Anything in the logs that might be useful for us?

There are a couple of errors in the logs:

Error fetching wled data: Invalid response from API: (503, {'error': 3})

I've also started getting these errors crop up - possibly only since updating WLED to 0.15.0 build 2412100

Was on 0.14.x without issue, now have seen this at least once since updating to WLED 0.15.0 (build 2412100)

Also using esp8266 for all my WLED controllers.

On version 15 I have the same errors. Previous versions did not show this error. When using scenes and added as device the problem occurs but when using entitys it is not.

[mrLeonTheMaster]

I don't know if this matters, but i have 3 segments configured in WLED.

[KimpiegamesYT1]

Having the same issue here, Nodered often reports: HomeAssistantError: Invalid response from WLED API

[syrisara]

I don't know if this matters, but i have 3 segments configured in WLED.

Coincidence? Me to!

[Nunak]

I have same issue after upgrade to 0.15 and I am not ussing segments (I have only one) and I am on esp8266

[daernsinstantfortress]

I don't know if this matters, but i have 3 segments configured in WLED.

I have two WLED devices controlled by a HA scene. Both failed to come on this evening as they should reporting "Invalid response from WLED API". One has three segments defined, the other just a single segment, so I don't think that this problem is limited to just those running with multiple segments.

Edit: Downgraded back to 0.14.3 and the problem has disappeared and everything working well again. These are xmas lights so will be back in the box this week. I guess I'll see if it's fixed next year :)

[marleyjaffe]

Also experiencing this issue. Error while executing automation automation.turn_lights_off: Invalid response from WLED API

[RandomGHUser]

Experiencing this same issue as well. Sometimes (but not every time) my WLED automations will fail with the message.

[imaerials]

Same here , 0.15 version

[OptimusGREEN]

Yup, 0.15 broke it gor me, had to downgrade all my lights to 0.14.x to fix it.

[Tommatheussen]

I tried running debug logging to see if anything more useful popped up, it wasn't easy because it just randomly happens (so a lot of logging happens before it triggers). Attached the log file, nothing meaningful (in my eyes), running lots of different WLED devices (both ESP8266 and ESP32). Seems to have started as soon as I upgraded my devices to 0.15

[KentuckyMC]

Same issue on my side. Everything worked rock solid, no issues there with my automations. Now it seems like some lights are staying on with the invalid response error. Guess best for now is rolling back the update?

[ChrisToxz]

For me the issues are resolved in 0.15 after I erased the flash of my ESP and reflashed WLED 0.15, so not just a regular reflash.

I used esptool CLI to do this.
Command: python -m esptool --port COMx erase_flash
First I made a backup of my config of course.
After that I flashed 0.15 again, restored my back up and all the unreliability issues were resolved. (At least for now, 6+ hours)

[Tekwyzard]

I'm having the same issue, to the extent that I've even tried running WLED 0.16.0-alpha on one of my instances an esp-01, thinking that maybe the WLED developers are aware and fixed it in a nightly version, and it's still throwing the same error occasionally, along with my other various esps running WLED 0.15.0. The only stable one is running 0.14.4. I'm on Home Assistant 2024.12.5, and I'm not updating to the latest version of HA until they get their act together to fix some of the many issues that they rushed it out with, so I don't know if HA 2025.1.x has fixed the WLED issue, or not.

I've tried that, a few times actually, but the issue remains. For me at least, it seems to be related to HA 2024.12.x as I don't recollect having the same issue with the prior version I ran (2024.10.4).

[wjb178]

Same occasional error for me.
Home Assistant 2025.1.2
WLED
Firmware: 0.15.0
Hardware: esp8266

I only have one esp32. I haven't seen errors on it.

[mrLeonTheMaster]

I recently found out, that sometimes when I am controlling the lights from the wled web interface, a red bar shows up on the bottom with the text Invalid response from API, so i think, that this is not a home assistant issue, but a wled issue. @Aircoookie

[swampdogmash]

Seeing similar issues too. I have an automation that turns on 2 lights in my back garden and also a wled driven set of leds under my steps. Occasionally the script fails and the ights remain on with this same error shown in the trace preventing the second half of the scruot from running. I am also running 0.15.0. I also occasionally get the red bar at the bottom of the wled gui saying connection to eled failed when it never even dropped a ping. I strongly suspect wled rather than home assistant also...

[FGOD1983]

I am having the same issue with my ledstrip in yard. Sometimes when the automation triggered by a motion sensor is turning the ledstrip on, it fails to turn it on with the mentioned Invalid response from WLED API error. When I then manually try to turn it on, there is no issue at all.

But as @mrLeonTheMaster mentions, I also have been seeing a similar thing on the web interface, so could be more related to WLED itself then it is about issues with the integration/HA.

[KentuckyMC]

Is there already something like a issue on the side of WLED itself? I haven't found something? Otherwise we can refer it here maybe?

[imaerials]

Im testing with 0.14.4 seems to be more stable than 0.15 , at least with the no response issue.

[FGOD1983]

I have reverted the particular device I noticed these issues on to 0.14.4 too and created an issue on the WLED git about this too: wled-dev/WLED#4546

as for the device I have this issues on, it is a ESP8266

[FGOD1983]

from the looks of it the 0.16 nightly build fixes this issue and it is caused as suspected by the esp8266 module not being fast enough to handle more requests from HA in time. You can read more about it in the mentioned issue I created on the WLED git

[wjb178]

That makes sense.
I haven't seen the error in a few days since I tried a few changes. Still on 0.15.0

Changes:

1. I disabled wifi sleep on esp8266 wled devices.
   Visit device then Config > WiFi setup > Disable Wifi sleep checkbox
   (my esp32 devices were set for Disable Wifi sleep by default)

2. Home Assistant 2025.1.2 > I updated to 2025.2.2

3. In automations where I was turning on wled I was using the light turn on action followed by the select preset action. I
   found only using the select preset action turns on the light with the preset

I think point 3 makes the most sense here. Never thought about this, but I was doing the same the other way around. Set preset, then turn on the ledstrip. But if the preset is saved including the on state, it indeed also turns it on. So having a turn on right after that could indeed cause issues. If the saved state with the preset was set to off, it probably has no issues with this

[wjb178]

Could be. But I was getting most of my errors when an automation that simply turned off the wled after it had been on for a long time. So I was thinking the wifi sleep might be a culprit too.

[stephanedupont]

All my WLED strips have Wifi sleep disabled, and yet I was encountering the problem with 0.15.

[wjb178]

That's interesting. I did forget about another thing I did. On each wled device webpage I had flashed 0.14.4
About a day later on each wled device webpage I flashed 0.15 again
