I’ve had mixed signal quality results with an old, cheap, three-foot USB extender cable attached to my Home Assistant Yellow box. I attached a 16-foot Monoprice “USB 2.0 Active Extension / Repeater” cable to my box and put my Zooz ZST39 LR stick on the end so I could reposition the stick.
Upon restarting the HA Yellow box, the blue light on the stick came on, so there was a physical connection. However, for the Z-Wave integration, HA Core 2024.11.3 kept saying, Failed setup, will retry: Failed to connect: Cannot connect to host aod7b954-zwavejs2mqtt:3000 ssl:default [Connect call failed ('172.30.33.0', 3000)]
.
I went to System -> Hardware -> All Hardware
and searched through the hardware devices, but no Z-Wave devices were there.
I reattached my original cable and restarted the box. All was fine.
Why would an active cable cause a problem, even though there seemed to be a physical connection? Can anyone recommend a cable that’s at least 10 feet that does not cause a problem?
Thank you!
