This sounds like a great technique. If you wanted to modify it this way, I’d love to incorporate your contribution!
Hello
I just tried to follow above for the z-wave graph and in particular this post:
I have the .js file in /config/www/ but when clicking the zwave graph panlen that showed up on the GUI it is just nothing there.
Also in the log i get messages like this
2020-10-18 15:57:22 ERROR (MainThread) [frontend.js.latest.202010012] https://192.168.1.89:8123/local/zwavegraph3.js:6:1 Uncaught SyntaxError: Unexpected token ‘<’
Suggestions are more than welcome 
I am facing the same problem… HA version 0.116.2
Are getting the same error message?
I under stand that the error is referenced somewhere in this post above but I cant find it… google points to it but I don’t know how to search these huge threads 
Tried that but could not find any hits in my duckduck search 
Anyway, reinstalled the .js and now itworkd´s fine!
Getting the same error here. Deleted the .js and config, restarted, reinstalled. same same…
2020-11-03 01:22:40 ERROR (MainThread) [frontend.js.latest.202010214] http://192.168.1.25:8123/local/zwavegraph3.js:6:1 Uncaught SyntaxError: Unexpected token ‘<’
Where is the value “not connected” based on? I have two devices that according to the Z-Wave Graph are not connected but work fine regardless. One is a AC switch.
Looking at the properties of the device I see no reason for it to classify as unconnected.
Getting the Unexpected token error as well. Tried to remove, reinstall, and reboot but had no luck.
Error:
Logger: frontend.js.latest.202011112

I had this same error and it was due to having the file in a sub directory of the root directory, once I moved it to the root directory the error went away and it started working.
So, you just moved it to the root of the config folder? Did you have to change anything in the configuration.yaml file?
I moved it to www also know as local folder. This is what my config looks like
panel_custom:
- name: zwave-graph-panel
sidebar_title: Z-Wave Graph
sidebar_icon: mdi:access-point-network
module_url: /local/zwavegraph3.js
config:
ranker: network-simplex
edge_visibility: relevant
grouping: z-wave
Ahh, yeah that’s where I have it and the yaml matches. Still getting the error.
this happens if you download the webpage that displays the code on github vs the actual .js file.
ie if you just used wget to pull the file onto your ha appliance try using something like:
wget https://raw.githubusercontent.com/AdamNaj/ZWaveGraphHA/master/zwavegraph3.js
That worked. Thank you!!!
