Endless "Out of frame flow!" warnings setting up Z-Wave integration

Configuration Z-Wave
,
1

While migrating my custom installed Home Assistant from Raspbian Stretch on a Raspberry Pi 3 to Hassio on a Raspberry Pi 4 I have difficulties setting up Z-Wave on the hassio installation.

The Z-Wave integration is with endless WARNING: Out of frame flow! (0xc0). Sending NAK. warnings.

...repeat ad nauseam.

The Z-Wave integration has been added through the “Integrations” configuration in the UI. No changes have been made to the config files.

This is on a 2MB Raspberry Pi 4 with an Aeotech Z-Stick Gen 5. hassio version 0.109.6.

Can anyone assist with this issue?

Usually this is because you installed Raspbian first, then the alternative installer, and left ModemManager installed and running.

3

This is a fresh installation done by flashing a SD card with the hassos_rpi4-3.13.img.gz image. Raspbian was installed on a different computer.

4

Are you also using an unpowered USB 2.0 hub inbetween the Aotec and RPi? Alerts | Home Assistant Alerts

I was not aware of this issue. Connecting the Z-Stick via an USB hub has the same result so that does not solve this issue.

6

Double checked this one. ModemManger is not installed on the hassio server, so this is not the problem.

7

Did you install any other zwave addons?
This issue can occur if something else is attempting to use the stick at the same time, ie: ozwcp

8

No other Z-Wave addons. The installed addons are:

  • File editor
  • TellStick
  • Terminal & SSH
  • deCONZ
9

Are you sure the USB hub you used is USB 2.0?
If that doesn’t work you’ll need a new Z-stick or go back to the Pi3.

10

Yes. I reckon my best option is to use a Raspberry Pi 3.

11

At this point in time, it would seem that way.

12

The only other thing I could think of would be an inadequate power supply.

13

Original Raspberry PI USB-C so that is not the issue.

14

I can confirm that this issue is due to Aeotech Z-Sticks and Raspberry PI 4s not being compatible.
I switched to a Raspberry Pi 3 and then all was hunky dory with the same configuration.

This appeared to be a red herring

15

Z-Wave worked on the Rpi 3 on first install, but after rebooting the Rpi 3 the same problem as with the Rpi 4 occurred there as well.

The Z-Stick works on my Home Assistant installation on Raspbian, so the Z-Stick seems to be OK.

Any ideas?

16

You have something installed that’s also attempting to access the stick at the same time.

17

Not likely. These are clean installs of hassio, installed from the official images.

18

So this image?
https://github.com/home-assistant/operating-system/releases/download/3.13/hassos_rpi3-3.13.img.gz

19

Used that when trying to get this to work on a Rpi3 and https://github.com/home-assistant/operating-system/releases/download/3.13/hassos_rpi4-3.13.img.gz for the first attempt to get it to work with a Rpi 4. Same results with both.

The only thing left would be something potentially wrong with the stick itself then.

There a tool you can use with windows and plug the stick into a windows machine to backup the devices, it’s been mentioned a few times on the forum. Maybe it has some kind of diagnostics suite that could be ran on the stick :man_shrugging:
