uHoo 9-in-1 Smart Air Quality Monitor Indoor, Smart Temperature Sensor, Smart Humidity Sensor, CO2 Monitor, and Mold Detector for Home with Free Mobile App

I've had my unit for almost a year now, there have been a lot of bugs, but the uHoo team seems to be continually iterating and building upon the app. It's definitely a much stronger, more reliable tool than when I bought it. Probably for the first nine months my NO2 and O3 readings were always off the charts, and I basically learned to ignore them as I still got mostly reliable info from CO2, PM3, and TVOC which were the most critical metrics for me. Eventually, I contacted the team about this bug and it got fixed within a few days. It seemed like a bug that was impacting only my unit. There have been a few other hiccups, but they were random and I've learned to deal with them, but as of the last couple of months I haven't seen many, if any, bugs, and the app has a much better UX.I'm looking forward to using the IFTTT features soon, it's the feature with the most potential. Right now, IFTTT doesn't seem to be very robust and that could be due to being new to it. I imagine the uHoo team will continue iterating on the ability of the end-user to access the data. Previously I wasn't planning on buying anymore of these, but since the app and reliability have improved, I will be buying another couple of units once I find enough free time to comfortably navigate IFTTT and data exporting to justify the cost.In about a year or two, I plan on constructing a house and it would be great to see an expansion of this product into something that can be incorporated into said construction and not something merely designed for a table or counter top. Maybe something that looks like a smoke alarm and mounts to the ceiling powered by a lithium battery with the ability to connect to WiFi / LiFi. Also on the wish list would be a sensor for Radon.

Potentially great product ruined by bad software, onboarding.I am Cisco Certified Network Professional with decades of network and IT experience. I also develop IOT in my spare time, and have tons of home automation experience. When I say this thing is a failure, I am not joking.The fundamental flaw is trying to "Magically" "Make Easy" the addition of IOT devices like this. They TRY to leverage your existing WiFi account information. To do this, you must enable location services, including detailed location information.Uhoo software engineers thought it would be easiest to identify your existing Wi-Fi network, then pivot to joining the devices WI-Fi, and ultimately pass this information over to it. This is just dumb. On an IOS/iPhone device you are jumping between Settings| Uhoo | Settings | Uhoo. The extra step in trying to harvest your Wi-FI information is unnecessary and the reason people fail to get this set up. As we enter 2021, cybersecurity is interrupting this concept.****** All Uhoo should have done was allow you to connect to their temporary unsecured Wi-Fi hotspot, and allow you to manually enter you Wi-Fi network credentials! -or kick it old school and let me do it from a Web Browser 192.168.style *******For those that managed to get this working, they probably got it working before Apple and Android added more security to the operating systems. Somewhere there is a sweet spot like 13.0.I attempted to get this thing working with the following:1 - iPhone 8 (IOS 14.2) (A dedicated IOT iPhone)2 - iPhone 6 (IOS 14.1)3 - iPad Air (IOS 12.4.7) (Surprised this failed actually)4 - iPhone 11 (IOS 14.2)5 - LG Android PhoneNOTE: The Uhoo App on the Apple App Store is currently 2 Stars! It is bad!On the iPhone 8 the app crashed 90% of the time when trying to pivot back and forth from your network to joining its hotspot.iPhone 6s I managed to get the furthest with no app crashes, but it failed to add the deviceiPad Air same issues as iPhone 8Android. This got interesting as I discovered another fatal flaw in their onboarding/adding device process. On Android if you attempt to join a Network (in this case their UhooXXXXXXX hotspot), without Internet access, Android will fail back to a Network, LTE, that can speak to the Google Mothership. So I tried forgetting all working Wi-Fi networks, turning off the LTE access, and Android basically kept Disabling networking when connecting to UhooXXXXXX. - So I gave up.I also thought maybe my advanced network was an issue. So I dragged out an old, but updated, Asus RT-N66U Wi-Fi Router with only 2.4Ghz enabled and very "forgiving". - NOPE, that did help either.Final thoughts. IOT Device Developers can NOT rely on IOS/Apple/Android operating system "hacks" to onboard their devices to your network. It is great if it works, but a secondary method needs to be available like the old school "Connect to it over 192.168.x.x., and add WiFi".Final thought #2: ADD AN ETHERNET PORT! Even if only used to add WiFi credentials. Better yet all IOT devices would ideally have Ethernet & POE to power it.Until Uhoo fixes their App run away.

The uHoo continuously measures temperature, humidity and atmospheric pressure plus 6 separate indicators of room air quality. It is relatively unobtrusive and can be set-up and linked to your IOS or Android device in just a few minutes. I originally bought the device to monitor my bedroom air quality because I have an allergic lung disease which makes me very sensitive to small particulates, volatile chemicals and ozone in the air, all of which are monitored by uHoo. I never dreamed that this device would save me from a serious illness or worse! I was awakened by an alert on my cell phone at about 5 AM one morning. My uHoo was sending an alert that the CO2 levels in my bedroom were high. In fact, the measured CO2 level was 1675 ppm (greater than 1000 ppm is considered dangerous). My husband and I both had headaches and we felt weak and nauseous. When I realized what was going on, I got up and turned off the house HVAC system and opened some windows. The CO2 levels dropped rapidly after that and we began feeling better. It turns out that we were having the shingles on our roof replaced and when the worker's left that afternoon, they had covered parts of the roof with plastic to protect those areas from nighttime moisture. In so doing, they inadvertently covered the exhaust vent to the house HVAC system. This caused CO2 to be released into the house and the levels built up quickly since the night was relatively cold. Who knows what would have happened if we didn't have uHoo to awake us and warn us? I now consider our uHoo an essential house safety device! You never know when something like this will occur.
