Is there a menu item that I cannot find that allows me to monitor internet traffic to/from my C4 hub? I'm trying to debug my home network and this might help me.
Can you elaborate?
not per say on the hub but most home routers have a traffic monitor that lets =you monitor by device.. i know asus do.
No.
You need an external tool for this. Some routers have this facility built-in.
Use an ethernet cable, and hub (not a switch, unless you have a span/mirror port).
Then wiresharek to capture traffic, and filter on specific IPs (hub being one of those).

I'm not getting an image from my security camera into an image virtual device in a dashboard in Hubitat, even though I can use the same URL in a browser on my PC and it works fine. So, what is the difference? Is it because I have my VLANs configured wrong, such that the image is not making it to Hubitat from the camera? Or is there a security issue that the prevents the camera from sending an image to Hubitat? Or do I have a DNS issue since I am running unbound in my router? I'm not aware of a ping utility from Hubitat to see if it can reach the camera as a diagnostic (BTW, if the implementation gods are listening, please add a network diagnostic like ping somewhere in Hubitat), so the only thing I can think to do is try to capture packets and responses from Hubitat to see if the image is being requested properly, then if the camera is responding as it should. Because I have VLANs protecting all devices on all ports, I would need to intercept packets from my managed main switch but then I would need a PC with Wireshark to look at a mirrored port. I may end up doing this, but was hoping there was another easier approach.
I will see if the traffic monitor in my Asus router can help, but I suspect once established, the router is not involved and all that traffic is contained within the main switch, which is why I need to monitor at the switch level.
The hub does have a ping utility. In settings —> network setup —> network test menu.
I do not have a Network setup option in the settings screen.
I have vers 2.4.0.146.
Are you certain? Nothing here? The second screenshot shows where to click to get Ping and other tests.
Try turning on Advanced/Developer options slider at the top of that page? I don't think that networking is supposed to be hidden by that setting, but maybe it is?
Its a C4 hub, it possibly did not have any network settings available so it is hidden in the UI.
Try going to the url directly. http://HUB.IP/hub/networkTest
If the Cam and Hub are on separate VLANs, then yes, probably.
Unlikely, the cam is just hosting a web service, the URL connects to that and grabs it.
Are you calling the cam with a hostname or the IP in the URL? DNS would only be in play if using a hostname. Try using an IP.
Most likely cause of your issues is an overly complicated Home network.

http://HUB.IP/hub/networkTestworked, thanks. That's not exactly an obvious thing to do.
Ping worked, so those packets seem to be traversing the network correctly. That suggests to me that my VLAN config is not necessarily the issue with my image problem. Possibly that menu item is hidden because the Traceroute tool seems to be broken, and Speedtest is trying to get to an invalid address.
VLAN management is all about managing how ports are tagged and untagged, and what ports can talk to what other ports. Maybe I'm overly paranoid, but I do not want any rogue IoT device corrupting any other device on my network.
I am using IP addrs, so your comment about DNS is probably right.
Overall, it seems I still need to Wireshark that connection to see what's going on.
Setting Advanced Options to ON has no effect in that menu.
Do you have any instances of this "image virtual device" working? I would do a baseline test and try to grab a random image from the internet to make sure it is even working at a basic level.
Its hidden because you have a C4 which I think has no networks settings available. So the settings page is hidden, which has the link to the network test page within it. Tagging @gopher.ny
The Traceroute might not work on the C4. The speedtest has been broken for a long time.
Yes other images work. I linked on to a weather forecast image and it displays fine.
On a whim, I tried the Firefox browser and found the camera pics displayed as they should. I had been using Vivaldi, so I was chasing a browser issue. I then tried the Brave, Opera, and Duckduckgo browsers, all based on Chrome, and none worked. Floorp. which is based on FF, does work. So while now I have to find the common setting in the chrome-based browsers that is preventing the image from displaying, at least I know my VLAN-based network and the camera image-capture strings are working.
Update: Edge also does not work, so all the chrome-based browsers are the problem.
Using the chrome-based browsers, I can view the IP camera snapshots in a separate tab of the browsers but not in an image tile in a dashboard. Image tiles appear to only work in Firefox-based browsers. Is this a Hubitat bug?
Interesting. I normally use firefox but I can confirm this is an issue
Here is firefox
ez-dash
classic dash
Here is Edge
