I have a mix of 700 and 800 series Z-wave gear, and I find it borderline useless — a mesh hop struggles to reach one room over. LR is a rather different thing — slightly different frequency, very different topology, and it requires explicit controller software support. As far as I can tell, most or all 800 series hardware supports LR, 700 might with appropriate firmware, and earlier chips do not. node-zwave-js does not yet support LR, but someone seems to be working on it (slowly).
