KeviNH Posted January 7, 2022 Posted January 7, 2022 (edited) Having Z-wave mesh issues at my non-profit, looking for the best bang for our buck -- do we buy two older "Range Extenders" or wait for a backordered Aeotec RE7 to finally ship? Does the claimed greater range/power of the Aeotec 700 extender apply in an ISY994 network with mostly older Z-wave devices? Currently best priced in-stock plug-in z-wave device is the "Ring Alarm Range Extender (2nd Gen)", is this what we should go with rather than spend +$30 on a smart plug that is going somewhere we'll never use the plug part? Normally I'd go with hardwired power on motion sensors, but those also are tough to find in stock and also expensive (see "non-profit" in first sentence) Edited January 7, 2022 by KeviNH
lilyoyo1 Posted January 7, 2022 Posted January 7, 2022 Yes and no. Aeotech range extenders do amplify the signal as well so you'll get that benefit. However, it will match whatever the lowest series your devices are
KeviNH Posted January 7, 2022 Author Posted January 7, 2022 So the answer to "Does the claimed greater range/power of the Aeotec 700 extender apply in an ISY994 network with mostly older Z-wave devices?" would be "No"?
lilyoyo1 Posted January 7, 2022 Posted January 7, 2022 (edited) As answered many times on these forums it's No. However the amplification could potentially help your system Edited January 7, 2022 by lilyoyo1
KeviNH Posted January 8, 2022 Author Posted January 8, 2022 Barring somebody getting the straight dope from Aeotec or Silicon Labs, I'm not sure that "No" really is the answer. For example, regarding "the amplification could potentially help your system", I suspect that if I swap out my old repeaters for Range Extender 7, then I should be able to have a greater distance for the hops that go from one 700 extender to a second 700 device. Only way to be sure is to test it, or to get Aeotec or Silicon Labs to respond to my question...

It's already been well established as fact that zwave send signals at the lowest common denominator.
dbwarner5 Posted January 9, 2022 Posted January 9, 2022 Am not that familiar with zwave but do have about 10 devices (locks, thermostats, outlets and plug-warts) in my ISY, but with Insteon's potential demise, I have been looking at some replacement / new z-wave devices. If my zwave mesh operates at the lowest common denominator in terms of speed, is there a way to tell what speed / series, each device is via the ISY? Or another way? Both out of curiosity but also to potential replace older. slower ones if they are the bottleneck. thanks.

Realistically, given the small packet size of Z-wave commands, "speed" is not really a significant concern -- even the fastest 700 devices only move data at 0.1 mbit/s (still ten times faster than the original 100 chipset) The biggest bottleneck and the greatest influence on range, reliability, and battery life is going to be the chipset of your controller. Quote is there a way to tell what speed / series, each device is via the ISY? Or another way? That's a good question. I suppose you could physically go to each device and write down the FCC ID.

If you have the 300 board then it doesn't matter the devices. Everything will operate at 300 level. If you have the 500 board, I'd look at when you purchased your devices. Anything you bought in the last few years increases the likelihood of being zwave plus. Zwave doesn't pick and choose based on device series so any older devices will affect your system.
