Describe the issue

What is happening?
I can’t see any neighbors for any of my devices in the Z-Wave network. This feature was working fine a couple of upgrades ago, if I’m not mistaken.
However, my Z-Wave network itself is functioning normally. When I manually update the neighbors for each device, the list populates correctly—but after restarting Z-Wave JS, all neighbor lists revert back to “none.”

What did you expect to happen instead?

Steps to reproduce the behavior:

1. Go to '...'
2. Click on '...'
3. Scroll down to '...'
4. See error

Anything else we should know?

@robertsLando this is why the network map was querying all the neighbors when rendered.
I guess we should do it for a single node when opening the more info popup.

Yep 👍🏼

[zwolfpack]

Hello, I've been meaning to post about this.

Also, "Debug Info" neighbor entries are empty. It's populated once the node map "Discover" button is used. (the controller node doesn't have the Discover button; don't know how to populate that).

[zwolfpack]

The network map mouseover displays shows 'None' as well.

[robertsLando]

11.5.0 vshould fix this

[03397]

It did not. I have upgraded but no neighbors are displayed.

[zwolfpack]

It works partially.

• On the node map, a node's neighbor list is now populated upon open of it's detail view -- except for the controller. That continues to show 'None'.
• On network map, mouseovers show 'None' until the detail view is opened.
• On control panel, a node's "Debug Info" neighbor entries are empty until the network map detail view for that node is opened.

[robertsLando]

yeah I added the fetch only when the details is open for now

[03397]

My bad. I can see the neighbors under each node as my initial picture. But I confirm of what @zwolfpack is saying above.

[zwolfpack]

As of 11.6.1, node neighbors populate once the details view is opened -- except for the controller node. I can't get that one to populate.

Hi,

Sorry for coming back to this after such a long time, i just moved all my zwave network to Zwave JS UI using a ZWA2 controller.

I spent a long time discovering neighbors for all my nodes, the nodes dump export was looking great. But coming back today i see that all the nodes have no neighbors. Opening the detailed view of a node in the network graph does make an API call and the neighbors show again for that node.
To make them show for another node i have to exit the network graph view, re-enter and click another node. Doing that for 130 nodes is not productive, to say the least.

The network itself seems to work fine.

So my questions are

1. Where is the neighbors list actually stored ? i assumed it should be in the nodes dump but its not.
2. Are those API calls that the Network Graph details page is making actual zwave traffic or just an interogation of some file ?
3. Is there a way to actually repopulate all the nodes so that the nodes dump actually shows all the neighbors from all nodes ? And consequently the debug info for each node shows the neighbors.

Thank you !!

[robertsLando]

Giving that neighbors don't tell much about your network reliability them are fetched only on request and cached, I don't understand why you would need to export all node neighbors while the actual map is created using nodes LWR and NLWR and priority routes and tells you how exactly packets are routed in your network something that neighbors will never tell you

[MomosX]

Thats a very good question. i went down the rabbit hole mainly because the list was not populated. After migrating all my network to the new adaptor (ZWA2) i thought it would be wise to manually refresh all the neighbors from each node. After doing that i was surprised to see that info is no longer there - as far as i know - please correct me if i'm wrong - , if a node does not have neighbors it will make a network wide call to find a route - and that willl just overload the network.
I'm trying to reduce the number of jammed instances of the controller...
On another note, the jams might be also directly related to old non zwave plus devices, which i have about 30 - as those make a lot of network wide calls. - this i remember from some years back when investigating slow zwave with a zniffer
On further analisys it seems that the controller gets jammed whenever a node route fails and it has to get another route. 2-3 seconds until it recovers. happens on zwave plus devices also.

[robertsLando]

I tag @AlCalzone for a better answer but I'm pretty sure that as long as you see the LWR that (or NLWR/priority route if speecified) will be the route that the packets will follow so you shouldn't worry

[MomosX]

As i did not want to leave it as is... i made a script that i can run in Chrome console, while having the Network graph page opened.

