SwitchBot Meter Pro CO2 Indoor Air Quality Monitor 5-in-1, CO2 Alarm, Large Display, Bluetooth Air Quality Tester for Home, Office, 2-Year Data Storage

The SwitchBot Meter Pro CO2 Indoor Air Quality Monitor is an excellent tool for maintaining a healthy environment. Its 5-in-1 functionality provides real-time CO2 readings alongside temperature, humidity, and more, making it versatile for home or office use. The large display is easy to read, and the Bluetooth connectivity ensures seamless data tracking with 2-year data storage to monitor trends over time. This will save my home from potentially health issues.I paired it with the SwitchBot 4-in-1 Air Purifier, and they work perfectly together. The purifier’s H13 HEPA filter and aromatherapy feature not only improve air quality but also create a pleasant atmosphere. Its RGB lighting adds a stylish touch, and the combination ensures I can monitor and purify the air simultaneously. This duo is a fantastic investment for anyone prioritizing health and comfort.

$69 with a 30% off coupon is a great price! They used the industry's best NIDR sensor for CO2 readings. I don’t have a Hub, but the setup is simple. I added it to Home Assistant via Bluetooth, and it works perfectly.I am comparing it to the Aranet4 for accuracy, and the readings are similar, with less than a 50 ppm difference between them. I have included a comparison graph for your reference; the yellow line represents the Switch Bot, while the blue line represents the Aranet4.The only downside is that when running on battery, the CO2 reading is recorded every 30 minutes, but when plugged in with a USB-C power cable, the readings occur much more frequently.Overall, I am happy with my purchase and plan to buy more units for each bedroom.

For my purposes I need relatively frequent readings, and this meter is not optimal for this need. I decided to keep it anyway as it does work well . Customer support was excellent and they offered to refund me without even returning the item.

I wanted another CO monitor, but this is a CO2 monitor. Be careful. As I was trying it out, saw the CO2 level going up, my wife was frying something, and forgot to turn on the vent. Levels were red. I open the vents, and windows, and levels came back down to acceptable range. So now I will keep it on the kitchen counter for my wife.

Shocking how high our CO2 levels are when everyone is home and in the same room. I love the large display and ability to integrate with Home Assistant. Knowing what's going on helps to encourage healthier habits like getting more plants and doing any air exchange we can when the weather is in our favor. Too bad HRV are so expensive. Everyone should probably have one!

I really wanted to like this. The size and form factor are great, readability is good, the app is really well done (much better than Inkbirds).But I cannot get consistent accurate readings when compared to the Aranet and Inkbird and Life Basis (not pictured). I did do a calibration upon opening. This involved setting calibration mode on the app and putting the device outside for a little while. Temperature and humidity readings appear good.Unsure on battery life as I am returning. Price was good, but doesn't matter if it doesn't work.

Easy to setup and works

I bought this before I realized a newer version was available and maybe I should have waited.The device itself seems to be working well so far, though I don't have another CO2 meter to test it's accuracy. I absolutely love the ability to check the meter from the mobile app on my phone, however there have been several occasions that I've lost connectivity to the device for no noticeable reason hence the 1 star deduction. Regardless, it's solid performance and cheap price still make this an easy to recommend product.
