Problems with z-wave inclusion, not finding devices

Configuration Z-Wave
1

Added z-wave js ui, finds node and everything looks fine.
But can’t find devices when I search for a thermostat example.
(Smartthing finds the device)

Tried several times to include and exclude and reset the device.

I have Silicon Labs controller 700, with verson v.7.21.5.

I have tried:
-Extension cable

  • USB hub
  • Switched usb 3 to 2 and vice versa
  • Previous firmware on z-wave stick
  • Full documentation to the letter, I think…
    -Checked other forums/problems her and other places
    -Tried regular z-wave integration
    -RF set for Europe
    Norman pow: 9.9dBm
    Mes out pow:
    0dBm
    Port: 3000

Stuck… any suggestions? :slight_smile:

What firmware file did you use to upgrade to 7.21.5?

3

Update Z-Stick 7 with Windows (V7.18.8 → V7.21.5) : Aeotec Help Desk
Download V7.21.5 update (Before installing this version, install 7.18.8 to avoid bricking your Z-Stick 7)

  • All Frequencies
    • Warning - Make sure that you install 7.18 before you update to 7.19 or later to avoid bricking your Z-Stick 7.
    • Repeat these steps again to update to 7.21.5

These are instructions for a Aeotec Z-stick. Do you actually have a Z-stick, or do you have the SiLabs UZB-7 (SLUSB001A)? While they share the same Z-Wave SOC, they are not the same board.

I have Silabs SLUSB001A, but it has the same firmware?

It supports both BRD4206A and BRD4201A firmware. Aeotec uses BRD4206A firmware. In my experience, and a few others, newer versions of the BRD4206A firmware are broken on the UZB7, causing completely reduced TX power which could explain your problem. You might see if flashing the BRD4201A firmware fixes it for you. In EU there’s no reason to use the 4206A firmware anyways as it won’t ever support EU Long Range. https://github.com/kpine/zwave-js-server-docker/wiki/700-series-Controller-Firmware-Updates-(Linux)#silicon-labs-uzb-7-slusb001a

Also, I’m just wondering how you came up with these power values. They are not the default and there are no published values for a UZB7. I don’t think it is critical, just curious.

Thanks for the help, I’ll try it out. I found the power values ​​in one forum, someone else had good experience with those values.

I was able to find the recommended power levels by Aeotec 700 stick:
z-stick 7 power levels

in short:

Best TX Power Levels.
For US Frequency:
TX Power Level Normal = 9.9 dBm (or 99 value)
TX Power Level Measured = -6.5 dBm (or -65 value)
For EU Frequency:
TX Power Level Normal = 9.9 dBm (or 99 value)
TX Power Level Measured = -2.3 dBm (or -23 value)

Can’t say if it’s universal for all, but it clearly improved connection quality for my setup.
