The BiWiki documentation is describing the disableRemoteSensor as "Disable raycasts for remote entities in a group that doesn't have any local entities. "

If the command is to be used locally and is applied to groups why not rather have a semantic as:

_group disableRemoteSensor _bool;

where the _group is a local group. This whould allow to have better granularity when trying to optimise a mission/scenario.
