Current status

I have used these devices for several years and generally they work OK. The time setting seems to be fixed and varies quite a bit between individual sensors. It would nice to be able to reset it to correct synchronicity. Today the App seems to have stopped working and is giving garbage readouts. I have deleted it and reinstalled it but it still seems to no longer work.
The App no longer shows the pie chart only the bar chart. This is a reduction in usefulness of the App. This is with iPhone 16.

Can not calibrate

Calibration does not work

Sehr gut für den fünften Stern wären Unterstützung von Kurzbefehlen super 👍

App macht was sie soll. Nutze diese zusammen mit einem BT Thermometer um die Temperaturim Kofferraum für meine Hunde zu ermitteln. Das funktioniert super nur leider muss ich dafür während der Fahrt das iPhone in die Hand nehmen. Was großartig wäre wenn ich per Kurzbefehle die Aktuelle Temperatur über Siri angesagt bekomme oder eine Warnung wenn eine Temperatur überschritten wird und ich mit CarPlay verbunden bin.

No problems with hygrometer

Have been running these for a few years with no problems. Had to properly calibrate them as a few degrees off for both temp and humidity but the software has an inbuilt tool for that . Also you have set up a new log when the battery dies and the device resets but again not difficult. The developer of the App is good and responsive - I found a bug and he fixed it . Can’t ask for mor than that 😀. I read another review for the product that was bad but the person clearly didn’t understand how to reset the device after battery change so more of a user issue..

Response from developer

Hello, please update to the V3.4.4 and see whether still happen on your phone.

Sensor friert ein

Leider hat sich am zweiten Tag der Nutzung schon einer der drei genutzten Sensoren nicht mehr gemeldet und das Bild blieb eingefroren. Der Sensor war nur noch grau hinterlegt und nicht wie bei den aktuellen und angebundenen Sensoren grün. Auch ein Refresh hat nicht geholfen, dass aktuelle Daten angezeigt wurden. Ich musste den Sensor komplett aus der App löschen und neu installieren, so dass ich wieder aktuelle Daten bekomme. Bin gespannt, wie lange diesmal die Verbindung bestehen bleibt.
