SMLIGHT SLZB-06 and HA 2024.9.2

Configuration Zigbee
1

I just want to make sure I have this right before I pull the trigger.

My Zigbee coordinator is an SMLIGHT SLZB-06, and I just updated to HA 2024.9.2, which has an integration for the SMLIGHT. But it says I need to update to a newer firmware version for this to work.

Home Assistant gives me this info for the SLZB-06:

Device info
CC2652
by Texas Instruments
Firmware: Z-Stack 20230507

The Web interface of the SLZB-06 shows this:

Device information
Model: SLZB-06
ESP32 Firmware ver: 0.9.9 (Mar 3 2023)
ESP32 version: ESP32-D0WDQ5

(I’m not sure why the version don’t quite match, or what Z-Stack means)

Following the link that HA gives me, I see that 2.3.6 seems to be the stable version, and 2.5.4dev is the latest:

In that list of downloads, I see what I think is the stable version for over-the-air updates:

slzb-06-v2.3.6-ota.bin

Going back to the web interface of the SLZB-06, I see this as the way to update the firmware:

Web interface:

ESP32 Update
Choose file…
ESP32OTA Update

So am I right that the slzb-06-v2.3.6-ota.bin file is the one I want for the update?

Thanks!

I have the version “V2.5.2”.
Installed - https: //slzb-06.local/

I don’t think you can do an OTA update with V0.9.9.

TIP

Firmware 2.x could be flashed only via web-flasher! Coordinator can not be updated from other versions to 2.x version via Over the Air!

I used the web serial flasher from the link you posted but needed to use info from the Flashing FAQ on that page to get the device into boot mode.

The info on what pins to use for this is on another page, at the bottom is a picture of the pin layout.

Mine is connected by ethernet (POE) and I was able to go to V2.5.2 from the V0.9.9 web interface using the slzb-06-v2.5.2-ota.bin file.

You can definitely do in the opposite way to the one provided by manufacturer, and it even will work, but with bugs. For example, if you flashed over the air file from 0.9.9 to 2.x, your zigbee update functionality will not work. That is what i know as i tried the same as you, initially:)

HA doesn’t say what the minimum version is for it to work with 2024.9, but I see two of you have mentioned 2.5.2, so maybe I’ll try that. Thanks for your comments.

You mean it will work as a coordinator, but trying to update other zigbee devices won’t work?

That was a reply to jeffcrum.
Update from 0.9 to 2.x should be done ONCE via Type-C cable. Otherwise some functionalities will be missing

Thanks for this info!

v2.3.6 is the minimum supported version, but some features will only work with the latest v2.5.4.dev firmware.

2024.10 release will support firmware updates within HA as long as you are on any v2.x.x build (v0.9.9 users will still need to update via SMLIGHT web flasher)

Just to close out this topic, I did upgrade to 2.3.6 via a USB cable and it worked fine.

I backed up the zigbee config first, but everything survived the upgrade, and all my devices reappeared in HA just like they should. The notice that I had to upgrade the SLZB-06 has gone away.

Thanks everyone.
