How Get Average and Maximum Value of my temperature sensor

How Get Average and Maximum Value of my temperature sensor

Hi,

I'm new in de IOT community and try to discover the system with a my cucumber greenhouse.

I installed a dragino LHT65 temps sensor and I set it correclty on my dashboard. The problem is I would like to have the last 24h Average temperature + the max 24h temperature...

I don't know how to do that because it's apparently need some data calculation and probably need to create a variable.

Thx for your help.
