it is not a question of money but the pleasure to do it is even and to evolve.

I am attaching a diagram of the mysensor part of my installation.
At the moment, I have the cellar's ethernet gateway working.
The usb gateway also works but only towards the 4relais card which controls my 3D printer, The card which controls the mechanical ventilation of the ground floor no longer works.
If I remove the cellar gateway The card that controls the mechanical ventilation of the ground floor works again.

I think that now it works

have followed your advice the two gateways are working properly together. I leave several days in the test to see if it holds up over time.
I thank you for your help because alone I could not find the solution.

I may have found a solution to my problem, I have to test a few days to be sure.
Hard my domoticz installation I have two raspberry one in server the second in client.
The raspberry server is connected to the USB gateway and on the second I have configured the ethernet gateway.
I keep you informed if I still have crashes.

@mfalkvidd Hello,

After a test period, I still have crashes when both gateways are in use.
The catwalks function correctly only if there is only one working.
I made the changes you told me, there was an improvement but after a few days there were crashes again.
is there a tutorial that explains how to make two gateways work on the same network.
I did some research and I can not find any tutorial on this subject.

Thank you for your help

Thanks for your help, I'll do the test tomorrow.
I make this modification in the gateway and in the relay card assigned to it

I am using a USB gateway for the sensors that are in the house. I have an outhouse far from home with an ethernet network. In this dependency I have sensors that are too far away for USB gateway.
It is for this reason that I need this Ethernet gateway.
Hopefully the GOOGLE translation of this post is understandable.
Thanks again for your help.

@mfalkvidd
Sorry but I do not understand...
Are you talking about the radio frequency of the NRF24L01?
Could you give me a tutorial to use different frequencies.
thank you

Thank you for your help, because it is beyond my knowledge.

I use this NRF24L01 radio

I did not know that it was necessary to use different frequencies, I did not change anything, I used the Mysensors file without modification.

Hello,

I have a little problem with my two Gateway my sensors.
I have a USB Gateway and an Ethernet Gateway.
The two Gateways work very well individually.
When I have the two gateways in operation, there is always one of the two which is blocked and no longer communicates with Domoticz.
I am not familiar with knots in Mysensor, and I think there is a problem with the knots.
If you can help me find the solution.

I think you're right and it has a dialogue with a very specific protocol, but maybe my injector is too sophisticated, and a simple injector like the one in the photo does not support a dialog protocol.
