noticed things getting triggered randomly for no reason, narrowed it down to Zooz USB conrtoller losing connection. anyone can help troubleshooting this? ZST39 LR on Rpi4 which is on Ethernet.
#z-wave intermittantly resets

check logs for errors

#1284966617670881350 with the "Z-Wave" tag might be able to help.
Oh. freshcoast already joined in.
deft charm
Still, a good suggestion. 😆

looked at the raw log there is a flood of messages about not being able to read another device that is on wifi, I need to take that out to clean up the log. but did not find anything about why the zwave went offline.
deft charm
There will be logs about it disconnecting. Also check the z-wave js logs.

Home Assistant Core logs is flooded with errors, of many devices. looks like my z-wave controller is also going out. maybe the Rpi is dying?

I just found an enabled Debug logging on z-wave, still trying to figure out where to find the logs

maybe not directly related to this issue, but might check power supply of pi is still ok (not to hot) and if you are running from sd card for a while, it can (and will) corrupt over time. Powered usb-hub with ssd would work better.
vocal bronze
yes, was just looking at the Rpi, seems ok, I shut it down and moved Zwave controller to different port and moved Rpi a little in closet, might need to move it to diffent location. Doesn't explain why it started in past week or two.
wonder if I can ssh in and run HTOP to see Rpi's temperature

addition: use extension cable for dongle>interference and if possible, use a powered usb-hub to connect dongles on USB2.0 port
vocal bronze
ah good idea
carmine scarab
over and out 😉 sorry hijacking this thread
one more..lol if you set-up your dongle and you get asked what port/device, try to use by-device-id instead of port
vocal bronze
I appreciate anything that I can learn from. np
also, I have dongle pointing straight up, maybe I should put it horizontal?
carmine scarab
as far as i know its multi-directional, so that would matter that much. Can be wrong though lol

You might be able to eek out a few more dBm for background RSSI by tweaking the position, but currently it's "good enough". I don't think it's a contributor to your connection problems.
2025-11-12 10:25:41.617 DRIVER « [RES] [GetBackgroundRSSI]
channel 0: -98 dBm
channel 1: -100 dBm
channel 2: -100 dBm
channel 3: -94 dBm
Ideally 800-series would be closer to -110 dBm for channels 0-3.
The log attached earlier doesn't show any problem, it's mostly just idle.
The timeout problems at the beginning aren't in Debug level, so hard to tell what's going on there.
Whatever node 4 is seems to be having some trouble.
vocal bronze
the logs are quiet now since I reset and moved it. So I hope that was it.
deft charm
What firmware version is your controller on?
deft charm
Oh here's where it disconnected:

How'd you get the log file? From the add-on page?
vocal bronze
settings > system > logs , then I saw drop option in upper right
deft charm
Is there anything in the home assistant log file around 08:57:50.468?
You have to look in the "raw" logs, not just the UI summary
Or download them
vocal bronze
looking... got file downloaded
I downloaded the most lines I could , time stamp been purged already, so many lines after that time.
deft charm
Strange, I don't see anything about HA losing connection to the add-on during those times.
vocal bronze
seems all ok now, maybe...
