Things You Should Know about Smart Smoke Detectors:

Like most smart home appliances, smart smoke detectors are available from a few manufacturers and share almost identical functionalities. Some of the models need to be installed on a ceiling whereas there are some that can be mounted on a wall. Some smart smoke detectors require hardwired installation while there are a few that just needs to be plugged into a power outlet. These smoke detectors are either battery-operated, features wired connection or operate on a Wi-Fi network. Eventually, they all serve the same purpose – alerts you when any smoke is detected in your house.

Here are a few things you should know about these smart smoke detectors:

  • When you are upgrading a hardwired smoke detector, remember to replace all the detectors with the ones that share the same model and the same manufacturer. The very reason that you do hardwiring of your smoke detector is that whenever one detector identifies the danger, the rest of them triggers at the same time to alert you. However, this might not be possible if you install smart smoke detectors of different manufacturers.
  • If you are considering a better and affordable option to replace your smoke detector, here is a perfect piece to look at – Smart Battery. In spite of replacing the entire alarm system, you can replace the cell in your detector with the smart battery. The battery comprises a Wi-Fi radio that connects to your home network and a microphone that listens to the smoke alarm. It also accompanies a smartphone App that provides you notifications on your phone regarding the danger it detects inside your home whenever you are away. In case the alarm goes off, the smart battery works as a standalone detector. The only smart battery available in the market right now is the Roost PP3 Specialty Battery.
  • One more option you would hear in the market if you do not want to replace the smart smoke detector is the smart listeners. With this, you do not need to take out your existing detector. Instead, you have to install an extra piece, i.e. the smart listener that can hear when your alarm is going to be off and alerts you about the same on your phone. However, you cannot consider it the same as Smart Battery as it plugs into a power outlet. Thus, it does not work in case of power failure. The best option for a smart listener is the Leeo Smart Alert Nightlight.

What to look for when buying a Smart Smoke Detector?

Does it detect smoke and Carbon Monoxide (CO)?

Many of the smart smoke detectors offer you with a smoke and CO sensors combined into one so that you can keep an eye on both the dangers whether you are at home or away.

How much are its sensitivity and accuracy?

Well, it is difficult to check the sensitivity and accuracy of a smoke detector. However, you can consider the technology it is built with to be sure.
