You also have options to use MQTT if you want to make sure a message gets through. But that requires an internet connection.

What about without line of sight? If I get one of these is it going to work while it’s sitting on my desk, or am I going to have to mount some antennas on the roof to actually make it usable? The maps only show like three other people in my city with one, so I’m not sure how useful this will actually be for me.

Honestly, its a fun side project, but without enough nodes its more of a hobby. If you want to make it usable, its probably better to use internet or higher power devices (like ham). Or buy a metric ton of these and throw them up high.
As long as you have a node in sight, it should be good for at least some communication. My little window node gets 20+ nodes.
