Payload for "node_value_updated" is huge

[Westcott1]

I'm working on decoding the "node_value_updated" payloads.
They are HUGE, the worst is for a TKB TZ56D dual wall switch at 269984 chars.
Most of that is 255 pairs of scene configuration.

Is there any way to get just the device values? (like zigbee2mqtt)

The log shows what has changed, and publishes a basic message -

Why not just subscribe to single values update? I don't understand what you are trying to archieve here

[Westcott1]

I'm subscribed to "zwave2mqtt/+/+/+/+/+" which seems to get all device updates e.g. "zwave2mqtt/Study/WallSwitch-2/37/0/currentValue".

My goal is to send them to Domoticz.
I already have a single nodejs app that does this for zigbee2mqtt and a Tanmotised Sonoff ZBBridge.
This is an extension to that app.

What about creating a plugin for this? https://zwave-js.github.io/zwavejs2mqtt/#/guide/plugins?id=plugins

[Westcott1]

Thanks, I'll try that route.
There is so much to learn about this project.

@Westcott1 That would be your best choice for that use case. If you wuccessfully build a plugin let me know and I will add it to list of available plugins
