Installing a Roost Smart Battery will be a three-step process: Download the app to your smartphone, name the smoke detector it's going into, and then select your Wi-Fi network and provide its password.
The app passes that information to the battery before you plug it into the smoke detector. This will let you know exactly which battery needs to be replaced, and that's important because most homes have more than one and it can be a pain to determine which one is chirping.
Informing you of impending battery failure is the one thing the Leeo can't do. But Peeters anticipates his lithium-based disposable battery will cost $25 to $35 and last five years when it comes to market in the second quarter of 2015 (that's assuming a successful crowd-funding campaign later this fall).
My home has six smoke detectors, and one $99 Leeo can tell me if any of them are sounding off. Six Roost Smart Batteries would cost between $150 and $210 every five years. That's a lot of cash just to avoid being awakened by a chirping smoke detector every couple of years.
What do you think? Is a smart battery better than a smart nightlight? Share your insight with us in the comments section, below.
