Hey James,
It is possible to run both your existing alarm controller and SmartThings Smart Home Monitor via my solution, but we don’t recommend it. The simple way to do this is with a “relay module” that’s compatible with your alarm panel. You’ll have to do some research to determine if your alarm manufacturer has such a device. Basically a relay module is a way for your existing alarm controller to also switch on/off an external device, in this case that would be the Konnected SmartThings integration.
The problem with this though, is that your existing alarm panel still controls all the logic of arming/disarming the system internally, and SmartThings now only monitors the status of the doors/windows/motion-sensors. It creates a duplicity in control that can be confusing and suboptimal, because it limits what you can do with SmartThings, and you still have to type in a code on your alarm panel every time you come and go.
If the only thing you’re concerned about is backup power and Wifi, there are other solutions for that. For backup power, you can tap into the AUX Power Out of your alarm panel to power the Konnected device, and in case of a power failure it’ll piggyback on your alarm system’s backup battery. You’ll also need to get a UPS device for your WiFi router and/or modem as well, so those will remain up during a power outage. For backup internet, you can invest in a Multi-WAN capable router if your ISP often has outages and subscribe to a cheap backup ISP. We’re also looking into ways to configure multiple WiFi access points in the Konnected device in a future enhancement.
I hope this helps! Please also see the latest release announcement for this project and our new online store where we’ve begun selling plug-and-play kits bundled with one-on-one support to get you up and running quickly and easily.
