I'm not sure to whom this request should be addressed. @Hubitat_Staff
I have an Aeotec Siren on one hub, called "Devices" (where I have all of my devices).
On another hub, I have all of my apps, called "Apps" (including HSM, alarms, etc.). Devices are brought from one hub to another via Hub Mesh, no problem.
However, on the Aeotec Siren device, the "Siren Sound" (which is a Preferences) can only be changed on the "Devices" hub, not the "Apps" hub.
Can the built in driver be changed so that the siren sound be modified on hub mesh hubs?
They shouldn't be. Can you provide a screenshot of an example? You can change some device information, including the Device Label and Room, on the linked hub.
