Cannot run MySensors on RPI 3

[GRDL]

I struggled with RPi gateway for ages without success. The easiest solution by far is to run the gateway on arduino and interface it to RPI through a serial gateway. Its not a very elegant solution but works. I did some investigation and came to the conclusion that the problem with RPi gateway is to do with the low level library that communicates with the radio but never found a fix.

Hi, thanks for your answer.

If you are telling me that you have had the same issues as me, I am willing to do your method. True, not an elegant solution but I just want it to get up and running...

When you say "run the gateway on arduino and interface it to RPI through a serial gateway", do you mean you built a serial gateway as mentioned here: https://www.mysensors.org/build/serial_gateway and then with an USB cable you connect it directly to your RPI? Am I understanding this correct?

If yes, could you please tell me which parameters you have used while building your MySensors on your RPI. Would this be correct:

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

Did you leave the value for --my-serial-pty was shown above? Did you add any other parameters?

Sorry for asking so many questions but I cannot fully grasp the concept of MySensors without MQTT.

I appreciate your response and thank you in advance :)

I've been running the Ethernet gateway (port 5003) on my raspi without issues for several months now.

@kkanedaa It looks like the development version finally works with your nrf module. Regarding the MQTT connection refused: Are you sure your MQTT broker does not need a username and password?

@grdl on rpi3 is running fine, I have 2 radio modules too

This weekend a had also issues with nrf24 on rpi3. I'm using openhabian image and it was all working ok. But my sd card got corrupted and i had to reinstall openhabian. So I downloaded the newest image burned and ran my setup script - which should give me running and restored setup of OpenHAB, MySensors and couple more. But mysensors didn't work ... I found that the mysgw was failing to initialise nrf module (!TSM:INIT:TSP FAIL) - wierd because even with the binary that was working in previous setup i got the same error ... same hardware only new software ... So I connected my oscilloscope to spi pins and to my amazement there was no life on MOSI pin ... I even try with python to send something trough SPI - the same result. Then I compiled the mysgw with BCM driver ... and it worked ! Even better, I recompiled again with SPIDEV driver AND STILL WORKED !!!

So @kkanedaa try to compile with BCM driver - maybe it will work, for me it did.

@rozpruwacz did you use mysensors 2.1 or 2.2?

[rozpruwacz]

@gohan I was trying both master and developement branches (I believe ...).

[rozpruwacz]

@gohan I am sure that the old binary mysgw that was working before openhabian update and was not working after openhabian update was 2.1.

[gohan]

A lot of users reported 2.1 no longer working with the more recent raspian images, while development version is known to be working better.

Hello all,

Thank you for all the replies. It is very much appreciated :)

I am starting to think that I am misunderstanding the concept of MySensors. I thought that the RPI would handle both RF24 communication and MQTT. That is not correct...right?

And your Ethernet gateway, did you use an Arduino to make the gateway and connected it to your RPI, or is the RPi itself the gateway?

Can't I just install Mosquitto on my RPI and use it as a gateway? I'm really confused here.

All I did was add MySensors (dev) to a fresh install of Raspbian Stretch Lite.

Could you please tell me what exactly you did, I would appreciate it a lot.

@rozpruwacz Unfortunately I am still fairly new to this, and I do not know what you mean by BCM and SPIDEV... but my ultimate goal is what you are doing: using MySensors in combination with openHABian (but currently I am trying with MyController since it seems easier).

Anyways, I hope some of you guys can help me out setting up MySensors on RPI3 :)

Thanks again for all the replies.

to compile the gateway with BCM driver You need to add to ./configure invocation special option, I don't remember now how it is named ... run ./configure --help and find this option - look for spidev and bcm keywords.
and after that run make install :)

Hi all! Good news! I managed to make it work, finally :)

Here is what I did (for those who might face the same problem):

1. Fresh install of Raspbian Stretch Lite
2. Install Mosquitto MQTT
3. Install MySensors

./configure --my-transport=nrf24 --my-gateway=mqtt --my-controller-ip-address=[RPI-IP] --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1

(Replace [RPI-IP] with your IP)

4. "make" then "sudo ./bin/mysgw -d"

I got the following output

pi@rpi-mycontroller:~/MySensors $ sudo ./bin/mysgw -d
mysgw: Config file /etc/mysensors.dat does not exist, creating new config file.
mysgw: Starting gateway...

mysgw: GWT:RMQ:MQTT CONNECTED
mysgw: GWT:TPS:TOPIC=mysensors-out/0/255/0/0/18,MSG SENT
mysgw: Received SIGINT

5. Auto start service with "sudo systemctl enable mysgw.service"

Thank you for all your inputs, guys. Really really appreciated. I am looking forward playing with MySensors. Very excited :D

Install MySensors

developement branch as 2.2.0-rc.2 suggests that.
So you only added --my-transport=nrf24 to what You started with ? (which seems to be the default so it shouldn't matter ...)

Yea, I'm confused too. But basically a fresh install of Raspbian did the trick..

If you had failed mqtt connection it was most likely caused by mqtt broker non accepting anonymous connections
