yessss thank you so much! I've been at this for almost a month (i'm using text scroll in an artwork) and this video solved all the problems I was running into! I'm new to using the WLED server - has anybody tried transferring the server over to another wifi network if they've taken their matrix someplace?
You're very welcome!
As for transporting WLED: I [think] if you fire it up and it does see it's saved Wi-Fi it'll default to an Access Point (AP) mode. From there you can input the new SSID & Password using the WLED Phone App.
Great. Great!

You really amused yourself with "..That Box!" LMFAO
The 'Blooper' does even come close to what I was like at the time. I stopped recording but was almost in tears! LMAO
Great tutorial!!! Question... how to you call out different segments and/or presets?
Thank you.
A: You can really call individual Segments or Presets, as Presets are made of Segments. What you can do is format the rest_command "Data" that includes everything within a preset. Then send that to WLED.
You can get this (JSON Formatted) data by looking inside one of your saved WLED presets.
you can also add custom text to the beginning and end of the states command. like this.
service: rest_command.wled_text
data:
text: "Out door Temp {{ states(\"sensor.station_temperature\") | round(0) }}°F"
Indeed. Any template that generates characters can be sent. Also, if you spell 'Outdoor' correctly you can save space. LOL
@@3ATIVE Cheeky :)
Saved me lots of time thanks
Wondering How would you set the text colour based on state ?
Cool, Glad it helped. 👍
You can add ( "col": [ [R, G, B] ] ) within the REST commands' "payload". E.G.:
payload: '{ "seg": [{ "col": [ [0, 0, 255] ], "n": "{{text}}" }] }'

I'm so glad you found me, after all this time, Where have you been! LOL
Sorry, I don't know much about Spotify, I don't use it myself...
However, I'm sure there's a Home Assistant integration that'll get the info you need.
From there, it should be a simple case of making a automation to "POST" that to the display, in the way I show here.

@@RandysRandomHobbies Oh, I just got the "POSTed" LOL
This is great. Thanks a lot! Never thought, that I'm able to understand all these things around rest api and changing text. You've made my day. I've got one additional question. How can I mix a fixed text and sensor data in one automation? My goal is to display something like
Pooltemp: 29,3 C
In this case, Pooltemp: and the C is the text and the 29,3 is the value from my self made pooltempsensor.
Great to hear! 👍
In your example, your automation action would be:
action:
- service: rest_command.wled_text
data:
text: "Pooltemp: " + "{{states['YOUR-TEMP-SENSOR'].state}}" + " C"
@@3ATIVE Again, thanks a lot. Will give it a try later today 🙂
@user-qm3bs1hu3p My pleasure. Lemme know if it works the way you wanted, or if you need anything else.
Fantastic instruction! Any ideas on how to display static text for a sign in WLED?
Any text (on one line) won't scroll if it's less than or equal to the number of characters that fit the width - Normal size letters that's 5.
@@3ATIVE Brilliant! Thank you sir, you do great work!
A bit of a tangled web for this neophyte but you detail it well. What happens if you remove power from the setup? Will it remember the last scrolling message and just continue when power is restored? (Like if you had it on a timer, or an alexa plug, and it would come on for a few hours every day)
Yes it will, as the "segment name" (which is where the text goes) is saved within WLED.
However, for WLED to return to that on power-up, you need to set that in config > LED preferences, then scroll down to "Apply preset [xx] at boot".
@@3ATIVE Thank you!
Good video friend and very interesting. Friend, I can translate it into Spanish and share it with my friends and followers. Thank you for your attention. Greetings from Colombia, Latin America.
Thank you, @donpera3654! I appreciate your support. Sorry, I can't allow that, it would take away from my views.
However, give me a day or two and I'll translate the video for you.
@@3ATIVE Of course. What happens is that the tutorials now become more interesting with audio or subtitles in the largest RUclips community than the Hispanic community, then the Portuguese one follows, Brazil, then English, but the largest audience is Hispanic, friend, thanks.
Awesome video, helped me alot . is there anyway to just display the time like 21:08 ? I can only get te standard version when u dont have a preset (Yup i am a noob :p )
Thank you, glad you liked it.
Sure, anything you can send to the panel it will display. For the Time, you can simply make an automation, triggered every minute, to send to the panel.
Loving this mate! Just wondering how hard much harder will it be to have clock and temperature displayed. And maybe can't then be switched to get when needed?
Thank you.
I can't see it being too difficult - As I show you can send text, so sending it Time and or Temperature at will is no different. Bear in mind that you only have a 5 character width, anything longer will scroll.
@@3ATIVE Hello, thank you very much for the tutorial, it is incredible, I have managed to set up my own Wled panel and I can send text to it from home assistant, what I can't do is show the time and temperature from home assistant, how do I have to do it, I'm lost with that ? thank you for your magnificent work
@@josesanchez-ot8kp You can send it anything. The key is make a Custom Sensor for the data, then run an automation to send to the RESTFul command.

