LibreNMS groups by vendor

i am having hard time to create a group on basis of vendor.we have 50 location who have their smart UPS installed and vendor is i want to create a group by vendor so that all ups show under that group but i have no idea how to achieve it .any kind of help in this regard would be highly appreciated …thanks a lot

What have you tried? What were the results? What are the expected results?

i went to devices tap then manage groups then i am trying to find a pattern there…like vendor but its not there
like devices.vendor and then condition is equals and value should be name of the vendor thats what i am trying to do so far please guide me in the right direction thanks a lot

maybe try out device os
