Very easy to install -- works well; but be sure you have space in your junction box for the hub,
This is one of the few "internet of things" or connected devices that really makes sense.
For one, it's a multiple function device. Fire and smoke alarm; carbon monoxide detector, and an indoor air quality monitor. The air monitor keeps separate temperature, humidity, and air quality records and reports the health of each in traffic-light style (green, yellow, red), Very helpful and suggests ways to improve if needed.
All of the functions report on line and can be accessed from an app on a phone or tablet.
Alarms are reported in real time to your devices so you can be aware of an event if you are not home.
You can share the device access with friends or family members, so this is a great tool for remote monitoring of relatives or friends. It can work in the reverse, too -- so I am keeping track of my house and my elderly parents house in one app. Peace of mind for me. Likewise a good choice for a second home or even an RV where remote monitoring is desirable..
Installation is simple with clear, in-app directions; however, the alarm-detector only uses 2.4 band WiFi, so if the phone or tablet you are using to install the device is on a different Wifi band, you will need to change it to 2.4 for fastest results.
The device connected to our WiFi easily and then updated its firmware. It reported temperature and humidity right away but takes four days to calibrate the volatile organics component of the air quality. Once that was done, everything appeared in a well-designed, easy-to-use app,
The devices can be interconnected throughout one location so that if an event is detected at one station, the others will sound.
The wiring harness was the same as a 20-year old detector I replaced, so there was no need to change it.
The battery is internal and lasts 10 years. It cannot be replaced, so the entire device must be replaced when it's 10 years have elapsed. The app keeps track and reminds you when that point comes near.
Perhaps the best feature is the WiFi hush option -- no need to manually hush the detector, although that option is available too,
Well engineered -- the LED light on the detector slowly fades to off when night (darkness) is detected so one fewer bright LED light to keep you awake. The LED fades back to life when ambient light is detected.
Multiple variants that include any of the three features -- smoke and fire, carbon monoxide, and indoor air quality.
The IAQ monitor is very sensitive and accurate -- it reported very bad indoor air after I cooked dinner -- so if you are not the best cook or don't use the ventilation fans, be prepared for that notice.
On-line records are kept in the cloud for free. There is an option for a monthly fee, but I haven't yet investigated whether it's worthwhile.
One factor to consider: There is a rather large hub on the back side of the detector that needs to be accommodated in your junction box. If your box is crowded with wires or is not deep enough, you may not be able to install the detector. Be sure to measure before ordering.
Note: requires 120 volts to work (the battery is for backup) and WiFi for monitoring and reporting.
It is considerably more expensive than an ordinary smoke alarm, but adding in all of the features and components makes it a good value. What's more, the remote monitoring is very beneficial with everything consolidated into one app.
The instruction booklet is very detailed and gives clear directions on where to install the detectors. I think it's a good idea to review this section and be sure your alarms are properly positioned and that you have them in all of the recommended locations. This is especially important in older homes or where building codes have been updated.
