💬 Building a Raspberry Pi Gateway

@jerseyguy1996 It's probaly related to this: https://www.mysensors.org/build/raspberry#improving-throughput-for-nrf24

Just installed MySensors on one of my Raspberry. Works really great! :) Picks up the other node I have over NRF without trouble. Next I will try and add some sensors directly on the Raspberry.
Big thanks for this!

@marceloaqno Oh that makes sense :-) I'm wondering if that is also what is causing my problem with reconnecting when the node loses contact with the gateway. The node connects perfectly when the gateway is running but if it loses the connection for any reason it can't seem to be able to reconnect and just goes into a loop of attempts. Here is the debug info from the node:

So far so good!

Next I shutdown the gateway to simulate a lost connection:

Its still doing what I expect it to do. It begins attempting to reconnect:

It looks like the first few messages to initialize the reconnect go through okay and then it misses everything afterwards. If I reset the node it will connect again with no problems.
What do you think might be happening here?

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

gvorster

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

Yes!

jerseyguy1996

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.

NiklasO

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. ;)

b0rmann

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?

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?
