Node-red-contrib-wled2 is not working anymore after latest update WLED

Third party integrations Node-RED
1

I do use node-red-contrib-wled2 for controlling a LED-ring with ESPHome.
I do use it to give signals for events.
It worked very nice until latest update of the WLED integration.
After a restart of the WLED device it is working for a little time. After that The ledring is only showing the pattern in bright white but not the color anymore of a pattern until I do a restart of the WLED.
node-red-contrib-wled2 is not maintained anymore.
Is there an other option to control WLED and using patterns in NodeRed?

Thanks

EDIT:
I learned that in the WLED 0.15.3 the API is changed and sometimes the segment is changed from 0 to something else.
I added a function node before the WELD2 node to force to use segment 0:

// kopieer bestaande payload van WLED2 node

msg.payload = msg.payload || {};

// voeg segment 0 toe

msg.payload.seg = [{ id: 0 }];

return msg;

I hope this will work

EDIT 2:
No is not working. I’m not able to select color in HA that choice is not available only effect

I don’t know what to do

I love wled but find it unruly when trying to automate it. I rely heavily on presets mainly because I use different segment configurations.

Thanks for the answer.
How to create presets?
I do have the feeling that the integration itself is buggy.
It differents all the time
Then I can only choose effect, then color and effect, then it shows color and effects, but color is not changig when choosing different color
All within a minute and not changing anything

I do receive an error in NodeRed:

msg : error

name: "HomeAssistantError"

The presets are created through the wled web gui. General color temperature and brightness is handled by adaptive.

Since I rely on the ‘on chip’ presets I created this flow that will find any wled in ha and then back up the config and preset file.

Thanks again. This is highlevel NodeRed for me :smile:

There is no configuration necessary. Just deploy and hit the inject to create the backup. You can set the inject node to fire on a regular basis. The file are stored in media/wled.

I did find a workaround by restarting the WLED device after every action
