Multicast Failures

[Botched1]

I originally posted this in the other thread, but my issue sounds like it may be different than his so I thought I would start my own thread.

I'm using a ZST39 running 7.22.1 and see multicast commands fail somewhat regularly. If I repeatedly send multicast commands I can get it to give the error maybe 3 out of 10 times or so...

I'm running:
zwave-js-ui: 9.20.0
zwave-js: 13.3.1

Integrated to home assistant via the web socket route (not MQTT).

What I see in the logs when it fails:

2024-09-25 20:30:38.430 ERROR Z-WAVE-SERVER: The node did not acknowledge the command (ZW0204)

In my case I send the command from node-red to Home Assistant. It is configured as follows to turn a group of 4 switches off:

command: zwave_js.multicast_set_value

{
    "entity_id": [
        "switch.parlor_front_left_light",
        "switch.parlor_front_right_light",
        "switch.parlor_rear_left_light",
        "switch.parlor_rear_right_light"
    ],
    "command_class": 37,
    "endpoint": 0,
    "property": "targetValue",
    "property_key": 1,
    "value": false
}

Please make a driver log showing the issue, loglevel debug and attach it here as a file (drag & drop into the text field).

Here is what I learned...

The last multicast command that issued an error was at 18:22:49.

• I don't see any obvious errors or issues in the driver log (attached).
• I do see an error just like the one in the OP in the DEBUG log as viewed in the zwavejs ui.

Yep, I'm an idiot.

I'll get the right log this evening. Sorry about that.

[Botched1]

That's not a driver log. That's the application log.

Here you go. Failure is at 2024-09-27T12:33:26.205Z

Hm that looks an awful lot like the issue in the other thread.

[AlCalzone]

Let's continue over there.

[Botched1]

Ah, maybe it is the same thing then.

I've tried rebuilding the routes to the 4 devices, no change. I'll go look over in that other thread and see if there are other things I should try.

I do have a UZB3 flashed as a zniffer, but it isn't hooked up. I can try to do that this weekend.

[AlCalzone]

You can do that. I'll see if I can reproduce myself, and report all findings to Silabs.
