How do I use segments?

Preset. The list does not open in basicUI. In the settings WLED Interface I added preset16 after creating the files of things and items. Maybe this is the reason?
Thanks!

matt1 · November 19, 2020, 10:09am

What version openhab?
What are you using to send the commands?
Jar or is it the merged binding?

Olymp · November 19, 2020, 10:34am

openHAB 3.0.0
Build #2017

BasicUI

Binding

How do I use segments?

matt1 · November 19, 2020, 10:55am

See readme here

github.com

openhab/openhab-addons/blob/main/bundles/org.openhab.binding.wled/README.md

# WLED Binding

This binding allows you to auto discover and use LED strings based on the WLED project:
<https://github.com/Aircoookie/WLED>

## Supported Things

| Thing Type ID | Description |
|-|-|
| `wled` | Use this for RGB and RGBW strings. |

## Discovery

The auto discovery will find your WLED if your network supports mDNS and the UDP port 5353 is not blocked by a fire wall.
Before discovering any WLED devices, you may wish to name them by providing a 'Server description' in the WLED web page, CONFIG>User Interface> setup page.
openHAB will then discover and auto name your WLED to the name provided as the 'Server description'.
If it fails to find your WLED, you can still manually add a `wled` thing by using the UI or textual methods.
For multiple segments, the binding will only auto find the first segment.
For additional segments, you can add them manually and set the `segmentIndex` config to the correct number shown in the WLED control web page.

It needs to be a build made in the last 10 days.

Also check your sitemap against the example in the readme.

Olymp · November 19, 2020, 1:50pm

Yes! This is a different file than what I was looking at.

There are differences, tomorrow I’ll try and report back.
Thanks!

matt1 · November 19, 2020, 9:07pm

Some changes were made to get the binding merged and that newer readme will go live when V3 stable is released in a months time.

Olymp · November 20, 2020, 7:36am

I couldn’t figure out how to manage segments
Did I understand correctly that you need to create as many things as there are segments?

Thing wled:wled:stairs_seg0 "seg-01" @ "box" [address="http://192.168.215.29:80", segmentIndex=0]
Thing wled:wled:stairs_seg1 "seg-02" @ "box" [address="http://192.168.215.29:80", segmentIndex=1]
Thing wled:wled:stairs_seg2 "seg-03" @ "box" [address="http://192.168.215.29:80", segmentIndex=2]
Thing wled:wled:stairs_seg3 "seg-04" @ "box" [address="http://192.168.215.29:80", segmentIndex=3]
Thing wled:wled:stairs_seg4 "seg-05" @ "box" [address="http://192.168.215.29:80", segmentIndex=4]

I split into segments in the WLED interface and saved in slot 16.
In BASICUI, no matter what segment I switch, all the segments are switched.
Unfortunately I don’t understand how it works

matt1 · November 21, 2020, 9:21am

Yes, as each segment can have a different FX loaded you need a new set of controls for each. Some tips are:

Don’t create segments that overlap, make sure each start and end LED is not overlapping or you get conflicts and it does not work very well.
Some of the controls do nothing or may cause issues as the firmware does not support segments and cycling through FX for example, so those controls should not be linked.
Expect some bugs in the firmware for segments and also expect some big changes in the next firmware of WLED for segments as I believe they are doing a lot of work in that area. I had it working pretty well here, but then after a few minutes of nothing being touched I got glitches and it changing randomly to a new colour.
You need to use the most up to date firmware.
I am not tech support, you need to work it out by playing around with it.

Olymp · November 21, 2020, 10:17am

Thanks! I’ll try again later!

yfaway · November 30, 2020, 1:32am

@matt1, I just tried the binding and it works very well. Thank you!

I do notice one small issue: the list of FX is not sorted alphabetically; it seems random now, making it hard to search by name.

matt1 · November 30, 2020, 1:51am

Thanks for the feedback. If anyone trys the new 0.11 firmware that was released a few hours ago can they post if it works with the binding without issues? It has a long list of changes mostly to do with presets and segments.

Simon_Thorsted · December 9, 2020, 10:08pm

do you have a link to find out more ? about this music led looks great

aditya_Sharma · December 10, 2020, 2:46am

Here is the link.
Please note that it works with esp32 only due to adc limitations on esp8266.
And its quite awesome

Fiftiz · December 15, 2020, 9:31pm

Hello, I am on openhab 2.5.11 , I installed the 2.5.9 wleb binding… all work but … often I have this message :

2020-12-15 22:24:48.797 [hingStatusInfoChangedEvent] - ‘wled:wled:0d995e18’ changed from ONLINE to OFFLINE (COMMUNICATION_ERROR): TimeoutException: WLED was not reachable on your network

After 10 secondes it’s online. An idea please ? thank you guys

matt1 · December 15, 2020, 10:00pm

Sounds like the wifi connection is not stable, the web page for wled probably shows the signal strength to help diagnose it.
Also it is common sadly for some esp8266 boards to have the antenna disconnected and you have to solder bridge a connection to choose between onboard antenna and the socket for external antennas. Google this for pictures and instructions.

Fiftiz · December 16, 2020, 6:03pm

Same problem with two esp82. both are next to the wifi router.

I see an option on WLED : “Disable Wifi sleep” … may be the problem is here…

matt1 · December 16, 2020, 9:35pm

What firmware version? I have never see that happen not even once and mine has been on 24-7 for the last 17 days. I am using 10.2 firmware.

Tim_B · December 17, 2020, 6:38pm

I might have missed it in this discussion, but will the WLED binding become an official binding in OH3?

matt1 · December 17, 2020, 7:23pm

Yes it is already merged so will be installable in the RC1 and newer.

Tim_B · December 18, 2020, 4:50pm

Awesome!
