Dual node Meshtastic and MeshCore. I think both networks have their benefits, and now I don't have to choose. We'll see how two nodes does in the winter. But right now a single solar panel is plenty to keep the battery constantly topped up.
Yes, as mentioned in another comment, I understand the impact. The mesh traffic in my area is extremely light, and I expect cross node interference to be extremely rare. But, it's something I plan to address in the next version.
