I used to run nest protect. After it got discontinued, I swapped in a set of x-sense smart smoke and CO alarms, and they got put to work pretty quick.

Last week, I was out of state for work when my phone lit up with a push notification that an alarm was sounding. The app showed which unit. Nobody was home, and I was hundreds of miles away, so before that, I'd have just sat there stressing.

But now I have an optional fire dispatch add on. After the alert, I asked my neighbor to check the place. He confirmed something had been smoking in the house, then I just needed to confirm the fire in the app. Not long after, the monitoring side called and sent a truck. I feel lucky that I have this setting rather than just hoping a neighbor noticed.
