Integrating More than One System

I have just notified ADT that I am discontinuing my service and still have 3 weeks left on my contract.  In the meantime I have installed a Simpli Safe system.  The Simpli Safe covers the 2 doors, 4 first floor windows, 3 basement windows with basement motion detector and 3 smoke detectors.  I also have Amazon Alexa.  I'd like to add the Konnect system to cover the remaining hard wired windows.  Is there anyway that everything can be integrated?
