If you have a different version of a device in the database, before adding another entry to the database, check that the association group configuration, parameters, and channels are the same. If they are, then it is only needed to update the device IDs of the existing device.
Looks like it’s our case - according to the manual, nothing of listed above has changed compared to the existing v.1.0 database entry. So what’s the need to create and fill in a new entry with id 1164?
It’s hard to be 100% sure in it, because the device came only with a quick start guide, and manuals on the web don’t state firmware version. But all manuals I’ve seen correspond to the characteristics in the database entry 990. I was going to check popp official website, but it’s down for maintenance.
Check the command classes in your xml against the old entry in the database, especially those which have channels available.
Check all the configuration parameters in the xml from your device against the old device in the database.
Check association groups in your xml from your device against the old device in the database.
If everything looks the same, we can remove the new database entry and add your device to the existing database entry.