@@josesanchez-ot8kp Noice 🎁
Hi, great video, the only thing I was able to use to get up and running. Really appreciate it! I have a question and I really hope you can help. I have 2 8x32 and I’ve set them up stacked and it’s running as a 16x32. Now I can create segments and have the top do whatever and the bottom, for example, show the time. In home assistant, how do I direct it to send the info to either ID 1 or ID 2 (segment 1 or 2). So I can have text alerts sent to the top and have the static time on the bottom. Sorry if I don’t make total sense, hope you understand though what I’m getting at. At 12:20 you sorta say other segments.
Thanks for the feedback.
No that makes perfect sense... It'll be the one of the topics I cover in my next tutorial - Which I'm working at atm. TLDR for a YT comment, I hope you can wait. 🙏
Absolutely, don’t mind waiting at all. Truly appreciate your reply and videos. The slow simple explanation, the text at the bottom so we can pause and copy it. (Well I do that anyhow lol) But seriously, it’s all very helpful! Thanks!
@@stephanel273 Cool. I try and make tutorials in a manner I'd like to watch them. So, it's comments like yours that make it all worth-while. 😍
Are you using the additional DC V input? Or do you power the matrix via the ESP32 5V using the 3 wire JST? Thank you
No additional PSU. The Matrix is powered from the 5v Pin on the ESP Module, which in turn is powered by a 2A USB Phone charger.
Fantastic guide. I want to take it a step further with a sensor I created using ChatGPT. I hoped to put the sensor in the automation. It's state is a string. But I just can't get it to work. Any ideas why?
service: rest_command.wled_text
data: {
text: "{{ states('sensor.gptscroll_response').state }}"
}
Thanks, I'm glad you found it helpful.
Try this:
text: '{{states[''sensor.gptscroll_response''].state}}'
in the rest command can you tell it to use scrolling text effect. I currently have the default on boot to some other effect and when I send updated text it doesnt change back to scrolling text effect. The text gets updated thanks
Yes, the scrolling text is effect 122.
Really helpfull
But is it possible to split the matrix using wled/home assistant to show different things on the same matrix, like the temperature and thermometer logo next to it!
Thanks.
Sure, each segment can have any number of LEDs in its Width and Height. So, you just make two segments of 8x8, just make sure you set the 2nd to "Start" at 8.
Then, in Home Assistant, send your first data to segment 0, and the other to segment 1.
Oops, Correction:
Each segment should be 16x8, with the 2nd one Starting at 16.
@@3ATIVEThanks very much for the info ❤
There are lots of matrixes out there. How does one determine the parameters, ie. whether it's vertical or horizontal, serpentine or zig-zg, etc? Thanks for the video.
Mainly trial and error. If it helps, I've added the one I used in my Amazon Shop - There's a link in the video description.
@@3ATIVE Thanks much
@@3ATIVE Just by watching your outstanding video again the answer came to me. Here's what ya do.
Start by setting Settings > LED Prefernces > Length to one, which will tell you where first pixel is. As you progressively increase the Length setting it will light up more leds and the path that it takes will reveal whether it's horizontal or vertical, and whether it's zig-zag or serpentine.
@@joepriority A great way to test.... I just futz around until it worked! 🤣🤣🤣🤣
Great video as always! :)
What power supply did you use for this matrix?
Thank you István 👍
For the video/tutorial I was just running off the PC USB port. However, main usage, just a USB Phone charger - My one is just a 2A.
@@3ATIVE I was thinking about the power supply for the LEDs. When setting up the WLED, he recommends a 15A power supply for the 256 LEDs.
@@istvantanczos5294 That may be true for strings outside. I run my matrix panel limited to 800mA and as you saw very low brightness on the sliders.
- And it's still too bright! LOL
@@3ATIVE how you limit to 800mA? it's somewhere in setting?
@@huczas Config>LED Preferences - Near the top you'll find "Maximum Current"
What would the syntax for a service node red? I can get {"text": "The Quick Brown Fox "} going but not {"text" :"{{states['sensor.entryway_thermostat_current_temperature'].state}}"} to pull the state of an entity? Works perfectly in the developer tools
Hi James,
Without seeing your entire node - Try this:
{{states.sensor.entryway_thermostat_current_temperature.state}}
Great video! How many amps power supply do you need for this?
Thank you Justin.
While it's recommended to have a 5V 15A PSU, WLED has a user settable (software) limiter for the current.
For example: The setup you see in this video I'm using a mobile phone charger (2A) and I've set the limiter to 800mA.
- Even that's too bright to go over 10% brightness. 😎
@@3ATIVE Wow that's great thanks for the explanation
What would be the syntax for the payload section of the rest command when sending text to wled with multiple segments?
payload: '{ "seg": [{ "id": 0, "n": "{{text1}}" }, { "id": 1, "n": "{{text2}}" }] }'
Note the use of "id: 0" and "id: 1" - Zero is your first segment. I hope that helps.
@@3ATIVE Thank you sir, yes it does!!
@@MarkPaterson71 Cool. Glad I could help and I hope you find another Texan soon 😉

