The readings were ok and display was satisfactory but it would not connect to wifi. Followed setup instructions and contacted their tech support but that was no help. It continued to fail connect attempt. Returned it for a refund and ordered a different brand that connected to wifi 1st attempt.

I bought the CO2 meter 6 months ago. It setup and worked well. I only locationally use the app/WiFi connection as the display is so easy to read from any angle. At some point the WiFi fell off as I tried to remotely access and could not. I tried to connect it to the original network and it would not connect. Tried a couple other networks and it would not connect. Contacted customer support and provided my trouble shooting and answered some questions. They sent me a replacement which setup and connected to WiFi right away. There is a notification for offline in the app which I guess I will activate. Even though the WiFi failed the unit still showed the correct temp and humidity. And the meter reported CO2 which moved as expected with changes in the environment. This is a great meter which is very easy to read.

There are many good reasons to have a CO2 monitor. I bought it because I am interested in growing plants indoors. We also have a gas fireplace, however, which makes monitoring CO2 levels important for health and safety. It’s interesting to see how much the CO2 level changes. The graph on the phone app makes it is easy to see how the CO2 level changes.The setup was easy. The device was already charged right out of the box. Calibration was surprisingly simple—just take it outside, push three buttons at the same time and let it sit for 200 seconds. As luck would have it, a delivery truck stopped in front of our house and left the motor running just as I pushed the buttons. I could smell it so it must have affected the CO2 level in the ambient air. So, I had to calibrate it again. It’s good that it’s so easy to do. Just be sure to keep it away from traffic during calibration.The display is very understandable and can easily be read from across a room. In addition to the CO2 level, it also shows temperature and relative humidity. That’s very helpful for monitoring indoor growing areas. The display can be turned on and off simply by pressing a button on the top of the device.I use the phone app when I’m away. In addition to being convenient, it has more capabilities—like graphs. I have two other Ink Bird devices, so I already had the app installed, which made installing the third device very easy. The app has features specific to each device. Because it’s WiFi, the status can be viewed almost anywhere.

I have been using the Wifi InkBird CO2 monitor for a month and it is amazing. First, quality, it is well built and a great size. The screen is big and bright, very easy to read. It actually came charged. I took it outside and calibrated as suggested in the directions. It’s registered CO2 levels over 1200 for roughly 3 days and then began to drop. I assume the sensor was adjusting. My house regularly sits around 450ppm. Although it does go much higher when my wife and kids are home during the day. The app is great. Same app as the WiFi temperature/humidity sensor. The app is easy to use and logs the readings from the device. I have my CO2 monitor sitting next to my reef aquarium and it has been invaluable. When my pH probe can’t get over 8, it makes sense as the monitor is reading high CO2. This was definitely worth the money. One happy customer here.

Man this thing saved my legs! I was continuously running up and down stairs trying to make sure my plants environment was top notch!Not only is the display easy to read on this even through the net - using the Wi-Fi app is literally worth the price right thereeasy to set up, quick readings and since I am putting a focus on my C02 levels - I can set when I want it to alert me from my levels.battery life is pretty darn good, but having a rechargeable one instead of constantly spending money on batteries - done and done!GOLD!

Pros: This monitor is well-designed and has a bright, easy to read screen. It has a rechargeable battery, so it can run for sometime without being plugged in.Cons: For some reason this monitor only works with the provided USB-A to USB-C cable. Literally no other working USB-C cable that I have at home works with it. I don't know the reason for that, but that severely limits the usefulness of the monitor, since I wanted to use a longer cable to put the monitor on a shelf, and now I can't.

I’ve been using this meter to read co2 levels in a garden for the past 2 months, it seems to be relatively accurate but I don’t have another meter to compare it to. It has a calibration setting to recalibrate by holding a few buttons. It’s fairly easy to use, the instructions are clear, the screen is nice and bright and legible. The battery is a nice touch but it doesn’t last long, obviously. Mine is kept plugged in 24/7. My only gripe is it didn’t come with a usb outlet adapter, just the cable. The power input is USB-C which is great. Very reasonably priced. The temp and humidity seems to be off by a couple of points here and there but for the most part it’s accurate.

This is advertised as having an NDIR sensor for CO2. The sensor reading increases in response to alcohol nearby, for example hand sanitizer, suggesting it may actually be measuring VOC. In a side by side comparison, the Aranet4 did not react to alcohol.Also, the humidity readings were 30% different than 3 other nearby devices.The data from this device did not seem trustworthy, and it was returned.
