@rlithgow1: Tempest was doing a beta a while back to find people to mount special sensors on their houses for lightning, you are not mistaken about it. But they can get a couple to cover a pretty wide region. The pulses are pretty easily detectable and just a few sensors can triangulate them for a pretty large area. I volunteered but never heard back unfortunately.
@FiveNines: As for one of the prior questions, there is/are community drivers that support the Ecowitt Gateway (I use the slightly older version, the GW1000). You can find them from the Community Driver list (Custom Device Drivers [Wiki] - #163 by yracine66). For example, my Ambient/Ecowitt driver is on there (since someone mentioned my Tempest driver before).
My experience for lightning detection has been that it is "OK". I have both an Ecowitt Lightning sensor AND the Tempest... We had some in the area yesterday apparently. The results were:
Ecowitt = Fri Apr 21 23:50:46 EDT 2023 & 12.0 miles distance
Tempest = Fri Apr 21 23:52:02 EDT 2023 & 8.7 miles distance
I missed it so I have no idea which was closer on time. But I do not have any array or anything I need to worry about lightning for so it has always been an "interesting" but extraneous thing for me.
