💬 Building a Raspberry Pi Gateway

@musthafa : look on the MySensors forum for the MYSController, install it and you can monitor the messages going to the gateway.

Most likely your declaration of the LED output pin on the MySensors arduino is not correct. I still did not use arduinos as actuators with MySensors so I will probably not be of much help here.

In OpenHAB it worked as a dimmer. Later on OpenHAB was stuck and my mobile app was frozen. Then I start discovering Domoticz. If it can be discovered in OH2 why not in Domoticz ?

Thank you for the answer, I am happy to get a confirmation about sensors works on a Pi Gateway. Since at least one of my sensor is analogue, I still have to add an Arduino board to the gateway, I plan to connect it via USB.
I have tested and get very good results with Home Assistant controller running on a Pi where I add sensors directly on Pi and to an Arduino (USB to Pi).
The Ethernet Gateway do not use IRQ: https://www.mysensors.org/build/ethernet_gateway
Nor the nodes: https://www.mysensors.org/build/connect_radio Even if the wire is connected at Arduino pin 2, is mentioned: Note: The IRQ is currently not used by the MySensors library so it can be left un-connected
If you know how to connect and manage this IRQ on Arduino sketch, please let me know.
I have built this some time ago and works without the IRQ connected. Now I have updated the MySensors to 2.1.0 , IRQ is still unconnected and works the same. As far as I see, it is used for the Pi Gateway. I plan to migrate to this configuration of Pi Gateway, but I would like to get more info before change my working system:

• this IRQ improve the reliability? (sometimes I have encountered problems due the load of NRF24 network with many messages)
• I would like to set retain=true for the MQTT Gateway, this will improve the reliability.
  I already addressed the last question somwhere else, still waiting for more info if somebody know.
  Thank you

After installing a Raspberry Gateway, is this output OK, or have I forgotten something?

mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0-beta
mysgw: MCO:BGN:INIT GW,CP=RNNG---,VER=2.2.0-beta
mysgw: TSF:LRT:OK
mysgw: TSM:INIT
mysgw: TSF:WUR:MS=0
mysgw: TSM:INIT:TSP OK
mysgw: TSM:INIT:GW MODE
mysgw: TSM:READY:ID=0,PAR=0,DIS=0
mysgw: MCO:REG:NOT NEEDED
mysgw: MCO:BGN:STP
mysgw: MCO:BGN:INIT OK,TSP=1

I configured with (should be a serial gateway with a controller on the same machine):

./configure --soc=BCM2835 --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorGateway --my-serial-groupname=dialout --my-debug=enable

Has there been any progress on the RFM69 version? Looking at the repository, it looks like some of the code is there. I did find this RFM69 driver for the Pi that has a LowPowerLabs interface. Would this help in moving forward?

https://github.com/dconstructing/rfm69

thanks for all the work on this - a great community moving things forward.

@Mihai
you can attach analogue sensor to ESP2866 with espeasy firmware ... more info here : http://www.letscontrolit.com/wiki/index.php/ESPEasy ... i'm using one ESP8266-12E and i have good results and Uptime: 74209 minutes (usb powered).
i'm using IRQ on NRF24L01 connected to my Rpi, but i don't have many sensor with nrf+arduino (only 2) and i had no problems ... i don't if IRQ improve the reliability and i never play with irq fron nrf on arduino.
regarding retain=true have a look here : http://www.hivemq.com/blog/mqtt-essentials-part-8-retained-messages
for more reliability on mqtt i think you can use qos=1 ( The broker/client will deliver the message at least once, with confirmation required.), but all depends on your set-up .. not all messages need special attention.

@Mihai I have not done any extensive testing with IRQ functionality in RPi, I plan to do it in the future, so for now you will have to test it for yourself.

@Madhias Yes, this is the expected output, the gateway is now waiting for messages to arrive.

@pjeran Yes, there is a work in progress with many improvements: https://github.com/mysensors/MySensors/pull/722

Is it possible to use the second ISP on my raspberypi 3 to connect NRF24L01+ and what will be the wiring diagram, also what have to change in mygsw library

[PhracturedBlue]

I have created a patch to enable the use of the RFM69 with a RaspberryPi gateway without the use of an Arduino gateway board.

It has only been tested with my configuration, but it seems to work well for me.

Pull request is here with configuration instructions:
https://github.com/mysensors/MySensors/pull/728

Note that it currently requires using some pin other than CS0/CS1 for the chip-select

@PhracturedBlue

Thanks for the link and the work, I will give this a shot.

As far as I understand, MySensors relay on PubSubClient for MQTT and it does not allow to publish messages with QOS=1 or 2, only 0.
Retain is different that QOS, it offers the possibility to recover the state for a device that loose connection for a while (e.g. after a restart). I find it very usefull. For example I have to restart the controller. When come back I got all states to their real values if retain=true. Otherwise they goes to the default, usually 0.
I have now 6 nodes, each with several sensors and relays.

please help :(
every time after reboot i have to run this code

sudo ./bin/mysgw -d

so built a virtual usb but after reboot ....

how put this code in startup ? :( please help thank you

[marceloaqno]

@Reza

From the Building a Raspberry Pi Gateway article:

If you wish to install:

sudo make install

The last command will provide instructions for your system on how to start the gateway on every boot.

[Reza]

@marceloaqno
i do it but after reboot serial lost again :(
just with command work again

sudo ./bin/mysgw -d

[Reza]

@marceloaqno
i'm sorry
after sudo make install i must run this lines:

 sudo systemctl enable mysgw.service
 sudo systemctl start mysgw.service

sorry thank you

[Reza]

@marceloaqno can you build a rs485 gateway on raspberry pi ?

[eyesoft]

@Mihai yes you are right

[Shantanu Mhapankar]

This data that I get when I run ./mysgw --d , where is it stored and how can I get it to push it on cloud? Please help.

@Shantanu-Mhapankar

Data is not stored... to store the data and do something usefull with it (or not) you need a controller. I use mycontroller, and from this software you can "push" data to an external server.
I use my controller, but i am sure that other controller software also has this feature.

[Shantanu Mhapankar]

@Tag , The controller must be using something to get the data right? How can we do it directly without using the controller?
