OK, those specific sensors use a proprietary frequency at 319 .5. This is neither Z wave nor zigbee ( which are the two protocols that smartthings supports)
Consequently, there’s no way to make those particular sensors visible to SmartThings.
Many security systems use proprietary protocols for security reasons. They want to limit the ability of outside devices to get into their network.
Frontpoint does have an optional zwave module which they used to add some lighting control, but I don’t think you can add a secondary controller, which is what you would need to do for enough integration to see the smart things controlled Z wave sensors. And you still wouldn’t be able to see smartthings controlled zigbee sensors.
You can try a forum search, but I haven’t actually heard of anyone being able to combine a frontpoint system with a SmartThings system.
Sorry, I know that’s not what you wanted to hear.
I’d suggest getting in touch with frontpoint support and asking them if you can add a secondary Z wave controller to their system.
I know this is an old discussion, but for the benefit of people searching: FrontPoint uses alarm.com for its back-end, and it is minimally possible to integrate that with SmartThings. This doesn’t get you individual sensor data but it does at least let you arm the system (and disarm it, but that’s not necessarily advisable).
