Calibrate shutters

how can I calibrate my shutters with home assist . currently the 100% doesn’t close all the way

Please provide a little more information. I’d start with the brand and how you have the blinds integrated.

Hi , I have tuya switches for the blinds , I managed to calbrate it in the past but now It stoped working and I get the followig message “This entity is no longer being provided by the mqtt integration. If the entity is no longer in use, delete it in settings.”