The script will:

• auto-load all node IDs using getNodes
• skip node 1 (controller)
• calls getNodeNeighbors for every other node
• waits 2 second between calls

The result: all the nodes will have the neighbors list repopulated, even on mouse over and the Nodes Dump Export will contain them too.

No idea if this is the right way , i hope there is a better way - i see no reason why not to show those neighbors, maybe a dev would share some light for a newbie like me.

Here is the script if anyone needs it:

(async () => {
  const delayMs = 2000;
  const skipNodeIds = new Set([1]);
  const socketIoUrl = '/socket.io/socket.io.js';

  function sleep(ms) {
    return new Promise(resolve => setTimeout(resolve, ms));
  }

  async function ensureSocketIoLoaded() {
    if (typeof window.io === 'function') return;
    await new Promise((resolve, reject) => {
      const s = document.createElement('script');
      s.src = socketIoUrl;
      s.onload = resolve;
      s.onerror = () => reject(new Error(`Failed to load ${socketIoUrl}`));
      document.head.appendChild(s);
    });
    if (typeof window.io !== 'function') {
      throw new Error('socket.io client did not load');
    }
  }

  async function openSocket() {
    await ensureSocketIoLoaded();

    return await new Promise((resolve, reject) => {
      const sock = io({
        transports: ['websocket']
      });

      const timeout = setTimeout(() => {
        try { sock.disconnect(); } catch {}
        reject(new Error('Socket connect timeout'));
      }, 10000);

      sock.on('connect', () => {
        clearTimeout(timeout);
        console.log('Socket connected:', sock.id);
        resolve(sock);
      });

      sock.on('connect_error', (e) => {
        clearTimeout(timeout);
        reject(new Error(`Socket connect_error: ${e.message}`));
      });
    });
  }

  function callZwApi(sock, api, args = []) {
    return new Promise((resolve) => {
      sock.emit('ZWAVE_API', { api, args }, (resp) => resolve(resp));
    });
  }

  async function getAllNodeIds(sock) {
    const resp = await callZwApi(sock, 'getNodes', []);
    if (!resp?.success || !Array.isArray(resp?.result)) {
      throw new Error(`getNodes failed or returned unexpected shape: ${JSON.stringify(resp)}`);
    }

    const ids = resp.result
      .map(n => Number(n?.id))
      .filter(n => Number.isInteger(n) && n > 0 && !skipNodeIds.has(n))
      .sort((a, b) => a - b);

    if (!ids.length) {
      throw new Error('getNodes returned no usable node IDs');
    }

    return ids;
  }

  async function warmNodeNeighbors(sock, nodeId) {
    const resp = await callZwApi(sock, 'getNodeNeighbors', [nodeId]);
    return {
      nodeId,
      success: !!resp?.success,
      neighborCount: Array.isArray(resp?.result) ? resp.result.length : 0
    };
  }

  let sock;
  const results = [];

  try {
    sock = await openSocket();

    const nodeIds = await getAllNodeIds(sock);
    console.log(`Loaded ${nodeIds.length} node IDs from getNodes (controller skipped).`);

    for (let i = 0; i < nodeIds.length; i++) {
      const nodeId = nodeIds[i];
      console.log(`[${i + 1}/${nodeIds.length}] warming neighbors for node ${nodeId}...`);

      const result = await warmNodeNeighbors(sock, nodeId);
      results.push(result);

      console.log(
        `[${i + 1}/${nodeIds.length}] node ${nodeId}: success=${result.success}, neighbors=${result.neighborCount}`
      );

      if (i < nodeIds.length - 1) {
        await sleep(delayMs);
      }
    }

    window.neighborWarmResults = results;
    console.table(results);
    console.log('Done. Neighbor data should now be populated for export.');
  } catch (err) {
    console.error('Neighbor warm-up failed:', err);
  } finally {
    try {
      if (sock) {
        sock.disconnect();
        console.log('Socket disconnected');
      }
    } catch {}
  }
})();
