Ordered a KLF 200, paired all 14 in an afternoon (the “add product” step from each keypad is fiddly, you have to hold it right up close). pyvlx sees them, positions arrive in Hermetry as win01.pos to win14.pos and the rain contact closes everything in about 40 s. Had to update the box firmware first exactly as you said, out of the box it refused the connection. Cheers.
