💬 Building a Raspberry Pi Gateway

The Pi MQTT Gateway with IRQ connected may handle better the messages into a loaded network than Ethernet MQTT Gateway where IRQ is not used? (with NRF24)
Also I would like to know if I can use the other pins of RPi to connect some digital sensors directly there. -
Maybe i'm wrong but IRQ is used on all gateways if you read above :
"""
Improving throughput for nrf24
There is another method were the interrupt pin from the nrf24 modules is used to inform when a new message arrives and it's immediately added to a queue for further processing
"""
for the second part yes you can use other pins on RPi ... i have RF module NRF24L01 for gateway and DHT11 on RPi. -
Ditto, @Robinek70 !
Thank you, Marcelo Aquino, for your fantastic work .
I have Domoticz, Cacti, Heyu and MySensors Gateway running in a 30 dollars RASPBERRY PI 2, all without a glitch, all talking to each other and hopefully soon will also have Alexa for RASPBERRY PI running there also.
If in doubt, by a RASPBERRY PI and thank people who develop and support it for free instead of complaining all the time.

Can you please give me the instructions for Domoticz setup?
I have a node with DHT11 sensor and I can see mygsw service is getting messages. How do I connect Domoticz with mysensors ?
I have been following openhab until today and I'm switching to Domoticz now.

Hello, @musthafa .
For installation I used the tutorial at http://www.domoticz.com/wiki/Installing_and_running_Domoticz_on_a_Raspberry_PI. It looks like they changed the tutorial that I used to just a single curl command to install it, although there are complaints about it not working alright. You'll have to try it as I cannot reinstall mine.
Setting up MySensors Gateway is also covered in the wiki : http://www.domoticz.com/wiki/MySensors, very easy. I recommend you go thru the wiki pages as I did, they are a treasure of information, as the manual on www.domoticz.com is outdated though useful.
Good luck.

Domoticz Installation was straight forward as per their wiki.

MySensors I tried Ethernet didn't work. Virtual Serial Port worked for me. However I have 1 light (LED Test at PIN 4 of Node) & a DHT sensor. Domoticz only lists the DHT sensor. It doesn't show me the light child.

@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.

Luiz

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?

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

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/728Note that it currently requires using some pin other than CS0/CS1 for the chip-select

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.
