change node configuration via mqtt

[hestiap]

Hi,
that's probably already present in the Discussions, but I could not find something I could use, because I'm a beginner with mqtt :-(
I'd like to modify a value in the configuration of a node
[95-112-0-72] to 6 for example
I've found something like
{ "args": [ "const {ConfigurationCCSet} = this.require('zwave-js');const cc = new ConfigurationCCSet(driver, {nodeId: [95], parameter: 72, value: 6, valueSize: 1}); await driver.sendCommand(cc);" ] }
But I couldn't figure out how to use it.
I've found this
`Topic

<mqtt_prefix>/EVENTS/ZWAVE_GATEWAY-<mqtt_name>/<driver|node|controller>/<event_name>

Payload

{
"data": [ ...eventArgs ] // an array containing all args in order
}`
But with no example, that's not very clear for me...
Do you have an example? or could you give me some hint please?

@robertsLando I think this refers to your documentation :)

[robertsLando]

@hestiap You are actually using a driver function but why don't simply use a normal set value?

https://zwave-js.github.io/zwavejs2mqtt/#/guide/mqtt?id=set-values

[hestiap]

I didn't know it could do it as it is a configuration modification
I'll try in this way, but I'd like to have a complete example as I'm also beginner with mqtt

[hestiap]

I've tried this
mosquitto_pub -t zwave/nodeID_95/112/0/72/set -m "{"value": 6}"``
and got this

No change in the value :-(

Could you check logs to see if the backend receives the set request? You should see something like Write request received ...

[hestiap]

Yes!
2021-11-15 20:09:51.319 INFO MQTT: Message received on zwave/nodeID_95/112/0/72/set: '{value: 6}'

[robertsLando]

@hestiap Ok that log should follow a write request log, if not means that for some reason there was no listener for that specific value. Also what z2m version are you running?

[hestiap]

@robertsLando
it was not the exact node in the message...
with this message mosquitto_pub -t zwave/95/112/0/72/set -m 8 it is OK now
Thanks for your help

You welcome :)
