This will allow you to configure environment parameters for this and only this device, and which will be appropriately inserted into this device's "local_conf.json" with lowercase tuple names derived from the appropriate uppercase environment names beginning with "GW_".  For example, for an IMST gateway with no GPS, the MINIMUM environment variables that you should configure at this screen should look something like this.  For the LinkLabs gateway, which has a built-in GPS, you only need REGION, CONTACT_EMAIL, and DESCRIPTION.
