A printer kept dark between uses showed a black live view and sent black notification photos (#1655). Settings → Camera can turn the light on for all printers or for selected ones, for the live view, notification photos, the finish photo and the snapshot API that Home Assistant uses, and turns it off 15 seconds after the last use. It only turns off a light it turned on, and switching the light by hand hands it back. Snapshots wait an adjustable delay after the light comes on. Timelapse, the Obico check and the in-print frame bank don't switch it, since they would make it flash. The camera card no longer lists every printer: external cameras are added from a searchable printer picker and only those printers are listed, so large farms get a short page.
