Ja sicher @jensileinchen,
ganz einfache Code wobei ich auf die alte TTNv2 Platform noch mit ABP und Cayenne LPP die Feinstaub und HDC1080 Werten verschickt habe. Nicht CO² weil ich dafür MQTT und Wifi gebraucht habe um diese Werte zu visualisieren.
Die AppSkey und NwsKey is aber camoufliert herunter. Im Blockly einfach zu herstellen.
Der Grund warum ich die alte TTNv2 brauchte ist das für den Sensebox MCU v1.5 das Probleme gab. Wahrseinlich das sensebox.h im Blockly noch nicht up to date mit die neuen Libraries. Die Demo musste schnell gehen auf meiner Stelle, deswegen ABP und TTNv2 das immer stabiel funktioniert.
