WLED integration does not support older firmware

The problem is that after some HA update my wled integration started showing error: Invalid response from API: Unsupported firmware version 0.13.0-b6. Minimum required version is 0.14.0. Please update your WLED device.

the problem is that i can not update wled controller to newer firmware (believe me i tried) because it brick it. It is custom preflashed from aliexpress and that seller specifically says do not update.

So my only way is to somehow downgrade wled integration or maybe there is a trick to bypass that firmware check?

Can you still reach the WLED web interface after the v14 update?

If so, paste a link to the vendor’s device web page and high-resolution photos of the front and back of the controller PCB. It likely just needs a few GPIOs changing in the web interface.

If not, contact the controller vendor and ask for an update.

Same her, funny thing is the api they say I need to have is an older then the one i have installed:

Failed setup, will retry: Invalid response from API: Unsupported firmware version 0.14.0-b27.31. Minimum required version is 0.14.0. Please update your WLED device.

This is the error it produces, I can not and will not upgrade my wleds, for I have a sound reactive version I like. But since the update of HA it fails. I seen a topic somewhere in the forum, I lost this post in which the moderator says “simple change this and it all runs”, but I see no way to get that done.
