the binding immediately gets the updates - if present. So, if anything you had to find a way to configure the update interval within the Xiaomi System - e.g. per device or within the Gateway. I don’t see something that way - and I assume the devices themselves only update if needed - to save energy.
Long Story short: we have to live with it - but all real-time dependent Actions (e.g. buttons or Alarms) will get immediate Response. non-vital Information (temperature, pressure - and like here Illumination) update “at will”
