled_set.

It’s in the wiki now. Hopefully semi-correctly placed.

What did you change from 19 hrs ago?

Since I’m still on 091, I had to pull the NP code in.

Hi,

I just updated to 0.11 and changed my son’s old sunrise effect (using Nightlight and Color-fade) to the new way of using the Effect “Sunrise” with this Preset settings:

{ “bri”: 128,
“udpn”: { “nn”: true },
“seg”: { “fx”: 104, “sx”: 10, “ix”: 255, “pal”: 35 }}

The “udpn”: { “nn”: true } has the effect that other syncronized WLED instances are not being notified - very usefull :slight_smile:

My only problem with thiis is, that the WLED state BEFORE the sunrise is gone after using this preset.

I would like to save the state, load this preset und one hour later restore the prevvious state.

I tried to call a macro with “PS=99” and then “PL=99” later, but this did not work (as in the then saved “Preset 99” the currect state wasn’t incuded :frowning: - instead “PS=99” was in there)

…any suggestions how to solve this ?

Is there a way to tell WLED via a JSON Object to save the current state ?

@Aircoookie what has been the reason why the "save to memory feature (&NP) was removed in Build 2011152 ? This would be perfect for me as the “save current state”-solution would be triggered once a day and would lead to 365 saves to the flash per year.

Is there any update to this?

I’m looking for a way to have WLED resume the last playlist/preset after power cycles?
