Oh you’te referring to the presets.json shown above. I see that being a good idea, however, that doesnt solve the multi switch input problem, right?
Why not?
I installed everything as per your instructions. They all work on its own. However, when i pressed 2 buttons at the same time, e.g. when I’m braking while the turn signal is on, it cancels the first button pushed, then starts the preset for the 2nd button pushed. Unless I’m not understanding this right, i will have to pick between turning left, or pressing my brakes. Am i wrong?
Every combination of switch inputs results in a unique value. Each of those values needs a preset assigned to it. If there are 4 buttons, there would be 16 different combinations/presets to configure.
Not necessarily if those presets don’t interfere with others.
That’s why custom API in each of them.
Using this usermod to build a custom switch button combination for Hazard mode i make it for myself long time ago using esp32

Hi johnycokeche07 This looks like something ive been after. How are the inputs sorted. Left and Right for input 1 and 2? and what is the 3rd input, DRL or park light? Very curious. Cheers
Fairly new to wled and very new to the forum. Right now a lot of this is completely over my head, but I have a similar simple goal.
I have and electric skateboard that currently has brakelights. They work as running lights and have a brake light function when the brake is applied on the remote.
I could set a strip default to red so the running lights would turn on when the board is turned on. Then I would just have to splice into the break wire and have that trigger a preset some how? Flashing etc. Then when off the brake, just go back to running lights.
Since this is a simpler task could this be achieved with just “button pushes” triggered but the existing brake lights?
Sure. Only need a couple of presets.
hi , im tryng to implement your solution but when i edit the API to modify the LED count for the segments it appears to be very glitchy/unstable. for instance i will edit the length for “Brake On” get it to work than edit the length for “Hazard On” but as soon as i save it will break “Brake On” it will no longer turn on. i have tried doing it in wled 14.1,14.0, 13.3 and have tried editng LED length 1 at a time also all at once. im using a esp32, with 2 LED strips on different gpio pins. i dont know whats wrong
Make sure when you make segment changes, you only check the segments you want to modify.
Then when you save the changes to a preset, click “overwrite State” and “Checked Segments only”.
That will make sure your changes don’t overwrite anything else that’s active.
i tried modifying the segment LED start/stop for “brake on” under the API of preset [99] while only haivng the “Brake On” segment checked, and it worked, but as soon as i work on another modying another segment length , the previous one become unfunctional. Does the API of preset [99] have any special command lines or can i just do these presets/segments from scratch?
edit; still doesnt appear to work , this is my steps i use: i load the Preset.json>reboot>assign preset 99 as boot>reboot>then i check all segments and edit segment 99 API to edit the LED start/stop>reboot . now i go test out each preset labeled “On” but only Hazards works . Left: 8 LEDs, Right: 13 LEDs, tottal LEDs 21
has anybody gottten this to work? as soon as i upload the json file, none of the pre-configured presets work properly
Did you end up getting it to work?
