if self.scan_item is None:
self.update_with_scan_history(-1)
# If scan_item is None, than update_with_scan_history will call `_categorise_device_curves` via
# `_emit_signal_update`. All of this happens while old_scan_id is still set. So we actually register
# a callback twice for the same scan_id. This is a problem since data will be duplicated.
