Multiple responses to MultilevelSwitchCCGet during manual polling

[nmpu]

I have 10 NuTone NWD500Z non-Plus dimmers which I manually poll in HA with service: zwave_js.refresh_value. The polling is approximately once every 5 minutes. Each device is spaced 30 seconds apart. When I look at the Z-Wave logs, I'll occasionally see multiple replies. It's hard to believe any single device would be this aggressive. Could this be multiple neighbors relaying the response? Some of the replies are broadcast (node 255).

This is a connectivity issue. The devices (or repeaters along the route) re-transmit their answers because they didn't get the acknowledgement from the controller. Eventually they even resort to broadcasting.
