The 2nd Gen. Nest Protect Smoke Alarm also detects carbon monoxide, connects via your smartphone: $81 (Reg. $99)

Staples is currently offering the Nest Protect Smoke and Carbon Monoxide Detector (2nd Gen., Battery-Powered) for $80.72 shipped when you add $1 worth of filler items (like these pens) and apply coupon code 97080 at checkout. For comparison, it sells for $99 at every online retailer including Amazon and rarely drops below $90. Today’s deal is the best offer available.

Nest Protect connects to your Wi-Fi and monitors both smoke and carbon monoxide in your home. It works with the Nest Thermostat (not required) plus it can alert you via your smartphone as well. It has a “friendly voice alert” system that won’t alarm you too badly if the toast is burning. Over 3,300 Amazon customers have left an impressive 4.7/5 star rating.

Both the wired and battery versions of Nest Protect take only minutes to set up with your iPhone, iPad, or Android device. Once they’re connected to Wi-Fi, every Nest Protect in your home will automatically connect to the others. The Nest Protect is also easier to attach to the wall or ceiling thanks to a redesigned backplate. Nest Protect has been redesigned from the inside out. It has an industrial-grade smoke sensor, can be hushed from your phone, tests itself automatically, and lasts up to 10 years. And just like the original Nest Protect, it also tells you what’s wrong and can even alert your phone.
