My new CO2 monitor arrived today, SwitchBot Meter Pro. Been considering buying this one in the past weeks; there's a lot of monitors in this price range, but generally the build feels nice, app works well, sensors seem accurate and responsive.
First readings I got 666ppm... should I be worried? 😈
I did not purchase the hub or outdoor sensor, so it works via BLE to my smartphone. Overall it seems pretty nice. I'd like an aranet4 at some point as it does VOCs but the step up in price is significant.
