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.

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.

Super irritating alarm that doesn't stop. the alarm disable feature doesn't work. I'm not sure I trust the accuracy of the sensors themselves. bottom line, bad embedded hardware design, sloppy software.

Thanks for the feedback & sorry you found it frustrating. For clarity: the alarm can be silenced instantly with two button presses or by toggling it off/on in the app. If it continued, it’s usually due to missed interaction, not a fault. We rigorously test and calibrate accuracy and encourage contacting support so we can review logs and help.
