WLED as FPP Remote

[Danit2]

I am currently working on creating a user mode for WLED in which WLED functions as an FPP remote.

The FSEQ files can be saved on an SD card in WLED and played back via FPP.

Now I wanted to ask how best to implement this in FPP.

Currently, my user mode provides all relevant data via /api/system/status and is also contained in /json/info.

Unfortunately, not all information is displayed on the MultiSync page.

Could FPP be expanded to display all information?

Which way is better? Via the API or via json/info?

Currently, if WLED does not support MultiSync, the device does not appear on the MultiSync page at all. However, if it is supported, unfortunately only some of the information from json/info is included.

All information is also available via WebSocket. ws://IP/ws

What is the best way to do this?

Here is the data I get from the fpp player via:
http://IP/api/system/status?type=WLED&ip[]=IP

This is pretty cool. MS pulls from multiple endpoints so that may explain why. What exactly is not showing up? Screenshot?
You can also poke around here to see what's missing and how it needs to be formated: https://github.com/FalconChristmas/fpp/blob/master/www/multisync.php

[Danit2]

This is what is currently displayed.

That's what I would expect.
I get this when I do not specify a valid device ID in MultiSync status and FPP falls back to generic and /api/system/status is read.

Currently, when a sequence is played, the status only changes to “playing” but does not show the remaining time and the track being played.

I have read multisync.php, but I don't understand why “advancedView” is not being read, nor the other data.

Here is a direct comparison.

[cybercop23]

Ok, I'm confused. What's the difference between these two? Is it ESP32 vs 8666? Stab-09 seems like it works as expected. Why doesn't the other one work on the same 16.0-alpha version?

[Danit2]

Because one device (Stab-15) reports itself as WLED to the FPP.
typeID = 251

And in the multicast ping packet, the device uses type 0xFB.
So also WLED.

The other device (Stab-09) reports itself as an ESPickelStick device typeID = 195 and in the ping packet 0xC3.

However, since the websocket endpoint of ESPixelStick cannot be reached, logically, it falls back to a generic device and only evaluates /api/system/status.

However, I do not know why the device that reports itself as WLED does not evaluate all the information from /api/system/status or /json/info.

Both are the same ESP32 devices with the same firmware. Only the typeID is different.

Here is the status from the FPP Player of both devices.

[cybercop23]

I see it now. You'll need to also make changes and a PR to FPP to distinguish between plain Wled and the user mod that supports SD. And add status support in getWLEDControllerStatus.

You should also look at the xLights project. We added support to send compressed FSEQ files to ESPixelSticks since there was a 5 min TO. The zipped fseq(s) gets decompressed (on reboot). This way the uploads are very fast.

[Danit2]

@cybercop23

I have now expanded the code.
Compressed sequences can now also be uploaded from xlights.
The sequences are automatically unpacked 10 seconds after no more sequences are uploaded, or each time the program is restarted.

Unfortunately, I don't quite understand the fpp code yet to implement wled correctly.
Currently, it runs as ESPixelStick.
