Describe the bug

I have a Cytech alarm system connect to HA via the Node-RED companion. One device is configured for the zones, so it contains binary sensors for every zone. In HA settings for each entity I turn off the option for the entity to use the device area, and set each one according to their location. If I make a change to the flow and deploy it, the area setting for the entity is reset to the default. I have used this feature with other integrations, and the setting is retained.

At this point in the log, do recall what action is being taken in NR? The entity should only be removed from HA if you deleted the entity config and deployed.

[zachowj]

Did you remove the custom component, then re-add it?

[sotatech]

I think I did a deploy in NR and a reload of the integration at that point, after setting the custom area on some of the entities in HA as a test. This was to check if the changed setting would survive. I didn't remove anything.

I notice that when I do a reload of the integration, I get a lot of errors about the platform not generating unique IDs:

[sotatech]

I did some more testing and I found that by clearing the area setting for the device, I could then customise the area for each entity and it would be retained through a reload or restart of HA. So it would appear that the integration is assuming that all entites associated with a device will have the same area.
