Feel free to discuss the 2.9.0 and the 2.9.1 release here!

Note that the 2.9.1 release is a hotfix release to fix the onboarding issue (#31225) introduced in 2.9.0.

Hi,
My zigbee2mqtt broke after the update. All I see on the page is this " Failed to load onboarding data (404)"

Same for me - bare metal on a Beelink mini and also ZBT-2.

Check this #31225 (comment)

Please hint me the right way, my system is running z2m with v1.40.1 on bare metal. (PI4)

With respect to #24198 (comment) , all pre-work is done now

• Should I run update.sh first to version 2.0.0 and then to current version 2.9.x?
• Or may I run update.sh direct from v1.40.1 to current version 2.9.x?

I searched for that info but didn't find a hint. Thank you in advance

[Koenkk]

You can immediately update from v1.40 to any v2 version, including v2.9

My Bosch twinguard smoke detectors now report iaq sensors instead of aqi. Would it be possible to have some kind of documentation which value is okay and which is harmful?
