Both the Roost battery and the Leeo
smart alerter offer this function.
Not exact matches
We tested two of these
alerters, the Leeo
Smart Alert ($ 50 currently) and the Kidde RemoteLync Monitor ($ 100 currently), and the Leeo was the clear winner, hearing every test alarm and real alarm we triggered and alerting us considerably faster than the Kidde.
(Tip: For any
smart smoke alarm or
alerter, turn on the Alert setting for the app in your phone so that any notification requires a dismissal from you, making sure that you see it.)
