@subutux it is mentioned as stated above that you need it, it is just skipping all the info that are in datasheets and are not stricly necessary to make the gateway

Well, I for one would like to know why we need to step-down from 5v to 3.3v. Just a simple statement that the LNA version requires more power that only the 5v can deliver on the pi.
@mfalkvidd Yeah I would mention it there. It mentions to use a regulator but not why.. I've read that line & was like, why? That's when I've started a search in the forums here.

@subutux I've updated the text. Do you think it is ok?

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,

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

--my-controller-ip-address=192.168.0.50

I think you can ignore that parameter. Did you try making a USB gateway or ethernet gateway with an arduino? Why the voltage shifter? Did you add a capacitor on the 3.3v supply of the nrf24? You could also try with the 2.2.0 version from development branch that has some fixes

qkzk

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.

qkzk

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.

qkzk

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 :)

gohan

Voltage regulator is strongly suggested when you are going to have the gw sending out messages and also a bigger capacitor will help

I'm trying to understand the need for a separate Gateway if the Ras Pi is the host of the controller. Is it possible to use OpenHab on the Pi AND have the RF transceiver connected to that same Pi and skip the ethernet adapter w/ Arduinos? Or, if you have to use ethernet, could you use localhost as the IP? Or is there a technical reason why that wouldn't work (or would work, but in a totally different way)? Thank you.

gohan

Did you read the article?

rozpruwacz

@Andy-Pethan there is no need, where You read that ? I have a raspi with openhab and mqtt gw on single board. works very well.

Andy Pethan

@gohan @rozpruwacz After reading a couple times it still wasn't clear that everything could run on one device (single Ras Pi), though that seemed like the intuitive answer. Thank you for confirming as I buy up parts.

Andy Pethan

I figured out my problem -- I had the image and concept of this tutorial (http://www.instructables.com/id/Uber-Home-Automation-w-Arduino-Pi/) one tab over and never noticed at 3am that I mentally blended the articles. Sorry, everyone.

gohan

In fact I was wondering what in the article wasn't clear.

Going crazy here.
I did get success with MySensors and first Arduino node on a fresh Raspbian (last image) and branch development. All ok!

Now I want re-do on other SD (same Pi, same WIring, same Radio). I did put "old" sd on a secure location and re-start from scratch.

I did compile with:

./configure --my-transport=nrf24 --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB020

and answer is:

[SECTION] Detecting target machine.
  [OK] machine detected: SoC=BCM2835, Type=rpi1, CPU=armv6l.
[SECTION] Detecting SPI driver.
  [OK] SPI driver detected:BCM.
[SECTION] Detecting init system.
  [OK] init system detected: systemd.
[SECTION] Saving configuration.
[SECTION] Cleaning previous builds.
[OK] Finished.

Make ends with no error.

The debug

sudo ./bin/mysgw –d

locks here:

mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0-beta

And no other lines.

I Repeat, same PI, same Radio, same wiring. If I try other SD, all goes ok and I can use it on domoticz.

Thank you

OK, re-re-done on fresh install and all went ok.

I think that problem was when I deleted the PI default user and created another one.

I did follow the gordon guide: https://gordonlesti.com/change-default-users-on-raspberry-pi/

Probably a permission issues changing or not changing root?

Thank you

Hi all

Hope someone can help MySensors noob :) I try to do Raspberry pi 3 gateway with nrf24 module.

Hardware:
Raspberry pi 3
nrf24 module
3.3v 0.5A regulator.
status leds (3pcs)
Domoticz Beta

I start with this instructions:
https://www.mysensors.org/build/raspberry#improving-throughput-for-nrf24

commands what i use:
git clone https://github.com/mysensors/MySensors.git --branch master
cd MySensors
./configure --my-transport=nrf24
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway (try ttyUSBMySensorsGateway too, but now help)
./configure --my-transport=nrf24 --my-rf24-irq-pin=15
./configure --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18

make
sudo ./bin/mysgw -d

After that i get error what is same to that instruction site:
http://i.imgur.com/jpiaMdC.png

I douple check wiring that seems to be all right. I think Linux console tell wrong wiring, if wiring is problem? But anyway i douple checked that wiring.

Hope someone can help me with this problem.

I try many times different settings, dont know do i need delete some old files or can i try again and again do configure and give "make" command.

@lassivv please don't post the same question in multiple places. Posting in multiple places will result in people trying to help you in one place, even after the problem has been solved in the other place. That is a waste of people's time.

Anyone trying to help @lassivv please post in https://forum.mysensors.org/topic/7050/multi-node-project-mysensors-noob-raspberry-gateway-problem
