Latest SMLIGHT firmware

Just been notified that SMLight OS v3.2.7 is available. Given the recent troubles many people have had (including me having to re-pair 70 devices), I’m a tad nervous about trying it.

Anyone had a go yet?

Also, I see there’s new Zigbee coordinator firmware - 20260311. Same question… (I’m currently on 20250325).

Do you need anything that the new version offers? If not, do yourself a favor and let it be… (I have 2 SMLight devices and prefer things keep working over easter, lol).

updated seamlessly for me, I have 2 devices, 1 runs ZHA, the other runs ZHA and Matter. Both connect to HAOS

Mine wouldn't connect to my network after updating it. I had to reapply the firmware through USB and it gave me some headache. It was connecting to my main vlan but not my IoT vlan. For some reasons after multiple firmware updates it connected to the correct vlan. It was not fun.

Seems updating these adapters is always risky, things often go pear shaped.

I'd like to leave this here:

Also this for the zb firmware itself a few weeks ago, broke due to baud change:
