WLED Sync Explained

[@vmashchenko]

Thanks! The additional thing that eventually helped me enable sync is "Send notifications on direct change: " underneath the Sync Groups. It must be enabled.

[@handydadtv]

Thanks for the info

[@CKioxide]

Dude I’ve been trying to get sync to work on my 2 ESPs for literally 3 hours and just now realized this. THANK YOU!

[@Random-rt5ec]

Great presentation it pointed me in the right direction. I recently installed a whole bunch of 5 volt led strip lights in the basement playroom and realized it will be easier to control them with multiple WLED controllers. But success won’t be until I program the remote so all my wife has to do is press a button to get the desired effect.

[@handydadtv]

Good idea

[@CosmicNeighbors]

Thank you for taking the time to share this helpful information. Much appreciated!

[@handydadtv]

My pleasure!

[@tankthebear]

Thanks man ... perfect timing ... I have two strings of fairy lights I just setup on an ESP32 just like you have there! I dabbled and found out I THOUGHT how to sync - but it wasn't working quite right. It was more an issue of waiting - didn't seem to kick in right away. Great video I probably will play with using the JSON calls in my home automation later. Subscribed.

[@glennrichardson9514]

Awesome. I couldn't figure out why two strips I had in different rooms were synced. Now I can use them again without frustration! Thank you!

Nice video . I like . Can you test or do you know how to have 2 controllers and each controller to start a Effect when a pir it is connected to controller ? and somehow to cane do (do not consider the motion sensor from 22:00 to 24:00) to use a Effect starting from first controller and continue to second controller (for example to make a chasing effect from first led of first controller and end to the last led of last controller) . It is possible this ?

[@handydadtv]

It’s possible with Home Assistant.

[@gradmihaialexandru3445]

@@handydadtv. I know with Home Assistant We can do more. But, I do not have Home Assistant and it is not poroase to buy for this. I need to do nativ from the wled not other soft/device... Cane you test and see If it is posible?

No. Sorry.

[@trevor305]

Thx for a great video. I currently run two synced controllers and was wondering if the receive can have a certain effect set but have the send controller send color changes?

[@handydadtv]

Possibly. I didn’t play with all the checkboxes.

[@WooderBoyProductions]

So if you press the preset on one wled screen or one controller it will do the same on the other controller? A little confusing.

[@handydadtv]

Yes, the receiver will mirror the colors and effect of the sender. And optionally the segments too.

[@rickybobbyracing9106]

Extremely helpful!

[@handydadtv]

Glad it was helpful 👍🏻

[@GYATEZ]

Thanks for this. I just figured this out yesterday, and so it was fun to follow along and validate my thoughts on how it works. I used the HTTP API so I could create a Siri Shortcut in my HomeKit automation so I could change the presets. I'll have to play around with the JSON more.

[@handydadtv]

Awesome! Glad it was helpful 👍🏻

[@EveronesInvited]

How did you do that?

[@churwck]

Hey Chris, thank you for the clear video. I have got the sync function to work between three boards (with one acting as the master). I was hoping to use a pot wired to the master board to control the brightness of the other esp32 boards. Unfortunately the pot only changes the brightness of the master board, despite the sync function working normally otherwise. Do you have any ideas how to solve this?! Thank you!

[@handydadtv]

No sorry.

[@handydadtv]

Sync isn’t widely used but you might find someone who can answer on Reddit /r/wled.

[@mattu521]

Badass thanks! Can you run directional effects setup as a segments. Tough to wrap my mind around If they would just repeat themselves.

[@handydadtv]

All effects are directional, but they can be easily be reversed. And they all repeat continuously. Not sure if that answers your question.

[@nathanunsworth5495]

I am still having issues with my lights syncing segments - the controller sending the sync signal has 3 segments set up, but the controller receiving the sync only syncs the color of the 2nd segment with the spacing of the 1st segment. No idea. I have segments and bounds checked on both controllers. Any thoughts?

[@handydadtv]

You’ll find more knowledge on Reddit /r/wled than here. Sorry.

[@valwoi]

idk if im doing something wrong but ive setup one esp so send on 8 and the other to receive on 8 but its not working. the slave esp stays on the same effect as before

[@handydadtv]

Keep playing. You’ll figure it out.

[@changchung]

You don't need to slave the wled. You need to connect all of them to the same internet network. After all of them are connected you just press the sync button on each wled.

[@daviddavies2647]

Thank you Thank you. I couldn't work it out but now my sync works.

[@handydadtv]

Glad it was helpful 👍🏻

[@daviddavies2647]

@@handydadtv I was hoping for sync to include led positions in the string. So that two synchronised strings would each light led number 1 at the same time and then stay exactly together. I guess this is asking too much ?

[@handydadtv]

I’m no expert but it seems to only sync the effect and parameters, not continuous synchronization pixel by pixel.

[@charlottewilliamcover3568]

Nice video. Is there a maximum number of node that can be sync ?

[@handydadtv]

I don’t think there’s a limit.

[@charlottewilliamcover3568]

@@handydadtv tks for the quick reply. I have also ask the question into WLED forum.

[@ivangutowski]

just a heads up[, I fo7und my syncing unreliable, I upped the UDP requests resend under sync preferences on the one making the changes, I set that to 5 and everything synced far faster and very reliably.

[@handydadtv]

Good to know. Thanks.

[@scottstevens7569]

Great explanation of 'Sync' which is a very tricky and poorly documented topic of wled. 😄

Thanks so much 😊

[@meguinness1116]

How many esp's can be synced/controlled at once? Ta

[@handydadtv]

I don’t know of any limit.

[@meguinness1116]

@@handydadtv how many leds can the module power when using the USB port without any external power injection Thank you.

[@handydadtv]

@meguinness1116 Voltage drop depends on the length and wattage of your strings. You need to do some math. Rule of thumb is to inject power every 150 pixels with 5 volts and 300 pixels with 12 volts.

[@meguinness1116]

@@handydadtv thank you, I need to run less then 30 probably...so should be ok without injection.

Does this work with audio reactive?

Hey could you give an explanation of master and slave over ethernet connection, i have the DIG QUAD x2 and trying to use them to light up a sound system thankyou!

I have no experience personally. So I suggest asking this question on Reddit /r/wled.

[@deadmusik9969]

@@handydadtv thank you sir!

[@lasse9197]

Is there a way to sync them with no delay? When you want to sync a blinking effect it’s not synchronous:(

[@handydadtv]

When you sync effects, it should sync the speed and intensity attributes with it. So, in theory, they should be in sync initially. But I’m sure it’s possible that they might drift a bit over time. Is that what you’re seeing?

[@bharathwaj2421]

Great Video!! Thanks for detailed explanation

[@jamiestarr1022]

Hello. Great video. I have been watching a lot of WLED videos and am thinking of jumping in. My reluctance is the software. It seems complicated. How difficult is learning curve? Thanks.

[@handydadtv]

If you buy a Dig-Uno or Athom controller that already has WLED installed, there’s no software required at all. Just power it up and connect to WiFi. Really as easy as it gets.

[@jamiestarr1022]

@@handydadtv thanks for the reply. I was referring to how difficult it is to set the lights up in the software. Segments, syncing, stuff like that. Thank you.
