A crude version of Mach Band 2 / Revision 2 was deployed early February 2025. It now contains not just one sensor but two, one for up street and one for down street.
Revision 1 was point to point bluetooth but now Revision 2 introduces BLUETOOTH MESH.
From point to point to mesh
Bluetooth mesh contains many advantages such as much better communication between nodes, range extension, redundancy, ease of adding and subtracting nodes.
