WOW ! It works :) thanks @gohan :)
I removed the voltage shifter, added an 1µF capacitor and downloaded developpement libraries.
Also, I cleaned the configuration parameters : ./configure --my-transport=nrf24 --my-gateway=ethernet
It finally works as expected (sensor, gw on rpi3, controler on debian server) and I can ditch the uno (well, I'll find him another use).
Thanks again for the wonderfull work, it's been fun :)

I managed to connect everything but not the way I would have prefered.
Controler : Home assistant on debian server
Gateway : arduino Uno connected to debian server trough usb serial
Sensor : binary sensor (reed switch) on arduino mini.

I'm still trying to figure what's wrong with what I posted earlier.

I tried the voltage shifter since I read : (*): If you are using the nrf24 PA/LNA version you need to use a 5V->3.3V regulator because the Raspberry Pi 3.3V can't supply enough power.
Since I don't know the version...

I had no success with an arduino USB gateway but I'll try again.

I thought the controller-ip-adress=192.168.0.50 parameter was usefull otherwise the gateway would have to look guess where the controler is. I may have got everything wrong about who is initiating the dialogue. From what I read in home automation logs it's the controller who is looking for the gateway...

I'll try the 2.2.0 version.

I just checked the wiring again and tested it with a voltage shifter I used for a grove RGB LCD and I got the same results

Hi,
I'm having trouble setting up mysensor with this configuration.
Controler : Home assistant on a debian server. ip : 192.168.0.50
Gateway : rpi3, connected to the server trought ethernet. ip : 192.168.0.21
Sensor : simple door switch from the example scripts.

On both sensor and gateway the transport is a nrf24l01+ module. I bought 4 of them and they all worked in simpler projects (on both arduino and rpi).

The main problem is I can't get the rf24l01+ to work with mysensor. I checked the wiring multiple times a changed the module. Nothing changes.
I also tried to change the configuration settings but it has no effect :

I configured as :
./configure --my-transport=nrf24 --my-gateway=ethernet --my-controller-ip-address=192.168.0.50 --my-port=5003

Here is what I got every time i launch mysgw :

/MySensors $ sudo ./bin/mysgw -d
mysgw: Starting gateway...
mysgw: Protocol version - 2.1.1
mysgw: MCO:BGN:INIT GW,CP=RNNG---,VER=2.1.1
mysgw: TSM:INIT
mysgw: TSF:WUR:MS=0
mysgw: !TSM:INIT:TSP FAIL
mysgw: TSM:FAIL:CNT=1
mysgw: TSM:FAIL:PDT
mysgw: TSM:FAIL:RE-INIT

I used the wiring described in the script but without a voltage regulator. so I also checked the voltage received by the nrf24l01+ and it's a steady 3.3v.

What's wrong here ? Any help would be greatly appreciated.

On another topic, home assistant doesn't seem to provide support for mysensor 2.1 protocol. Should I downgrade to 2.0 ?
Obviously the controler can't connect to the gateway presently since the gateway isn't launching properly.
Home assistant is constantly whining about it :

Here is what I get from home automation console :

Error (Thread-13) [mysensors.gateway_tcp] Failed to connect to socket at ('192.168.0.21', 5003).

and here is my configuration.yaml extract :

mysensors:
gateways:
- device: '192.168.0.21'
optimistic: false
persistence: true
retain: true
version: 2.0,
