Reolink camera cannot be used anymore after update to 2025.12

[henrykuijpers]

The problem

I was using my Reolink PoE Video Doorbell with Home Assistant. I recently upgraded to 2025.12.

The integration stopped working because of some password issues. Apparently the password that was set was too secure?! There would be issues with encoding (I would assume proper encoding/escaping would fix this), so I changed the password to something less secure.

Now, HA is not complaining about the password anymore, but instead shows:

When I click "Reload", the following message appears in the log file:

I guess there is an assumption that entity IDs have to be migrated? And also, that the (previous?) entity.unique_id would contain _? I guess that [1] is out of range for that list.

Entity IDs (as far as I understand):

@starkillerOG The issue looks a little bit like: #142474

But there the issue is:

new_id = f"{host.unique_id}_{host.api.camera_uid(ch)}_{id_parts[2]}"

Here the issue is:

new_id = f"{host.unique_id}_{entity.unique_id.split('_', 1)[1]}"

@henrykuijpers I am sorry for the inconvinience. Home Assistant has a 6 months deprication period, this means if you update HomeAssistant with more then 6 releases, stuff can break due to missing migrations.
In this case in-between 2024.x and 2025.12 I changed the unique IDs of the Reolink integration, there was migration code in place to smoothly update this in the backend. But since that migration was more then 6 months old, I removed it in some later version. (otherwise I keep pilling up old unused migration code).

This could have been prevented by updating from for instance 2024.1.0 to 2024.6.0 then to 2024.12.0 then to 2025.6 then to 2025.12.

That beeing sad, you only option now is to remove the reolink integration, restart Home Assistant, then setup the Reolink integration again. Unfortunetly that does mean the entity_ids and names may change.
Again appologies for the inconveniance.

[henrykuijpers]

@starkillerOG hm that is very unfortunate... I think I will then completely remove Reolink from my HA and then add the cameras back; I don't have a lot of relevant history to keep or anything.

It's very unfortunate I didn't know about this 6 months thingie.

So the recommendation would be to never skip more than 5 versions, I assume? And that would be the same for any integration, I assume?

[starkillerOG]

Yes indeed that would be my recommendation.
Yes that holds true for any integration.
