Meshtastic maps and viewing connected tracking devices

[LCuinu]

I'm UK based and a home gateway feeding mqtt into Home Assistant. The main aim is safety tracking in the mountains. All the tracking devices will feed position/battery etc into mqtt. I'm thinking of bridging the mqtt to one of the meshmaps (either Liam Cottles or the default) but I wondering which is better (if any) of viewing the trackers that are connected in my mesh? I tried Liam's and got the gateway to show on the map but not the test tracker (even though it showed I had 'x' amount of connected devices. I'm aware of publicly showing this but they are purely safety with any messages being safety related.
