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

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.

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 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 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.

Hello,

I realized the gateway W5100, it works perfectly.
  On the Ethernet card 5100 there are two PINS for POE power supply.
I would like to use this power supply to power my gateway using of course a voltage converter to go from 48 volts to 5 volts.
My problem is as follows I have no voltage on the two POE power terminals of the ETHERNET board.
I tested with my POE switch and a POE injector but I still have no voltage.

do you have an idea.

Thank you

DANIEL
Hoping that this post is understandable in English

Thank you for your help I passed the 2.2 satable version
I am now launching on the ethernet gateway.

W5100 Ethernet gateway
Hello,
I want to realize the Ethernet gateway with the ETHERNET W5100 module.
The terminals of my W5100 module are not identical to the ones you have.
Here is the location of my 5100 Ethernet module.

V+5 GND
NSS RST
MO SOK
GND MI
POE- POE+

Could you confirm the correct match?
V + 5 to connect to + 5v
GND to connect to GND
NSS corresponds SS / CS terminal 10 Arduino ???
RST I do not know ???
MO to connect to MOSI
SOK stands for SCK terminal 13 Arduino
GND to connect to GND
MI to connect to MISO
POE- POE output I do not use
POE + POE output I do not use
Thank you for your help
Daniel

I think that now it works

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

here is the error message if anyone has an idea ..
The power of the radio module is at 3.34 volts with a capacitor of 10uf

Just a little radio problem to adjust and normally it's good.

Hello everyone,
I realize a project with a plug-in SHRIMP ARDUINO allowing to receive r different projects MYSENSORS.
I enclose two photos to understand my idea.
1 °) SHRIMP ARDUINO card with a 5 volts power supply
Green LED presence 5 volts,
The USB card can be deleted once the program has been loaded when it is used as a sensor or actuator.
Red LED allows you to test the card with the program 'blink Arduino',
2 °) Radio card powered by 3volts with its capacitor, and the possibility of welding a DHT22
This card would receive the main sensors and actuators MYSENSORS.
3 °) LEDs card for the bridge.

Does this project interest you?
I do not know if it interests anyone but I could provide you with EAGLE PCBs.
For now I have an error message by downloading the program, while the blinck program is working normally.
I am also attaching the screenshot of the error message.
I hope my message is understandable because it is translated by GOOGLE.
