Entity does not have a unique identifier #1836
Description
i am trying to add a new device type THR320 and getting the following error -
This entity ('switch.1002a9XXXX') does not have a unique identifier; therefore, its settings cannot be managed via the user interface. Refer to the documentation for further details.
due to that i cannot use it in the HA.
at the ewelink works fine.
Thanks

Additional details that might help diagnose this:
Correction/clarification: the device is registered as THR320D (has the LCD display, shows temperature/humidity in real time) - not a plain THR320 as the issue title suggests. THR320D (UIID 181, type
th_plug) is listed as supported in DEVICES.md, so this doesn't look like a "missing device support" case.Current behavior: the switch and both sensors (temperature, humidity) work correctly - I can read all states and send on/off commands successfully via Developer Tools → Actions, and the dashboard toggle works too.
The problem is specifically: no
unique_idis generated for any of the three entities (switch.1002a9c3db, sensor.1002a9c3db_t, sensor.1002a9c3db_h). They show the "no unique identifier" warning in the UI and cannot be assigned to a Device or Area.I also have some leftover orphaned/unavailable entities from earlier pairing attempts not linked to any integration - not sure if related, but mentioning in case it's relevant to how the device was first added/re-added.
Happy to attach the diagnostics JSON (Settings → Devices & Services → Sonoff → Download diagnostics) or DEBUG log output if that would help pin down the actual UIID being reported - just let me know exactly what's most useful.
Thanks for maintaining this project!

Any update ?

All entities from the integration have a unique identifier. If an object doesn't have an identifier, it's not from this integration.

You need to figure out where these entities come from.
