I have exactly one real use case for LR: I want a contact sensor on my mailbox to indicate when mail has been delivered. Driveway is too long to do that over anything I've got right now, I think.
That said, I wish LR allowed for islands, where an LR device could relay for regular Z-wave devices near it over a long hop.
So right now, Z-wave is mesh. Using multiple Z-wave controllers is usually worse since you split the mesh and that's almost always worse. With LR on everything, or even most things, the notion of using a second or third Z-wave controller becomes much more reasonable. Tho considering the range on LR, you could probably just use a single hub anyway, since it'll work up to a mile over open air.
But I wouldn't be surprised if maybe 900 series adds just that feature you're wanting. It would be a nice feature, and I'm not sure what other 'big new thing' they can add in 900 series to stay competitive.
My point is that most networks will have a few LR devices and mostly mesh devices. If LR devices also repeated from their non-LR neighbors, they could be the beachhead that lets the hub talk to a distant enclave of devices it otherwise wouldn't reach.
That was my case too, until I got a C8 with the external antennas. Z-wave has farther range. Replaced the three spotty, at best, zigbee devices at the end of the driveway with Z-wave. Much more reliable.
anxiously waiting so i can get this device and finally get reliability at the mail box.. right now every month or two i need to replace the 2450 battery in the zigbee smarthings 4 sensor due to the distance and difficulty in signal
I know there are advantages to using newer Z-Wave chips like the 800 series, even without Long Range. But If you already have (battery operated) 800 series Z-wave devices not configured as Long Range, but that are already connected "direct" to your HE, is there any advantage to using Z-Wave Long Range?
I guess I am asking if the "Long Range" adds any benefit other than the long range? Less battery usage? More reliability? More speed?
The way the modulation and radio work on LR it can lead to lower transmission power required, which would equal lower battery usage. But it is 100% application dependent.
No guarantee it would be lower, and no "rule of thumb" to say it would always be lower either.
I'll do similar power testing as shown below on some of the Zooz 800LR battery operated devices once LR is officially released on Hubitat. But even then the results will still be application dependent, but may be interesting to see anyway.
