💬 Building a Raspberry Pi Gateway

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

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 ?

[gohan]

No, it uses very few cpu

@Richard van der Plas: I strongly recommend to use MQTT instead of Ethernet gateway, as it is a standard way for 2 processes to communicate, and platform-agnostic.
HASS comes with an embed MQTT broker taht works out of the box.
Plus:

• you can easily mock either your sensors network or your controller
• it does support secure communication
• you can add other clients to observe the event, e.g. to log what is coming from/what is sent to the gateway

I suggested ethernet because it's easier to setup and configure, mqtt is the next step.

Hi
I also have problem to get the NRF24L01+ chip to work with the RPi3.

I find that the masterbranch don't recognize the board as RPi3 and sets SoC and Type as unknown.
But if i take development branch it´s detecting RPi3 and seems to work correct.

This is result from development Branch configure:
[SECTION] Detecting target machine.
[OK] machine detected: SoC=BCM2837, Type=rpi3, CPU=armv7l.
[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.

This is result from Master Branch configure:
[SECTION] Detecting target machine.
[OK] machine detected: SoC=unknown, Type=unknown, CPU=armv7l.
[SECTION] Checking GPIO Sysfs.
[OK] /sys/class/gpio/export found
[SECTION] Detecting SPI driver.
[OK] SPI driver detected:SPIDEV.
[SECTION] Detecting init system.
[OK] init system detected: systemd.
[SECTION] Saving configuration.
[SECTION] Cleaning previous builds.
[OK] Finished.

This is the result from cat /proc/cpuinfo:

Hardware : BCM2835
Revision : a02082

That's odd, I have the 2.1.1 compiled on mine rpi 3

[marceloaqno]

@pettib @gohan There have been some changes in /proc/cpuinfo in newer versions of kernels which leads to a wrong detection.
The problem was fix in #827 and will be available in the master branch in the next mysensor release.

[gohan]

I'm using dietpi and I compiled it like 2 weeks ago..

@Richard-van-der-Plas what is this: HASS ?

[Richard van der Plas]

Ok, i am standig on a crossroad it seems, i have to build a new gateway but i am also interested in the MQTT option, this is between mysensors & HomeASSistant i presume? i have some ESP's lying around unused, but i have 0 knowledge of mqtt (i dont think my hass has it running by default)

[gohan]

Just go with ethernet first that is easier, get used to it then take your time to learn MQTT. Of course MQTT is more advanced has authentication and encryption but it adds complexity to initial setup.

[Richard van der Plas]

Damn, just connected as in manual, but gives an error : mysgw: !TSM:INIT:TSP FAIL
Double checked the GPIO pins (except 15 cannot find that one) but seems ok

[Richard van der Plas]

NM, used GPIO numbers instead of Pin numbers RTFM :)

I always have a mysgw: accept: Bad file descriptor error when I launch a new ./bin/mysgw -d Exact problem is the following:

mysgw: bind: Address already in use
mysgw: Failed to bind!

And I always need to kill the process first. Is this normal ? (I'm in LAN GW)

Thanks!
