HA Yellow EmberZNet zigbee 7.4.4.1 firmware update keeps failing

Installation
1

For some time I cannot control my Ikea lightbulbs anymore. I suspect that this is related to a Zigbee driver problem.

I’m running HA Core 2025.4.3 and OS 15.1 on my HA Yellow. All other update are flawless but EmberZNet zigbee 7.4.4.1 keeps failing.

Can I apply the update in some other way? I hope that will fix the zigbee issues.

Thanks

I am also having this problem—see related issue on GitHub: Update to 7.4.4.1 - Failed to flash firmware · Issue #111 · NabuCasa/silabs-firmware-builder · GitHub

Hi Jeff, the logs showed that another device alread used the port. I fixed it by uninstall Zigbee Home Automation. Once I did that, I could install the update. Then I reinstalled ZHA.

Hope it helps.
