Thank you for your offer, but I must decline. I have spent many days troubleshooting this. I am a retired IT professional, and I understand how to do this. I have run the speaker on different versions of ESP Luxe as well squeezezelite. It has always been problematic. I have tried every step in this thread, performed multiple resets, and it just will not work on this version. It works on older versions, as well as just about every version of squeezelite, although squeezelite periodically locks up and needs to be rebooted. I have spent enough time on this and I donāt care to continue to troubleshoot this particular problem any further. If the software on the website is updated to a new version I will try again sometime but for now I am moving on.
Too bad! Here (and in many places) it works well: HA/Assist, Radio Browser, Music Assistant, etc.
If you change your mindā¦
Best regards.

Ok, I looked at this again. Here is the offending entry from the logs, it starts rebooting right after this. But it works fine with other versions:

Thank you for your assistance
Using an older esphome 2025.2.2 luxe_microWWW.bin file from New (=> esphome 2025.2.2) Ā· RASPIAUDIO/esphomeLuxe@32d4a87 Ā· GitHub works. Muse Luxe is online and working. There is definitely something about the newest version that does not work with my luxe.
Hi Raymond!
What we see is that the size of the binary you are trying to load is 8MB while your flash is 4MBā¦
This cannot work! 
Can you tell me again which method you are using for loading?
Thank you!
LR
Primarily from http://raspiaudio.github.io/. I also tried installing luxe_microWW.bin with ESPHome from GitHub - RASPIAUDIO/esphomeLuxe.
I made a little correction that should solve your problem.
Please, keep me informed.
LR
Ok, I may not be able to test it for a couple of days but I will let you know after I try it.
@sbar I installed the new version today. Seems to be working fine. Thank you!
