Browan tabs legible payload?

Hi, I bought a browan tabs (tbh100). Unfortunately I don’t see a valid payload in TTN. How do I get the temperature and humidity legible? Best to go straight to MQTT?
Regards and thanks for help., Thomas

Did you install a payload formatter for the application or the device?

Hello,
no, what exactly do I have to enter for the ‘tabs’?
Sry, is my first device with TTN.
