Hello,
I’m wondering if a usermod contained some simple code to write the to bootPreset every time applyPreset is called, WLED could remember where you left off between power cycles.
Does anyone have a simple example of this?
There is already an autosave usermod. 
unfortunately it does not work with presets.
So the autosave usermod saves when some parameter is changed, effect, speed, brightness, etc, but not when a preset is changed, so it won’t work the way I want?
Can someone make autosave mod for d1 mini in bin file for me? please
Use #bot channel in Discord.
How can I setup the Usermod? It will work after a power off then power on ? Will WLED power on with the last solid color, or with the last preset? If I setup Preset to load at boot (0 = none), does it means that after boot WLED will start with Usermod last selection?
You need to compile for that usermod. See docs in code.
boot preset of 0 means default, which is nothing.
