Update a machine

update_machine

Destructive

Correct a registered machine (its name, control type, prep type and style, basket, boiler, accessories or notes), or record where its selectors stand (settings). Only the keys you send in fields change; send null to clear an optional field (an empty string also clears a text field, but not a number or a closed list). Required fields can be changed but not cleared. fields may be omitted when only reason is sent. prep_style decides whether shots on this machine are diagnosed at all: only "espresso" is. Programs are edited with register_program, the built-in grinder link is not editable here, and archiving is set_equipment_archived.
