domoticz auto add device (mysensors) even if disable "Accept new Hardware Devices"

[Reza]

@tbowmo
one more question
if we want , the node after add to one controller , node lock ! and dont add to other controller. this is related to controller or our sketch ?
so my neighbor can not add my device

If your neighbor knows your network frequency / network address, he can potentially add your nodes to his network. That is why signing is there for sensitive nodes, like locks etc.

1.so with signing this problem can resolved? i use a signing for my WSN and i told to my neighbor that use a signing for his WSN . Will solve it?
2.also suppose a thief come near my home door , and he has a domoticz with a mysensors gateway ! so if i use a mysensors relay (signing) for electric door lock , he can add my relay to his controller and open my home door ?

please first told me about 1 , and about 2

@Reza Read the documentation please. https://www.mysensors.org/about/signing

@Anticimex
thank you and just one question :) i'm sorry.
how to change frequency for my gateway and my sensors and devices?

[Anticimex]

@Reza I don't know. Signing does not care about frequencies. But a good guess would be to check in MyConfig.h as has already been suggested in this thread. Or search the codebase for "frequency" perhaps.
We are not a living dictionary, you have to expect to do some searching yourself when you work with a project that is "DIY". The slogan for the entire site/community says it all: "IOT+DIY=MySensors".

@Anticimex
in domoticz forum told me to "You should separate these two networks by using different frequency" so i want test this for Separation my WSN with neighbor WSN

thank you my friend for help

If I'm reading the domoticz codebase correctly there is two problems:

1. It will add the node in MySensors node/child listing even if the "Accept new hardware device" flag is disabled. But it wont create domoticz core/ui/..-devices from those.
2. I_INCLUSION_MODE message is not supported by domoticz.

@Reza can you update title of this topic also :)

@pjr
my friend you are presence in all of forum :) :) :)
i change also this title topic for you :)
about domoticz forum i dont understand you mean (The last line )
but generally , i have a network with Rpi (serial gateway) and my neighbor build also a network with Rpi (serial gateway) recently. but after the time , i noticed his devices added in my controller in devices panel ! so for check this issue i setup domoticz with windows (with a serial gateway) so i see devices added auto . . .
you told me device are just in "setup->hardware->mysensors setup" but this is not true . after some refresh web and some push button "learn light/switch" without push reset button on devices !! ( please note without push reset button on sensors) devices are added in "setup->devices" !!!

now i use 2 frequency for gateway (my Rpi and windows) and this is work true and thank you for this <3 i change my all device frequency and i think solved problem between i and my neighbor . this is easy more for me (beginner) . i can not change codes of domoticz . but now i am trying to learn signing (this is hard for me also :) )
but i think signing is not useful ! until that domoticz have this bug , the theif just need my frequency for add and control my device ! so i must dont use my sensors(relay) for door lock and security!!

in the end very thank you for help "using different frequency"

[Anticimex]

@Reza if your lock node require signing, nobody but you can use it. That is the whole point with signing. It does not matter if anyone else tries to send data to it. If it is not properly signed the node will ignore it. I suggest you read the docs on signing carefully (yes read ALL of it). It gives all you need to get going with signing.

thank you very very much my dear @Anticimex for help me .
signing is a complicated issue for me but i am trying for learn this. . .
thank you again

No the "domoticz bug" is not a problem since it dont affect your sensor network or the way theif can use your mysensors network.
Domoticz doesnt have anything to do with signing or encrypting. Its just listening and sending readable serial messages to your gateway.

With signing you make thief not able to use(send messages to) your doorlock.
With encryption you make it almost impossible for the thief read RF messages your nodes/gw are transmitting.

There is good reading for you:

thank you, i am trying to learn signing for use :)
