Installed with Snap on an RPi4 - now how to start web interface?

[Westcott1]

Hello all,
Just newly discovered jwavejs2mqtt (zw2m) and installed it on my RPi4 using Snap.
Everything seems to have installed OK, and all setup commands apparently respond correctly.

zwavejs2mqtt.help
sudo snap connect zwavejs2mqtt:raw-usb
sudo snap connect zwavejs2mqtt:hardware-observe
sudo snap logs zwavejs2mqt
sudo zwavejs2mqtt.enable

All the above seem to respond correctly.

My question is -
How do I start the web interface on port 8091?
Or is there a config file to set up first?

It's embarrassing - all the rest of you seem to have done it OK!

Hi, have you tried to reach it the http://[ip]:8091?

Can you check the logs after a restart, do: sudo snap restart zwavejs2mqtt && sudo snap logs zwavejs2mqtt -f and look for some errors?

[jmgiaever]

Alternatively, you could disable the daemon first, to make sure everything is running smooth first.

1. disable with sudo zwavejs2mqtt.disable
2. run zwavejs2mqtt so you can follow output/logs sudo zwavejs2mqtt.exec
3. open http://IP:8091/ in your browser. Swap IP with the actual IP of your Pi,

You should now see the logs or potential error messages

Also, are you using Raspbian? See the last snipped in the blue «Note» here

Hi Jmgiaever,

Thanks for all your help.

Hi, have you tried to reach it the http://[ip]:8091?

Yes, it doesn't find anything.
It works OK for Domoticz on :8080 and zigbee2mqtt on :8087

Can you check the logs after a restart, do: sudo snap restart zwavejs2mqtt && sudo snap logs zwavejs2mqtt -f and look for some errors?

I was hoping that I could fix the error in the interface. :)

Alternatively, you could disable the daemon first, to make sure everything is running smooth first.

disable with sudo zwavejs2mqtt.disable

run zwavejs2mqtt so you can follow output/logs sudo zwavejs2mqtt.exec
open http://IP:8091/ in your browser. Swap IP with the actual IP of your Pi,
You should now see the logs or potential error messages

The output is just the same as above, and :8091 does not work

Also, are you using Raspbian? See the last snipped in the blue «Note» here

Yes, I had to run the beautifully detailed fix, and it worked perfectly.

Sorry, forgot to reply in-thread. See my reply below. :)

[jmgiaever]

Try setting host to 0.0.0.0 instead of localhost?

You can do it like this

sudo snap set zwavejs2mqtt server.host=0.0.0.0

[Westcott1]

Yes, that did it!
Thanks.

[jmgiaever]

Great :) Happy to help - and sorry for my late reply. I've been very busy.

[Westcott1]

It looks like I had never used the server.host command at all :(

[jmgiaever]

I understand. Glad you solved it! :)
