Frequently Asked Questions About Smart Alarms

How many smart alarms does BestPriceScanner track?

We currently track 29 smart alarms with prices ranging from $15 to $170. Popular brands in this category include Kidde, Smart Caregiver Corporation and X-Sense. Every product is updated hourly across Amazon, Best Buy, Walmart and EcoFlow.

What is the cheapest Smart Alarm right now?

The lowest-priced smart alarm we're tracking starts at $15. Sort by "Price: Low to High" above to see the most affordable options first. Keep in mind that prices change frequently, so what's cheapest today may shift tomorrow.

How can I get notified when smart alarms go on sale?

Open any product page and click "Set Price Drop Alert." Enter the price you're willing to pay and we'll email you the moment it drops to that level or below. There's no limit on how many alerts you can set, and it's completely free.

Are smart alarms cheaper on Amazon or Best Buy?

Neither retailer is consistently cheaper. Amazon often wins on Kidde, Smart Caregiver Corporation and X-Sense products, but Best Buy runs exclusive promotions and open-box deals that can beat Amazon's price. Walmart occasionally has the lowest price on popular models. That's why we compare all three in one place so you don't have to check each site separately.

How many smart alarms are on sale right now?

Right now, 13 smart alarms are at a reduced price or at an all-time low. Look for the orange "All-Time Low" badge or the green "Save" badge on product cards above. You can also sort by "Biggest Discount" to see the largest price drops first.
