#Cannot see any Z-wave devices on brand new HA instance. Using Zooz ZST39 LR

Hello HA discord. I have been attempting to add z-wave to my HA setup and it is the only thing eluding me to this point.

Goal: To add a Z-wave device to the network.

I have tried two different devices:

  1. 1st Alert ZCOMBO some detector
  2. Aeotec TriSensor 8. (I bought this because I wanted to make sure it wasn't the detector.)

I have a ZST39 LR 800 stick plugged in and running on a bare-metal install of HA OS. I have used the steps on the HA website to setup the Z-wave JS add-on and integration. HA sees my USB device, shows me the model and firmware version (current 1.5) so it seems like that is working. When I go to add a device, I had live logs running and here's what happens when I try to add the Aeotec TriSensor 8.

Try adding an extension cable to the USB stick

I forgot to add I am literally sitting next to the PC and the device is within 2 feet of the stick.

I'll try it now on an extension. Any advice on how long? I have a couple 3" ones and a 6-footer.

#

The stick is on a motherboard USB slot.

Doesn't matter when there's USB interference making your background RSSI terrible

Ooo, thanks.

nothing's going to work at -65 dBm background RSSI

I'll try a few and see if I can get the RSSI better.

-128 would be good, but I have trouble believing it.

Interestingly, moving the stick 6 feet away on an extension had no real effect on the RSSI channel 0: -105 dBm
channel 1: -105 dBm
channel 2: -105 dBm
channel 3: -95 dBm

Better I suppose, but nowhere near nice. I'd think something around the -70 to -40 range would be more ideal. If I am reading currently, the Z-wave devices here in the USA are 900Mhz devices. Only 900mhz device I have is a weather station on the roof.

That had the completely expected effect

#

those are practically ideal values, aside from channel 3

#

as I said, I suspect -128 is not real

#

these are the background RSSI measurements, e.g. the noise floor

#

I just managed to pair a device in this config by placing it literally next to the device.

#

Ok, if that's measuring noise floor, that makes more sense.

#

-65 dBm, which is a strong signal for a device, was indistinguishable from noise

#

I'm getting variateion in that RSSI reading now, whereas I was not before.

#

0x0107013b80bfbf80c2 -> 80 bf bf 80 are the values, so ZJS interpreted it correctly. But it's one off "not available".

#

The lowest sensitivity spec for an 800-series chip is -110.9 dBm. good background RSSI measurements are near those.

This makes much more sense. I had not encountered the info on USB3 ports causing interference prior to your git link. Thank you for that. That must have been my main issue as I have been able to add both devices now.
