Triggered when the home type changes and when setting a new home type has been refused by the drone.

command messageolympe.messages.rth.set_home_to_takeoff_location(_timeout=10, _no_expect=False, _float_tol=(1e-07, 1e-09))

Rth.Set_home_to_takeoff_location

Result: If the [takeoff location](takeoff_location()) is known, (i.e. if the drone has fixed), home_type() is sent with type = takeoff, otherwise it is sent back with the former home type.

Expectations: home_type(type='takeoff', _policy='wait')
