Daily request to add new integration and data format issue

[smartmatic]

Hi,

since some days i get almost everyday a new detected integration like this. Why is this the case?

Second the data format changed for some entities from terrabyte to byte and i am not able to change to terrabyte with the UI.

Please correct it and and keep one format for all entities in Terrabyte

• The 'daily request' comes from a mix of the old way how the NAS was added to HA, and the new 'auto-detect' feature in v2025.11. You should remove the NAS from the devices once (so the old configuration entries are removed), restart HA, then re-add the NAS as offered by the autodetection.
• The 'bytes display' is the raw value (entity name ends with _raw), as reported by the NAS. Raw will be converted to TB in a second entity, as shown in your screenshot. So, this works as intended. Unfortunately, using a separate entity is the way it has to be done in HA, as it is difficult to adjust the unit within the same data collecting entity B -> kB -> Mb -> TB once it has been created on startup. This is a quite popular topic, see e.g. here.

yes i have ipv6 enabled in my network as matter and thread requires it.

So I should possibly add the v6 address to the identifiers. So far it's only the v4 address, which seemed to be sufficient until your report. I wonder what is special in your installation - there are >350 active installations of the integration out there, so the issue should have arisen more often if it was a general one.

After reading again I have 2 more comments:

I have removed the integration and restarted HA. Then added the integration again.

Please do not remove the integration itself through HACS. Just delete all NAS related devices one by one (Einstellungen - Geräte & Dienste - Ugreen NAS - jedes Untergerät mit den 3 Punkten löschen, am Ende das NAS selbst). This will make sure all old device config entries are removed one by one.

If everything fails, you should be able to choose 'Ignorieren' - unless you are getting a new v6 DHCP address for the NAS every day, the daily messages should disappear.

Just delete all NAS related devices one by one (Einstellungen - Geräte & Dienste - Ugreen NAS - jedes Untergerät mit den 3 Punkten löschen, am Ende das NAS selbst).

Thats what i did. I have 10 subdevices included in one main device. I can only delete the main device. The sub devices can just deactivated.

And yes wrong descripton from my side. I just deleted the device and restarted HA. I did not delete the HACS integration. Then i added again the device found by the automatic discovery.

Further to our discussions before, I did some more detailed digging (though I am not THAT experienced with IPv6). At the moment, the NAS device is identified by an auto-discovered IP ('host'):

async def async_step_zeroconf(
        self, discovery_info: ZeroconfServiceInfo
    ) -> config_entries.ConfigFlowResult:
        """Handle zeroconf discovery."""
        _LOGGER.debug("[UGREEN NAS] Discovered device via zeroconf: %s", discovery_info)

        host = discovery_info.host
        port = discovery_info.port or 9999

        # Set unique ID to prevent duplicate entries
        await self.async_set_unique_id(f"ugreen_nas_{host}")

It seems the IPv6 address is changing quite frequently at your end, therefore a new NAS is detected all the time.

For the coming Multi-NAS feature, I am planning anyways to change the unique id from host (IP) to hostname (DNS name) - this is needed for quite a bunch of other things, e.g. entity naming. Please give me some time to implement and test this. Would you be willing to support the works with testing, too?

Hi @Tom-Bom-badil
quick update: So far your latest provided config_flow.py works - No other devices are discovered based on IPv6. Just the NAS based on the local name 👍

[Tom-Bom-badil]

Perfect - thanks the feedback! :)

Also installed your updated config_flow.py and readded the NAS (IPv4).
No new IPv6 devices since two days. Before I saw at least two new IPv6 NAS per day.
Thank you 👍

@Tom-Bom-badil When do you plan to release the updated config_flow.py ?

[Tom-Bom-badil]

I hope to find some time for this (and some more intended fixes, which still need to be done) between Xmas and New Year.

Currently I am extremely busy at work, and there is a good chance I will need to cancel my vacation days between the holidays for getting back to work, too. So, not promising anything at the moment ...
