Roberto,
11008 is “No Authorization” and indicates that a command was sent that the control determined is not authorized.
The most common reason for this is when a disarm command is sent using the Installer PIN, but the system was armed without it. There is a built in safety feature that prevents the Installer PIN from disarming a system that was previously armed using any other method. This includes user PINs, single key arming where no PIN is used, and scheduled arming such as auto arm or rules.
This error can also occur if an installer or user attempts to make a change that their authentication level does not allow. This is less common, as the system typically does not present options that are not permitted. For example, if installer level programming were somehow accessed using a master code and a change was sent to the panel, the panel would reject that change.
If you are connected in the app using the Installer PIN, there are very few cases where changes would be blocked, with the main exception being the disarm scenario mentioned above. If you attempt to edit the system while it is armed, you would instead see a different error code, 11028, which is “Not Allowed while Armed.”
Can you provide a bit more detail on what you are seeing?
Were you authenticated to the panel through the app as an installer or as a user?
Which mobile app were you using, and what version?
Also, can you provide the control firmware version?
Sorry for all the questions, just trying to narrow this down.
Thanks,
Mike