Hi,
Would you please kindly show us how to program the text with 3-4 different color line effect?
Also, I would like to make the whole matrix with 4-5 different color lines like the 3 colors flag?
Sorry, I'm not sure what you mean by: "3-4 different color line effect"
However, if you use 3-4 panels (all 32x8) then you can assign different colours to each row of text.
I do have a tutorial (coming soon) on how to connect more than one 32x8 panel to WLED. So, #StayTuned for that! 😎
@@3ATIVE
I meant, with 8 horizon lines, I want to make 4 different colors, like 1 color for every 2 lines.
Or we can make the American flag with red white blue.
Thanks!
What version of WLED are you using to have the 2d configuration options??
LOL it's the first thing I showed in the video. Check out the part about installing WLED... The version is shown there.
Nice work, not sure if its obvious or not, but how do i add more devices (matrix) to use this? i.e when you added the rest_command: in config yaml its only using the one device ip.
Unless you do some fancy coding, the easiest way is to add one REST Command per display.
Hi thanks for replying.
So something like this in the config,
rest_command:
wled_right_matrix:
url: 192.168.0.10/json/state
method: POST
payload: “ “
wled_left_matrix:
url: 192.168.0.11/json/state
method: POST
payload: “ “
@@bryantubb5680 Almost, it will have to be a "List". So each one will need a "-" at the beginning:
rest_command:
- wled_right_matrix:
url: 192.168.0.10/json/state
method: POST
payload: “ “
- wled_left_matrix:
url: 192.168.0.11/json/state
method: POST
payload: “ “
fantastic Do you know if a the panel can be turned portrait and have the text go up or down instead of side to side
With other software yes... Sadly, WLED only scrolls Right to Left.
That’s what I figured. But I thought if there was a way you would know. Look forward to your next video

Now don't say no, you've got the know-how, just give it go!
@3ATIVE thank you 😊 🙏 💓
Sorry for the noob question, but is there a way to push the new state further text of the sensor just once or twice ?
Because in my case the state if unchanged is now constantly rolling on the matrix.
Sorry but, I don't understand what "new state further text" is.
However, if you're asking if the text can be updated when the state of an entity changes then yes...
Just make an automation to update the matrix when the entity state changes.
@@3ATIVE Apologies for my bad expression and thank you for the fast reply -> Can you stop the scrooling text after its published its payload/message?
@@MrMacjex after the first action for the template you could do a action wait for one minute then a action stop or a action turn off device.
Can this be applied for 16x16 led pixel panel?
Sure. But, be aware that at only 16 LEDs wide, you will only get about 2 characters.
How to increase speed text ? It's very slowly..now.
And Russian language strings ( Cyrillic)
As part of the "Scrolling Text" Effect, there is a "Speed" control - So you are limited to its Maximum.
As for Cyrillic font / characters that's down to the languages programming in to WLED. Nothing we can do about that - I mean it can't even display some English characters LOL
Should this still work or is it just me doing it wrong? Even changing the name in WLED doesnt scroll
Yep it's still working.
FYI - Text of 5 characters or less won't scroll.
- Maybe that's what you're seeing??
yep, that's the vital bit and the REST was my fault, how many time I've checked i'd got it right.. but as just transposing 2 chars made all the difference.. many thanks yet again :)
@@tezgray Ah yes coding... She's a fickle Bit*h. LOL
@@3ATIVE Oh don't I know it ... and what do i do for a living ?.... yep that's right 🤣🤣🤣
Whats happening when put the brightnes to the max :P

Yes, in Home Assistant you'd just need to connect to the RUclips API and make a Text Sensor to push the value to the Matrix.
