The device works reliably. I cannot assess the accuracy of the measurements. However, the differences between different rooms are immediately recognizable. The display of temperature and humidity is not accurate at all. However, I have calibrated measuring devices for that. Inside the device, the gas sensors need to be heated. Therefore, the temperature and humidity inside the housing cannot be the same as the surrounding air. For me, a good device.

Das Gerät arbeitet zuverlässig. Die Genauigkeit der Messungen kann Ich nicht beurteilen. Die Unterschiede zwischen verschiedenen Räumen sind aber sofort erkennbar. Die Anzeige von Temperatur und Luftfeuchte stimmen gar nicht. Dafür habe Ich aber geeichte Messgeräte. Im Inneren des Gerätes müssen die Gassensoren erwärmt werden. Deshalb können Temperatur und Feuchte im Gehäuse nicht so wie die Umgebungsluft sein. Für Mich ein Gutes Gerät.

The product works, but unfortunately it works much less with a charged battery than described. Even on a full charge, it only lasts 1.5-2 hours, which is not enough for the battery power. It also regularly switches off completely. After turning it on, you can see that it still has charge, so I dont understand why it is doing this. It also does not collect data after power off, so it does not send it to the app.
