      Works, but app could be faster and slicker

      After having a nest protect hardwired into my small house I decided to add two additional smoke detectors in each bedroom for added protection but wanted something cheaper than a nest protect so this was the answer, only issue is, you can’t easily test that the battery is working with the app since it takes it a long time in my opinion to ding your phone that the smoke alarm has sounded. It still works but is a 15-30 second delay sometimes. My alarm company calls quicker than 15 seconds on a monitored smoke alarm, and that’s from it sounding to a person calling you to check on it. For what should be cloud based with no human intervention it should be almost instant maybe 2-3 seconds, but have literally tested them and the alarm sounds for 30 seconds before the app sounds the alarm. Nest is way quicker, litterly instant like a cloud based or internet based system should be. So that being said, the ability to install a cheap connected smoke detector is nice but I wouldn’t rely on this as your only monitored protection since it isn’t that fast in relaying the smoke alarms going off plus if your trapped in the house it doesn’t call for help like a good monitored home alarm system with smoke detectors would. Always have both in my opinion.

      Basic Home Monitoring, Nest Protect is Better

      After purchasing these to monitor two basic smoke detectors for bedrooms, I can say they serve their purpose in alerting you of a fire, but they seem slower than a Nest Protect after the alarm sounds for the alerts to come to your phone, and they don't actively test the alarm since they are just batteries. Great for getting into home monitoring but still think Nest Protect is superior and also a good monitored home alarm system to back it up.

      I looked at many smart home products but did not want to pay lots of money to try things out. This seem like a good idea, to put a smart battery into a smoke detector. The set up was a bit weird, but I got the battery up and running in about 10 mins. So far so good. I going to try it out for a month or so and buy another. one for

      After easily setting up this battery with the iPhone app, I plugged it into my smoke detector and it worked exactly as advertised. Excellent innovation.

      a good & cheap way to make your regular smoke detector smarter. Wish it had an option to give ownership to your significant other/spouse.
