6 Best Smart Smoke Alarms of 2025

Some modern apartment areas or multi-storey houses always need to ensure safety, from the assembly of electric stoves to connection systems, there are warning devices. One of those smart devices is a smart smoke alarm.

Currently, some of these devices have many upgrades, the most common are sensors that use ionization or photoelectric sensors, which are similar to traditional and smart smoke detectors. In addition, the smart smoke alarms integrate self-test features, making battery monitoring and sensor functionality relevant directly to the phone when troubleshooting. In addition, some of these devices also have a built-in carbon monoxide detector.

They will emit smoke alarms when smart smoke alarms integrate with home automation systems, especially can connect smart home features and sensors, easily recognizing light or heat faster. You can also think of them as Wi-Fi smoke detectors.

Once the alarm is activated, the smart smoke detectors now use Wi-Fi or the same communication technology to connect to the smart home hub and smartphone app. In case the fire alarm is false, you can also use the phone application to turn off the alarm.

In general, installing smart smoke alarms at home will help you feel safe even when you go out but still know everything that is happening. Below is a behomemate list of some smart smoke alarm products and the information you need before you buy the product.

How To Choose The Best Smart Smoke Alarm?

Fire and smoke alarming sensors

Most smoke detectors use one of two types of sensors to detect smoke or fires. Ionization type sensors are good at detecting fast fires, while photoelectric sensors are better at warning of slow fires. Therefore, you should install two types of alarms (if possible) on the premises. Nest Protect is a brand designed to take on both types of fires.

Hardwired and battery powered smart smoke alarms

Alarm systems are hardwired, they are mainly interconnected, when one alarm goes off, all other alarms go off. To work, hard-wired alarms will receive power from the home and use batteries for backup. Most stand-alone detectors run on batteries only, so they require frequent replacement and are unlikely to sound an emergency. However, the installation of standalone smoke detectors should be in important places.

Smart home hub support

The integration of smoke alarms with the home's smart devices is very convenient such as Nest Protect attached to the Nest ecosystem, you can easily choose Alexa, SmartThings and HomeKit available. However, not only this device connects to your smart home hubs, they also connect many other smart devices or applications, sometimes the usefulness of the connection can be limited. Therefore, when combined with smart thermostats, smart smoke alarms can activate the thermostat to shut down the HVAC system, so that smoke is not drawn into the ventilation system and circulated throughout the home.

Alarm sensitivity and accuracy

Measuring detector sensitivity and accuracy makes it difficult to test smoke/CO detector performance. This shows that smoke simulation can reveal little about detector sensitivity. In addition, you should also consider the general consensus on the underlying technology of the smoke detector. Like Nest Protect, using a split photoelectric sensor is better than the ionization sensor used in older equipment and easier to generate false alarms.

Smoke and CO

You should choose smart smoke alarms for carbon monoxide and secondhand smoke. Some detectors on the market will do both so you don't need to install or buy separate functional equipment, including monitoring batteries in multiple devices. However, smart batteries and smart hearing devices are limited in detecting smoke or CO2 directly, so you need to make sure that your smart smoke alarm can support both detection.

Types of smoke and CO alarms

Smoke alarms

Flames burn differently: there are some flares, some smoldering. There are three types of smoke detectors on the market, but only one is resistant to two types of fire.

Ionizing smoke alarms: capable of detecting small particles of a rapidly spreading fire. But they are quite limited in detecting smoldering, smokey fires. They are susceptible to false alarms for burnt food and steam, and should not be installed near kitchens or bathrooms.

Photoelectric smoke alarms: mainly detects large particles of smoke, smoldering fires but is not effective at detecting fast, burning fires. In general, photovoltaic units are less prone to false alarms due to burning food, suitable in kitchen areas.

Dual sensor smoke alarms: they combine ionization and photoelectric technology to increase detection of burning and smoldering fires, increase good protection and save costs when installing two detectors separate smoke.

Carbon Monoxide alarms

Often carbon monoxide detectors will use a sensor to detect CO in the home. There are still some digital CO level displays, and they can detect and read out CO levels via an audio message. Note carbon monoxide detectors do not detect smoke or explosive gases such as natural gas, propane, and methane.

Place for installing the smart smoke alarms

As mentioned above, smart smoke detectors are a must-have in all homes and carbon monoxide detectors are also essential for any home that uses fuel-burning appliances such as fireplaces, air conditioners, and fireplaces. hot water, range, hob or oven.

While some homes still use electricity to be safe, it is advisable to install a carbon monoxide detector as CO will seep into your home from your garage or if a backup generator is in use near your living areas. during a power outage.

It is recommended that you install smart smoke alarms that detect flare and smoldering fires in bedrooms, install detectors outside the bedroom on each floor, including the finished attic and in the basement. In addition, a carbon monoxide detector should also be placed on each living floor, sleeping area, in the basement, and near the attached garage.

Voice alerts

Depending on the individual will have different sleep states, especially children tend to sleep more deeply than adults and are difficult to wake up according to the alarm. Currently some combined smoke and smoke detectors and carbon monoxide will have voice commands installed. However, this test is also not very positive. According to the study, the percentage of children between 6 and 12 years old awakened to the sound of a pre-recorded voice is higher than the alarm sound.

Which Brands Make The Best Smart Smoke Alarm?

‎‎First Alert

Many great things were born in the '50s. Color TVs, microwave ovens, Velcro, bubble wrap - and the company that created the first residential smoke alarm. In 1958, three friends, Harold Burke, Howard Roberts, and Wayne Kimberline, set out to develop a commercial smoke detector. With the goal to make the world a safer place and gain a collective understanding of a market need to help realize that goal. Burke, Roberts, and Kimberline (B, R, & K), brought their first smoke alarm, the 64TP, to market in 1964.
