Perfect, yup that did the trick.

Thank you

I'm getting this error as well after a failed upgrade. Unable to connect on port 8084.

I've tried creating the file above but it has no effect. Restarted the Pi and will getting the same error.

How do I resolve this error?

Error logs if it helps:

Last error:

[2016-03-05 14:04:57.615] [core] Notification: critical (z-wave): Cannot start Z-Wave binding: Error: Bad data - communication failed

Update: Fixed the issue - reinstalled software. Not sure why it went wonky.
wget -q -O - http://razberry.z-wave.me/install | sudo bash

Would someone please help me with pulling up the page that has the Expert UI settings?
I am having the same problem as others regarding the Webif upgrade... thank you

How do I do this?
Expert UI -> Settings -> Management -> Firmware update -> Update to latest

PoltoS wrote:Please got to Z-Way->Setings->Management->Firmware upgrade. Once you close the popup, webif closes back. his was done for security reasons. You can also enable it using shell (in case of troubles with Z-Way):
/opt/z-way-server/automation/storage/8084AccessTimeout-6b497208061ec7faae003cdd7f9a035e.json

Write time to open 8084 in it (in seconds).

When I enter the above the following is what I get:

pi@raspberrypi:~ $ /opt/z-way-server/automation/storage/8084AccessTimeout-6b497208061ec7faae003cdd7f9a035e.json
bash: /opt/z-way-server/automation/storage/8084AccessTimeout-6b497208061ec7faae003cdd7f9a035e.json: No such file or directory

Would you please let me know what I'm doing wrong?
I am trying to correct the issue with following error:

" Webif is switched off. You can switch it on from Z-Way UI or box shell"

Thank you.[/quote]

It should be

PoltoS;
When I enter the command you sent below; i receive a "Permission denied" error... see below... please let me know what I'm doing wrong... thank you...

pi@raspberrypi echo 900 > /opt/z-way-server/automation/storage/8084AccessTimeout-6b497208061ec7faae003cdd7f9a035e.json

bash: /opt/z-way-server/automation/storage/8084AccessTimeout-6b497208061ec7faae003cdd7f9a035e.json: Permission denied

Did you try with sudo?

Yes, I tried it with psudo as follows ... same results... Permission denied.... see below

pi@raspberrypi:~ $ sudo echo 900 > /opt/z-way-server/automation/storage/8084AccessTimeout-6b497208061ec7faae003cdd7f9a035e.json

bash: /opt/z-way-server/automation/storage/8084AccessTimeout-6b497208061ec7faae003cdd7f9a035e.json: Permission denied

That's really strange, but maybe the permissions got screwed up somehow. Check the permissions:
That should show you that at least the user (root) has +w.
