Control4
Integra integrates with Control4 using the ETHM-1 Plus module using a free driver.  The driver is currently in testing at Control4 HQ in Utah, and will appear in Composer soon. We can freely issue the driver in the meantime if dealers want to use it before Control4 finish testing, there may be the odd bug as testing has not finished, but we will be reactive to dealer feedback.  


Crestron
This module is in development/testing at the moment and will use the ETHM-1 Plus module also.


RTI
Integra integrates with RTI using the ETHM-1 Plus module and a third party driver available via this website.  http://www.myrti.de/drivers.php.
As previously mentioned, I have negotiated a discount for all UK RTI/Satel installers using the discount code.


KNX
Integra has a direct connection to the KNX bus using this module: http://www.satel.pl/en/produktid/932.


GPRS-A
There are two good overview videos here: https://vimeo.com/260041018/ and https://vimeo.com/263825569.
This module basically creates a virtual monitoring service for an older alarm.  By wiring the phone dialer on the old alarm PCB into the GPRS-A and adding a sim card with data – you get app control of the alarm with push notifications using GX Control.
