Hi @glaukelshani ,
There is some conversion that happens when going from EPW data, which starts at 1:00 on January 1 and Wea data, which starts at 0:30 so perhaps that’s what you are experiencing. Can you try using the new LBT Ladybug that was released yesterday?
You will see that the new Ladybug Plugin has full support for real-time radiation and thigs will generally be much easier to debug in the new plugin.
