Sending data to the display

[8666]

I have different Station WH0531 (temperature and rain) and I am in the process of decoding it with the help of your code. The message is the same format. How complicated is it to emulate weather station so I can display my own data on the inside screen?

The outdoor temperature sensor is not very precise so I want to display the data from other sensor. Will make the weather station silent first.
