  • Easy installation, absolutely SPECTACULAR user interface!
Style: Battery
A year ago, I purchased a first generation Nest protect (battery only), but didn't install it because one of its features was disabled by the company (waving to silence alarms) and all the detectors in my home were integrated by a/c current. Two weeks ago, just as we were preparing for a trip away, the smoke alarm near the entry way began chirping and beeping (two different sounds). We were able to silence the chirp with a new 9 volt battery, but the only thing that would stop the beeping was to turn off the power to the a/c circuit to which it was connected. Even totally removing the malfunctioning unit didn't silence the beeps! Descriptions of our dilemma provided us no clues, but eventually, we contacted telephone support for the unit's manufacturer. A REAL LIVE PERSON with concern and humor answered, listened to me describe our problem, then responded, "honey, the ceiling can't beep! Do you have a CO monitor close by?" We did. She then told us that the beeping was the "end-of-life" signal coming from the CO monitor plugged in at ground level 10 feet away. Sure enough, unplugging it silenced the beeping. Then she told us that our other CO alarms and all of our smoke detectors were well beyond their intended lifespan (all manufactured in 1992) and all of them must be removed, even though they all displayed their "AOK" green LEDs and passed their aural tests). (We purchased this home 2 years ago, paid several hundred dollars for a home inspection, and nothing in the inspector's report mentioned that our detectors were beyond their expected usable lifetime). Clearly, we needed protection that gave us more feedback about their normal and abnormal performance. Extraordinarily satisfied with our Nest thermostat, I decided to purchase Nest Protects for the rest of the house. I installed the 1st generation unit to replace the one I'd already removed. To do so, I needed to drill some holes into the ceiling because the holes for its mounting plate didn't line up with the junction box in the ceiling, and two of them required a power drill in order to penetrate the 2 x 4 ceiling framing. We left on our short trip knowing that we had at least one working device and several more to install when we returned home. When we returned, we unpacked the new, a/c powered units, lined them all up within 20 feet of the 1st generation battery operated unit, and began the ID/registration process. The thought that's gone in to the user interface for this device immediately became obvious, when a quick routine of scanning the code on the back of each device led to prompt addition of it to our existing network of Nest thermostat and an increasing number of registered Nest Protects. Physical installation went just as quickly, as did an initial "checkup" initiated from my iPhone. I did spend a few minutes reading the manual, and learned that 10 years from now, when units require replacement, they'll alert me both verbally when I'm in their proximity, and by sending me emails that they're in need of replacement! Another plus: the thermostat in our 2 story home is located in a small blind corridor where it cannot "see" traffic through the rest of the home. Consequently, when we're asleep at night, our Nest Thermostat decides we're away, and the temperature drops to the "auto away" setting during the night. We save big on our power bills but it gets a bit cool in the house! Now, with the Nest Protects "talking" to the thermostat, we awake to more comfortable temperatures. I have only two concerns about these devices. One is that, in a very large home, the "checkup" testing of individual devices may overlap others in time. That's not a problem in our relatively small 2 story house, but in a large home the overlaps could make it difficult for one person to confirm that all the units are working. Even that's not a real issue, because the units test THEMSELVES when we're not present and send us email confirmation that they're all functioning. The other concern is that these products were born in the minds of people who worked at Apple, who clearly learned their lessons well while there. They are attractive, communicate clearly to their owners, and guide their owners with an outstanding user interface. Unfortunately, the company has been purchased by Google, and it's entirely possible that the business goals of these two no-longer-friendly companies will deprecated their future as anchors of a "connected home" where "works with Google" will mean "won't work with Apple." ... show more
