The problem

Hi,

I have an SMLIGHT SLZB-06M (Zigbee Coordinator Mode, Core Firmware = v2.6.8.dev16, Zigbee Firmware = 20241127) connected to a HomeAssistant Green using ZHA.

Both the SLZB-06M and HomeAssistant devices are behind a firewall which blocks all outbound internet access, unless specifically allowed. I have generally allowed DNS and NTP.

After a few minutes the SMLIGHT integration shows "Failed setup, will retry: Connection failed". When in this state, I can access the SLZB-06M via a web-browser...so it's not offline.

All other integrations I'm using are working correctly...it's only the SMLIGHT integration that is the a failed state.

If I update the firewall to allow access to 45.83.192.98 from the SLZB-06M...the integration is still broken.
If I update the firewall to allow access to 45.83.192.98 from the HomeAssistant Green...the integration starts working again.

This is 100% reproducible.

Ideally the integration should not lose connection to the SLZB-06M when HA doesn't have access to the IP address shown above, but if the integration requires internet access to function it should be declared as such.

If you need further info, please let me know.

Thanks.

Hi,
The SMLIGHT integration only makes local api calls directly to the SLZB device. We do however require internet access to download the firmware update manifests that provide data for the update entities, which come from the below server.

Server:		127.0.0.53
Address:	127.0.0.53#53

Non-authoritative answer:
Name:	smlight.tech
Address: 45.83.192.98

Probably this shouldn't block the startup of the integration, however I have never tested in a firewalled environment. I will look into why this is happening. However if you want updates to work from within HA, then you need to enable this address.

Great...I appreciate you taking a look.

Yes, I agree the lack of access to the update server shouldn't block the whole integration from functioning.

Would it be possible to add a System Option that stops the integration trying to download the firmware update manifests so this issue doesn't negatively impact ?

Thanks.

no probably doesnt need an option, if the download fails for any reason it should just disable update entities.

ditto on this issue HAOS 12.4. One is set as coordinator, a second is zigbee/bluetooth repeater.
I comment here, as this issue (as above) is only on this second SLZB-06 setup as a repeater.
QUESTION.... which firmware load (should we be using?) to the radio might be causing this connectivity issue.... EG:
1- oem 2.3.6 loaded from the oem website/app oem website/app
2- Radio web page loaded at slzb-06.local ::: WHICH RADIO MODE SHOULD WE BE USING HERE IF ANY?? :::
3- Load the default from the oem and just use HAOS and ESPHome to config everything??
tia for any clarifiactions... both as proper config.... and could these radio configs be the issue with the IP access routings???

Yes...that makes sense. Please let me know when the code has been amended so I can test.

Thanks.
