💬 Building a Raspberry Pi Gateway

[ysinh]

A tiny hint for the users of domoticz :
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB20
make
sudo ./examples_linux/mysGateway -d

:) i hope this helps
then in the hardware setup
MySensors Gateway USB
serial port: /dev/ttyUSB20

I'm a bit confused about gateway and controller. Can I use a Pi as both gateway and controller?

Yes!

I'm using the virtual serial port option and one of the things that I notice is that the port gets created where the tty group only has write access.

pi@raspberrypi:/dev/pts $ ls -l
total 0
crw--w---- 1 root tty  136, 0 Oct 10 18:49 0

I can change it manually but if I reboot the raspberry pi it goes back to write access only. How do I get it to be created with 'rw' access?

[jerseyguy1996]

Nevermind....When I set "--my-serial-groupname=tty" in ./configure it works.

Where do I put the security stuff for the signing?

[GertSanders]

@NiklasO

Signing is not yet supported in the current Raspi Gateway.

Ok, thanks.
I now see that in this thread. Did not see the earlier discussion in the comments on the main page. Hope to see support soon.

I have disabled signing for the time being but I want it on ofc. ;)

what's about RS485 transport on raspberry pi? especially from wired RS485 mysensors network to MQTT

[raulandresmoch]

Can you use the RP as gateway and also as controller?

[NiklasO]

@raulandresmoch
Sure. I use this with Domoticz on my Pi.
"MySensors Gateway with LAN interface" as hardware pointing to 127.0.0.1:5003
Also, I can connect with other controller software like MYSController from my other computers to my Pi-IP at port 5003.

[marceloaqno]

@b0rmann I could add support for RS485, but I'll need your help to test because I don't have the hardware.

[DrJeff]

The line above
./examples_linux/mysGatewaymsyGateway -h
needs to be corrected to
./examples_linux/mysGateway -h
Thanks for all the hard work! Awesome!

[mfalkvidd]

@DrJeff Thanks for noticing. It should be fixed now.

i am ready. after compiled and upload example node sketch i have on rs485 to usb convertor (/dev/ttyUSB0) output nice mysensors data:

I noticed the "improve rf24" section was added. and it mentioned high cpu.
i set mine up a few weeks ago and am not using an interrupt on my radio.
my cpu is only 2-3%
I'm curious if the high cpu problem is seen by many?

also a 2nd question.
if i were to add an interrupt. how can i "re-configure" my setup to include that new -switch
or do i have to remove everything and re-clone from git hub and start over?

[shfg]

Thanks for this excellent port. I'm having an issue running it as an MQTT gateway on the RPi (Model A). It compiles without hassles, but cant make a successful MQTT connection. I get the following:

mysGateway: Starting gateway...
mysGateway: Protocol version - 2.0.1-beta
mysGateway: MCO:BGN:INIT GW,CP=RNNG---,VER=2.0.1-beta
mysGateway: TSF:LRT:OK
mysGateway: TSM:INIT
mysGateway: TSM:INIT:TSP OK
mysGateway: TSM:INIT:GW MODE
mysGateway: TSM:READY
mysGateway: MCO:REG:NOT NEEDED
mysGateway: MCO:BGN:STP
mysGateway: MCO:BGN:INIT OK,ID=0,PAR=0,DIS=0,REG=1
mysGateway: Attempting MQTT connection...
mysGateway: connected to 127.0.0.1
mysGateway: Attempting MQTT connection...
mysGateway: connected to 127.0.0.1
mysGateway: Attempting MQTT connection...
mysGateway: connected to 127.0.0.1

... those attempts recurring every 15 seconds or so, and in that time, no other activity is processed.
From the code, I would have expected 'MQTT connected' rather than 'connected to 127.0.0.1'?

I have mosquitto running on the pi in this case - which is working perfectly in other tests. Both serial and ethernet gateway modes compile and run perfectly, only the mqtt mode not working.
Has anyone else had a similar issue?

[ericvdb]

@marceloaqno what about gpio interrupts, is that supported?

I'm thinking to use a RPi as a pulse counter for water, electricity and gas with no radio, just ethernet or mqtt.
In combination with a I2C display, this could be a nice project ;)

Greetz,

Hi,

I have a raspberry Pi 2 that I've installed MyController on. This works fine, I can access it via the browser. I have also wired up an NRF24L01+ module to the GPIO pins on the Raspberry Pi. And I have followed the steps under "install and build", which seem to have worked fine. I didn't make any changes to the conf file. However now Im stuck. How do I setup the Raspberry Pi with the NRF24L01+ as a gateway in the MyController Gateway setup page in Safari?

[marceloaqno]

@shfg There were some reports about this problem in the past, do you see any error messages in your mosquitto log?

@ericvdb yes, you can attach a function to handle an interruption like this:

uint8_t mode = FALLING;	// Valid options are: CHANGE, FALLING, RISING
uint8_t physPin = 16;	// Choose a pin that fits your needs

void irqHandler(void)
{
	// Process the interrupt
}

void setup() {
	attachInterrupt(physPin, irqHandler, mode);
}

Support for I2C was added in the latest version.
