I just tried creating a Favorites List for MetroSafe with Sentinel. The needed sites and talkgroups are created as they should be. Everything that your scanner is capable of "listening" to on the MetroSafe system is there.
If you are not receiving them, you should confirm the applicable service types are turned on in the scanner.
Attached is the HPE version of that download, in a zipped format. You can unzip and import it in Sentinel as a Favorites List. If you want to set up quick keys, you can (which is advisable).
The MetroSafe System has a mixture of clear and encrypted talkgroups. Many of those encrypted talkgroups have found their way in the database and as such are part of the download in Sentinel. However your scanner is unable to "listen" to them as they use encryption full time.
