I just did. When I also have a Domoticz controller connected to the gateway:

However, I found out that the DI00 (=IRQ) on the RFM69 never gives a rising edge...
I'm suspecting that the RFM69 is not being initialised properly... I added some debugging in the RFM69 code to see what registers are being written and read:

Can't get the RFM69HW to work on RPI. I tried the following:

1. I installed on an old RPI1 (clean Rasbian install). Same results as on my Domoticz RPI-3.
2. Setup the original RPI3 as a node, using the 2.2.0-beta code. I verified that in this case the RFM69HW actually transmits (I can hear it burst on 868.000 MHz). However, it is unable to connect to an existing Arduino 2.1.1 gateway.
3. I built an Arduino 2.2.0-beta serial gateway. Even then, the RPI as a node fails to connect to the 2.2.0-beta serial gateway.
4. I built an Arduino 2.2.0-beta node. This node is able to connect to the above gateway.

There seems to be something different in the radio network between the RFM69HW on the RPI and the RFM69HW on the Arduino. But I'm unable to find out what the difference is :-(.

The RPI RFM69HW will not communicate with the Arduino RFM69HW. When the RPI is a gateway, the RFM69HW will not physically interrupt when another node is trying to connect. When the RPI is a node, the RFM69HW on the ARduino does not interrupt either.

Did anyone get the RFM69HW working on the RPI? I'd really like to get this beautiful piece of code working!

[gohan]

I have to ask a stupid question : did you use a logic converter between rpi and rfm69 radio?

[ftw64]

@gohan There are no stupid questions, right :-)? But perhaps a stupid answer: no, I did not use any logic convertors. The RFM69 is 3.3V and as far as I know, so are the GPIO pins on the RPI. But I might be mistaken, of course... Should I use logic convertors?

At the moment I have no idea where it fails. Perhaps I need to give it a rest for a couple of days to think it over...

I followed the steps as given on the web site (git branch development). Connected the RFM radio (7 wires: Vcc, GND, MOSI, MISO, SCK, NSS, DI00). Only modified MyConfig.h with regard to the NETWORKID (100 --> 101; my 'production' MySensors runs at 100) and enabling "MY_DEBUG_VERBOSE_RFM69". I configured with:

% ./configure --my-debug=enable --my-config-file=/usr/local/etc/mysensors.dat --my-gateway=ethernet --my-transport=rfm69 --my-rfm69-frequency=868 --my-is-rfm69hw
% make -j 4
% sudo bin/mysgw -d

The gpio pins on raspberry pi are 3.3V. https://raspberrypi.stackexchange.com/questions/3209/what-are-the-min-max-voltage-current-values-the-gpio-pins-can-handle

[mfalkvidd]

@ftw64 that configure command looks like an ethernet gateway. Could you post the configure command for your "RPI as a node" as well?

[marceloaqno]

I forgot to mention in the guide:
To communicate with the RPi using the RFM69 radio, all of your nodes need to use the new RFM69 driver available in the development branch.
To make the change, add the following line to the node sketch:

#define MY_RFM69_NEW_DRIVER

[gohan]

@marceloaqno you forgot just a little little insignificant detail 😂

[marceloaqno]

@gohan @ftw64 sorry for all the trouble

[gohan]

It's OK, don't worry. We need to update the guide with the new instructions 😀

[marceloaqno]

@gohan Done!

[ftw64]

@marceloaqno Thanks! That indeed does the trick! And no worries, it is my own decision to play with beta(!) code (and it was a fun weekend troubleshooting it - I learned a lot about the structure of the MySensors code)!

Only 'bad' thing is that 2.2.0 is not compatible with my existing nodes :-).

I appreciate all the work that has been put into MySensors.

[Fat Fly]

This is really stupid. :D RFM69 radio need powered separately ?

[gohan]

They shouldn't, but it's always a matter trying 😀

[Richard van der Plas]

How will this work with HASS running on the same pi ?

[gohan]

It's the same as it was running on separate hw, you will only set ip address of the gateway in hass

[Richard van der Plas]

so i can attach the NRF24L01+ to the pi running HA, make it a Ethernet Gateway and point to his own ip adress ?, will this be a long job with converting from a USB connected GW (Arduino with local sensors ? )

[gohan]

That's pretty much it. I don't know what is your current setup and what sensors you have, but is should not be a long job. Anyway you can install the ethernet gateway and when you are done you take care of the sensors

[Richard van der Plas]

excellent, will the cpu utilisation be much higher that with a usb connected gw ?
