18-in-1 Smart Air Quality Monitor - Indoor WiFi Air Quality Detector with Dual Chip, Real-Time for AQI, CO2, PM2.5, PM1.0, PM10, TVOC, HCHO, Time Display, Temperature & Humidity with APP (Black-Black)

This air quality monitor is easy to install and connects with APP, and the data is easy to read and accurate. A good monitor for home.

This seems like a good quality device. I like the color high-res LCD, sensors, FW updates and good Wifi support. Pairing it with SmartLife was easy and efficient but I wish it also had Google Home support so you can read/control via smart speakers or the Google Assistant - that should be very easy for this company to add via a SW update (same for Alexa, ITTT, etc.) I am reducing one star because of the deceptive "18-in-1" marketing - I don't know how they got to this count, there are roughly 8 sensors here, not 18, but the product description was otherwise accurate.I didn't test it in battery mode since I plan to always it keep it plugged in. Other reviewers mentioned difficulty connecting the USB-C cable but I found it pretty minor, unless you plan to regularly plug and unplug this device.

This air quality monitor is an excellent product—very user-friendly with all parameters clearly displayed. The sleek design adds to its appeal, and the high-quality sensors provide accurate readings.

The screen on this is a proper LCD screen, not some segmented pre-fab'd display, which is a huge plus because it means both that data can be dynamically displayed effectively at high resolution and that firmware updates can fix issues. It seems like this made-in-china design is a nice compact size and offers a decent set of functionality and dedicated CO2/PM sensors rather than trying to just use all-in-one environmental sensors to estimate CO2 and other parameters.There's tons of sensors on the market somewhat similar to this, but I really like this variation. This particular 'PV33' model does also seem to be sold under several names on different marketplaces, but I suspect they're all from the same OEM. I liked that this one specifically was Tuya Smart because it meant that I likely would be able to (with some work) get it to work with home assistant offline without the Tuya cloud. This does appear to be the case with HACS + Tuya Local (not yet fully supported, but works as the '8 in 1 air quality' type right now). I updated the firmware using the Tuya Smart Life app immediately to the latest version as there was an update available for the unit.Screenshots of the manual and some of the screens included here for reference. I mounted this in my workshop and connected it to a USB power supply, although I was surprised to find it also has a built-in battery that they claim can last for 6-12 hours.. useful if you need to bring it into a different area I guess ?

Overall, the product is pretty good, but the main disappointment is the poor battery life in addition to not being able to set the time to a 12-hour format. Unbeknownst to me, the product has to be connected to a power source throughout the day in order to obtain maximum utilization since the battery isn’t able to provide more than eight hours of power. The other annoying design flaw is the accessibility of the USB-C port, which requires the back cover to be removed each time you want to access the USB-C port for charging the device. The only reason I’m giving this product a three-star rating instead of a two-star rating is due to the seller’s detailed customer service explanation; they did an excellent job explaining the different constraints that currently exist with the product. Hopefully they’ll make some modifications to the product design to improve customer usability.

The device appears to function properly. Set up was easy. It would be nice if its accompanying Mobile app provided definitions of the acronyms displayed. I keep it plugged in to avoid the low battery issue cited in other reviews.

Easy to set up. I moved into a new apartment and wanted to check the HCHO and TVOC numbers. This little one does a good job! The LED screen is o good quality.

Great product. Very easy to use it shows all the parameters clearly . Design is very sleek . It have a great sensors which give us accurate values
