Firmware version 0x26540900 for ConBee III

Firmware version 0x26540900 for ConBee III
After 24 hours deConz lost the connection with the stick.
After re-flashing the previous firmware, all was good again.
Said that a stable system is going down after a new firmware.

First the light went off line and after that the power plugs.
After the reboot, the stick did not want to connect anymore.
At that moment I decided to go back to the previous version
deCONZ_ConBeeIII_0x26530900.bin.GCF 11-Jul-2024 09:58
All items connect properly and all was running well.

Please check out the version 0x26550900 (Firmware Changelog) that was released today it has a fix for this, this also hit my setup.

Same for me :slight_smile:

Wait a new version.

Maybe I will try next weekend.
I was no fun, to notice that the entire system was failing just before going to bed.
That the system is headless and located on a not really accessible location.
I took me some time to flash the old firmware. (which worked as a charm)
Maybe I just stay on the firmware, it is stable, not to many issues.
We will see, no hurry.

I had the same issue and also had to revert to older firmware. Updating to 0x26550900 that @manup suggested has been positive. Been running without issue for a few days now.

Hi, I developed this firmware, and there was a UART-TX buffer pileup at firmware0x26540900 that didn’t occur in my test setups—but users like you have experienced it.

To address this, version 0x26550900 introduces a new request-handling flow and a watchdog that detects such lockup conditions and restarts the ConBee if necessary.

The root cause of the issue relates to the migration to a new SDK, as Silicon Labs now maintains two SDKs, with the older one likely to be deprecated in the near future.

Which version of deconz are you on?

I am running deConz 2.28.1 (Last Stable)

Like me. Maybe we have to be in 2.29…

No, 2.28.1 is the latest stable release.
I am not going to work with beta versions.
The system has to be stable.
To many heating valves and other things are running on this system.
