💬 Building a Raspberry Pi Gateway

ericvdb

Would it be possible to connect a I2C display to display some information, and drive that display from within mysGatway.cpp ?

marceloaqno

@ericvdb I2C is the next thing I'll do as soon as I finished adding support for signing.

jerseyguy1996

@marceloaqno Amazing....adding the short delay fixed it! I'm curious why that is the case. Do you have an explanation for that?

marceloaqno

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

Patrik Söderström

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!

jerseyguy1996

@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?

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

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.
