Payload can not be analysed to temperature

Hello Everyone,
I just started to learn this stuff. And I ran into many problem.
Now I connected my sensor and gateway with ttn. And I can see some data from my sensor. Payload formats is Cayenne Lpp. But payload still can not be showed as temperature.
If some professional guy can help me to solve it? Thank u very much.

In the console, under ‘Applications’, there is a ‘Payload formatters’ section, use that to select ‘Cayenne’.
Then make sure your device uses the application defined payload formatter.
