A few weeks ago when I got home from a trip to Boston, I found that my smoke alarms were chirping. (I have 3.) They are hard wired, and usually when you change one battery, you have to change them all. I assumed the chirping was a battery issue, so I swapped them out for new…but the chirping continued. I came to realize, it wasn’t a battery issue, it was a product issue. Apparently smoke alarms need replaced about every 8 years. We build this house 8 years ago, so it makes sense. I hated the ugly smoke alarms that the builder added to each floor. And I hated having to fan the one near the kitchen incessantly anytime it thought something in the oven was burning. (Even was it wasn’t.) So, I did my research to find a better system. I ended up going with nest. We have a nest thermostat, so this made sense. I love that you can just hit a button on your app if your oven sets it off, rather than stand under it waving a towel viciously. I also love that I’ll het a notification if something is burning when I’m not home. Lastly, I love that it lights up at night when you walk under it. I bought 3, one for each floor, and I’m so glad I did! (*They also are a carbon monoxide detector, in addition to just smoke.) LTKHome
