Changing Node Id of Serial Gateway

[Lyubomyr]

Hello.

Can I change Node ID of the Serial gateway? I'm using Domoticz as a controller.
I tried to change the code
gw.begin(incomingMessage, 24, true, 0);
// also tried gw.begin(incomingMessage, 24, true, 24);

and changed each
serial(PSTR("0;0;%d;0;%d; .........
into
serial(PSTR("24;0;%d;0;%d;.............

// also tried cahnging into serial(PSTR("24;24;%d;0;%d;.............

I made changes in the files SerialGateway and SerialGatewayUtil
The node with sensor sees SerialGateway; Domoticz showes log "Serial gateway ready", but Domoticz does not see the sensor.

No, you cannot. May I ask why?

I suppose that this could increase security a little bit. Sorry to hear that this is impossible.

How would it increase security?

[Lyubomyr]

Well, if one wants to steal a signal, it would be more difficult to him to understand what is happening. It is some kind of Security through obscurity.
On the other hand if something wants to pretend being a gateway, it would be more difficult to find out what node id does the node have.
I understand that this not huge security upgrade but this can cause some difficulties for intruder.

This thread might be of interest if you want to increase security: http://forum.mysensors.org/topic/1021/security-introducing-signing-support-to-mysensors

There is also a sniffer available to capture traffic (including node ids): https://www.mysensors.org/controller/sniffer

I've seen the security link, but sniffer is very interesting indeed. Thank You!
