What nickrout tries to tell you is that we don’t have a crystall ball. You are only posting a small part of your yaml, however the update of a screen is also depending on f.i. the update_interval you are using in the display statement but also what kind of sensors you are using and their update_interval. You are using a script, but we can’t see the content of that script, so how are we supposed to help you. See also How to help us help you - or How to ask a good question
