I’ve got a HyperCube which basically just runs a fork / rebadged copy of WLED. Since the 2024.8 HA update now requires WLED v0.14+ it no longer connects to HA. I’ve failed to find anything online and the support people at Hyperspace say they have no idea when they will release a firmware update.
Just wondering if anyone else is in the same situation or have maybe just flashed regular sound reactive WLED to one of these.
I have the same kind of issue with a custom WLED that fails to upgrade to 0.14 for whatever reason.
I have not yet upgraded to 2024.8 for that reason, but I will likely have to resort to create a custom component out of the 2024.7 version.
Custom components override builtin ones, so the steps are the same as outlined there:
Came here with this EXACT problem and was thrilled to find a relatively simple fix! The link to this guide on how to create a custom component is awesome and easy to follow. My HyperCubes are now working once again using the 2024.7 code through I am running OS 2024.8.
This serves to remind me of not just the greatness of Home Assistant but of the community that uses it as well. Thanks again!
The problem with running a custom old version of the WLED integration is that we then don’t get the benefit that the latest version provides:
Recently got a hypercube, the ethernet jack is wired with 3 wires, if we figure out which is 5v, GND and, data then technically any WLED controller will work.
Do we know if the controller is using a ESP32 or ESP8266, i assume it is a ESP32 do to it having sound reactivity.
Not sure. If I get time over the weekend I’ll crack open the little controller box and have a look inside.
Hey guys,
I’m having the same issue since I’ve upgraded to 2024.8 - my Cube is not connecting anymore…
I’ve rolled back for now but does it mean a firmware update is required from the cube itself ?
If anyone knows how to fix it i’ll be more than happy so I can fully
Yes, we need to either wait for the HyperCube people to release a new firmware which they told me via email that they have no idea when that will be, or flash the cube with normal sound reactive WLED.
Do you have a link of a firmware to work with the latest HA Core ?
And also, if not working - is it possible to flash back to the HyperSpace OS ?
Thanks! 
Not from HyperCube but the latest sound reactive WLED will work (v14+).
They don’t have their version publicly available but I would like to think that they would email it if we asked for it. With that it should be possible to go back to stock Hypercube, which is just a re-badged version of WLED.
They told me they worked with Aircookie to develop the firmware but have no plans on releasing firmware updates. Shame they use open-source software and close it to make a profit and leave the customer hanging, the firmware has not been updated since 2022. They did confirm it is using an ESP32 but did not say which variant.
Are you sure the sound reactive version will flash, what are the GPIO pins and Sound/Microphone Settings? Looks like these things are baked into firmware and without it we would not have a functional controller.
We’d also lose out on the cool effects by going with stock WLED.
Right now, I have it syncing with another WLED controller to turn on and off, which is good enough for my needs at the moment.
Unfortunately I didn’t have time to open up the controller over the weekend. I do have some ESP32’s and microphones spare so I might try setting one of those up as the controller and see how that looks, that way the stock controller can keep the original firmware for now at least.
I was able to open up the controller box and it looks like this :
Any idea where should I plug and what type of cable is needed to flash the ESP32 ?
I would imagine that white connector on the board is probably power and comms. Using a TTL USB convertor it should be possible to power the board up and serial flash it. Would need to work out what pin is what and also the voltage it needs, 3.3 or 5V.
I haven’t had a chance to try it on mine yet.
I finally just did the solution mentioned above!
Which consist to rollback the wled code from the previous HA Core version!
It’s working like a charm and I don’t mind not having the latest WLED 0.14 version
Thanks all!
@Denox , I don’t own one yet. Do you think replacing the entire HyperCube controller with something like a Dig Uno would work? That way, you would have full control of the cube.
I can’t tell how wires are going to the LED strip? Can you confirm that there are 5 wires going to the strip (which would be positive, negative, and data) and then another 2 wires for power injection? It’s hard to tell from the picture.
I did something similar with a cheap cube from Amazon that didn’t use ESP32.
This was the cube: Infinity Dodecahedron Gaming… Amazon.com
The cube had a stereo female input, so I used:
PNGKNYOCN 1/8" Stereo to Bare… Amazon.com
It turned out to be a WS281x, and uses 79 leds.
I don’t see why replacing the controller on the HyperCube wouldn’t work. I’m also assuming that there are no other electronic components inside the cube, just the LED strip?
