Below you can find and introduction video that gives you a good idea of what you can do with multiple interfaces.
How many interfaces can I create?
You can have up to three different interfaces in one project
How many interfaces can access the Neets Controller at the same time?
Up to five different units can access the system at one time
Is it possible to mix between interfaces showing the same page?
Yes, you can mix as you prefer. As an example, you could have two touch displays showing interface 1 and two displays showing interface 2 and one display showing interface 3. Maximum number of total units are still five.
Can I use these multiple graphical interfaces for a three-room installation with door switches?
If the system status are based on I/O inputs, then no. (Advanced scripting is required)
If you only have two different states for the rooms, e.g. all rooms combined into one and all seperated, then yes.
Is there separate Master Page for each interface?
No, the Master Page stays the same and protrudes through all the interfaces
Attached here you can find some test projects based on a SieRRA II and Tango controller. In these you can find simplified examples on how multiple interfaces can be implemented:
