Liebe Community,
ich möchte gerne den Zuwachs an Senseboxen visuell gestalten und würde gerne wissen ob es geht, abzufragen wie viele Senseboxen an einem bestimmten Datum erfasst waren. Würde mich freuen wenn es tatsächlich geht

Hi @Olli,
eine direkte Abfragemöglichkeit gibt es nicht. Jedoch hat jede senseBox ein createdAt Attribute.
Hier ein Beispiel für eine senseBox (abgefragt mit https://api.testing.opensensemap.org/boxes/5b0d3d5bd40a290019ef42b5):
{"_id":"5b0d3d5bd40a290019ef42b5","createdAt":"2018-05-29T11:45:31.324Z","updatedAt":"2018-11-20T18:54:02.398Z","name":"senseBox-MCU WiFi Test","currentLocation":{"type":"Point","coordinates":[7.597089,51.961007],"timestamp":"2018-05-29T12:16:27.926Z"},"exposure":"indoor","sensors":[{"title":"Temperatur","unit":"°C","sensorType":"HDC1080","icon":"osem-thermometer","_id":"5b0d3d5bd40a290019ef42bc","lastMeasurement":null},{"title":"rel.

Das könntest du nutzen um zu schauen, wann wie viele Stationen erstellt wurden.
Beste Grüße,
