App and device still seem flaky. E.g. settings change or screen won't turn off automatically sometimes, but works fine after a cold reboot. Connecting a new device may need some patience, instructions differ slightly between app, print and online. It seems to be important to have power connected during the process. Needs nearby devices and location permission permanently, which I wish would only be required during setup. Once configured, the device is really good, especially for the price.

This app appears to be halfway developed. PM 2.5 alarm should have much lower threshold because 16 is when you would be already in serious trouble. It should start at 1 and go up from there. Who did you pay to design this?! The EPA says a lot of things and intelligent people know to research these things for themselves. The US stamp of approval goes on all sorts of terrible things.

Thanks for your feedback. The thresholds follow guidance from the US EPA, based on decades of peer-reviewed environmental health research. While individuals are absolutely free to interpret air-quality data differently, we chose to align the app with widely recognized public-health standards rather than personal interpretations from online sources

I love It. I now know that the CO2 values in the bedroom are higher than I thought. When cleaning the PM values go really high so I know it works. The only thing is with the widget. It says: no controllable devices. However, if I click on it I see all the information, so the connection is there. I hope you update and fix this soon.
