Hey there!
is there a way to use addhost.php to add hosts and in the same line override the Override sysLocation: for that device?
or is there another cli command to set the sysLocation for a given host?
i have about 400 devices to add to librenms, and the syslocations in all the devices arent usable,
so i’d lige to make a script and import them that way.
Thanks for the help! 
None of that is possible I’m afraid.
However you’re going about it the wrong way https://docs.librenms.org/Support/Configuration/#location-mapping
i did a script that ssh the device, changed the config, commited, then exit.
then i put that in a batch script with external vars, so i set the values correcly on all the devices in a jiffy
imho I would suggest making a script to correct the syslocations on the devices itself instead of trying to fix it on librenms side.
It will be a big job but in the end it is better to have the correct info on the source.
actually it dodnt take more than an hour, and its usefull at other things as well
