Describe the issue

What is happening?
Sporadically when asked to execute multiple commands at once, ZWave JS throws the following error and fails to update specific nodes:

[setValue] raised ZWaveError (not handled, code Controller_MessageDropped): Failed to send the command after 1 attempts (ZW0202)

The nodes this specific error appears on seems to be sporadic and nonspecific to single nodes

Steps to reproduce the behavior:

1. Fire multiple simultaneous setValue commands
2. Error occurs almost immediately

Anything else we should know?
This issue has popped up after a full network teardown and rebuild to move from a Gen5+ to a ZST39. This problem is difficult to reliably replicate but seems to be related to when I smash the network (sending a turn off command to 22 light switches on the network). I THINK this is probably a "me" problem (or a my network problem.... but the "1 attempts" makes me also wonder if this isnt a bug

Software versions

Z-Wave JS UI: 3.18.0

Home Assistant Z-Wave Integration: Driver: 14.3.7 || Server: 1.40.2

Z-Wave Controller (Stick/Dongle/...)

Zooz ZST39 800 Series LR Zwave Stick

Device information

Usually part of the problem:

Manufacturer: Inovelli
Model name: LZW31-SN
Node ID: [2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15, 16, 17, 19, 20, 21, 26, 28]

Manufacturer: Inovelli
Model name: VZW31-SN
Node ID: [22, 23, 24, 27]

Not usually part of the problem: (because they really arent part of the automations that smash the system)

Manufacturer: Leviton
Model name: ZW4-SF
Node ID: [3]

Manufacturer: Ultrapro
Model name: 39348 / 54890 / 54891 / ZW4008
Node ID: [025]

Manufacturer: Ecolink
Model name: DWZWAVE25
Node ID: [029]

Checklist

• I made sure to provide a driver log on level debug.

• The log includes a re-interview of the problematic device (if applicable).

• The log includes the problematic interaction with the device (if applicable).

• I provided the node ID of the problematic device (if applicable).

I can't see which firmware version you're on. 700 and 800 series have been plagued by a series of issues where the controller fails to send, sometimes sporadically, sometimes when there has been a bit of incoming traffic before.

Sending a command to 22 nodes that also respond is a good way to trigger these issues.

This typically shows up in the logs like the callback just above the log you quoted:

The most recent fix for this has been in SDK 7.23.0, but unfortunately there is no Zooz firmware built with that yet AFAIK.

Side note: your background RSSI also seems very high. For 800 series I'd expect values around -110 dBm.

                                    channel 3: -88 dBm

I also see a bunch of repeated electric measurements on a timed schedule, which can cause additional load/noise in your network.

For both I recommend working through https://zwave-js.github.io/node-zwave-js/#/troubleshooting/first-steps - it might just help with your original problem too.

Zooz is taking a really long time to build a new firmware. :-(
