meross_lan does not generate unique IDs

[Ameglialuna]

I don't know if it's really an issue, maybe it's only my configuration that is wrong. I' m using the last version of the component (but I had this behaviour also with the previous versions) and randomly I find in the log the message that all the devices have not a unique id. Restating Home Assistant the message disappears and then after three or four days returns. It's an issue? And how can i fix it? Thanks in advance, Maurizio.

These are the messages in the log:

Hello @Ameglialuna, It could be that some entity IDs are 'stale' in the entity registry and were not correctly cleaned up from a previous uninstall-reinstall. Or, since all of these messages are related to entities binded to the MSH hub it could be an error in meross_lan in the code for this device (which is treated a bit differently than common switches lights or so) Could you confirm you also have (or don't have) other devices in your setup which are not working through the MSH300? Like I said: switches MSS or lights MSL or any other standalone wifi device

[MaurizioScala]

Hi @krahabb thanks for the answer! In effect I had uninstalled everything and the reinstalled again. I have only the devices present in the log, a MSH300 hub with 5 MTS100 valves, no other devices like plugs or lights.

[krahabb]

Hello @MaurizioScala , I think I've detected a possible issue in the code that manages dynamic addition/removal of hub subdevices: when a subdevice disappears from the hub meross_lan tries to automatically remove that by reloading an updated list of currently available devices. This is where the duplicate IDs might come. I'm slightly modifying that code trying to be more safe on deletions/additions but I'm highly unsure how to test all this. At any rate, could you also confirm/check if one or more messages like 'removing subdevice xxxxxxxx(yyyyyyyy) - configuration will be reloaded in 15 sec' appears in the general HA log slightly before (15 seconds in theory) the offending 'Platform meross_lan does not generate...'.

[Ameglialuna]

Hello, first of all I apologize for the answer as Maurizio Scala, it's always me, @Ameglialuna, I used the wrong Github account :-( Yes I can do all the test you need, I need to wait for the new version, right?

[krahabb]

Not really, the log message should be there anyway.

I'm likely releasing a small patch which would hopefully fix the duplicate IDs if I got it right but seeing the logs we could confirm the issue is there (before publishing the patch)

[Ameglialuna]

Ok, I understood. I wait it happens again and I will check the log.

[Ameglialuna]

Obviously since I started to check the log it has not yet occurred :-(

[Ameglialuna]

Hello @krahabb I saw you released the update. What do you prefer I do, wait to see if there is the message in the log with the 2.6.1 version or I install the new 2.6.2?

[krahabb]

You could install the update anyway. This should prevent the duplicate IDs.

At any rate, the event that was causing that should be signaled by this other warning: "removing subdevice %s(%s) - configuration will be reloaded in 15 sec". This will still happen but the patch should avoid the duplicates.

This event happens when the list of subdevices paired to the hub changes (not very often then....or not at all after you finish setup your devices)

[Ameglialuna]

ok, thanks, I install the new version

[Ameglialuna]

A quick update: no "meross_lan does not generate unique IDs" message in the log until now

[Ameglialuna]

And after 11 days still no message in the log. I think that we can consider the issue solved. Thanks again!
