1. A method of operating a wind turbine during a service, wherein the wind turbine comprises a rotor-nacelle assembly comprising a rotor, the method comprising:
detecting, based on data from one or more sensors embedded within a wind turbine, that a service is to be or is being carried out on the rotor-nacelle assembly of the wind turbine by detecting a selection of the rotor-nacelle assembly for service, and detecting a presence of personnel in a vicinity of the rotor-nacelle assembly; and
on detecting that the service is to be or is being carried out on the rotor-nacelle assembly:
reducing an operating level of the rotor-nacelle assembly; and
reducing an overspeed threshold or an overpower threshold of the rotor by an amount greater than an amount by which the operating level of the rotor-nacelle assembly is reduced.
