For now, you may just do what I do, and that is to update the position of the station when I arrive at my destination. I have used an iPad and a cellular access point to connect to the internet. The station uses very little data so it hasn’t been an issue for me and my 15GB/mo plan I’m on, even when it has been on for over two weeks. The Tempest is great for the RV since it only requires one siting rather than two like the SKY+AIR requires.
FWIW, I have the public location fixed and only change the actual location which WF uses.
