Update add_device_type_components.py

Update so "Devices" also filters on manufacturer, not just model

[candlerb]

I don't think this is necessary, can you explain why you think it is?

Device type is already filtered by manufacturer: the only reason for presenting manufacturer as an input is to reduce the length of the list of device types.

Whilst device types don't have unique names (you can have two device types with the same name from different manufacturers), we're filtering devices by the device_type_id which is unambiguous.
