Gateway Addon for Hass.io

[hautomate]

@ghiglie hmm, not sure. Would you please update your repo with the latest and I'll try a reinstall and have a closer look?

sorry, I'm out for work :( I'll do ASAP tomorrow!

EDIT: Updated!

Will be watching with interest. I'd like to move to hass.io but this is the one thing stopping me.

Haha! I forgot to tell you that I have no idea what I'm doing :)

The 'run chmod' command is still missing in the dockerfile.

Wondering what the status of this is. Would love to try it out as I have migrated to hassio and would love to integrate mysensors gateway back on the same rpi.

I'm also trying to make a hassio addon for the mysensors gateway which is connected on the same raspberry pi 2.

If I run the docker image with --privileged then it runs correctly: it manages to read from the nrf2401, it connects to the MQTT server and publishes incoming messages.

However, if I run the container without --privileged (like hassio does), the mysgw program does not output anything else after:

: Starting gateway...
: Protocol version - 2.2.0
: MCO:BGN:INIT GW,CP=RNNGL---,VER=2.2.0
: TSF:LRT:OK
: TSM:INIT
: TSF:WUR:MS=0

I'm running the container like this:

docker run -it --rm --cap-add SYS_RAWIO --device /dev/mem --device /dev/gpiomem local/mysgw

If I run a strace on the mysgw binary, I see:

bash-4.4# strace mysgw -d 2>&1 | grep open
open("/sys/class/gpio", O_RDONLY|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 3
open("/sys/class/gpio/gpiochip0/base", O_RDONLY|O_LARGEFILE) = 4
open("/sys/class/gpio/gpiochip0/ngpio", O_RDONLY|O_LARGEFILE) = 4
open("/sys/class/gpio/gpiochip100/base", O_RDONLY|O_LARGEFILE) = 4
open("/sys/class/gpio/gpiochip100/ngpio", O_RDONLY|O_LARGEFILE) = 4
open("/etc/mysensors.dat", O_RDONLY|O_LARGEFILE) = 3
open("/dev/urandom", O_RDONLY|O_LARGEFILE) = 3
open("/dev/console", O_WRONLY|O_NOCTTY|O_LARGEFILE|O_CLOEXEC) = 5
open("/dev/console", O_WRONLY|O_NOCTTY|O_LARGEFILE|O_CLOEXEC) = 5
open("/dev/console", O_WRONLY|O_NOCTTY|O_LARGEFILE|O_CLOEXEC) = 5
open("/etc/mysensors.dat", O_RDONLY|O_LARGEFILE) = 5
open("/dev/console", O_WRONLY|O_NOCTTY|O_LARGEFILE|O_CLOEXEC) = 5
open("/dev/console", O_WRONLY|O_NOCTTY|O_LARGEFILE|O_CLOEXEC) = 5
open("/dev/console", O_WRONLY|O_NOCTTY|O_LARGEFILE|O_CLOEXEC) = 5
open("/proc/cpuinfo", O_RDONLY|O_LARGEFILE) = 5
open("/proc/device-tree/soc/ranges", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/dev/mem", O_RDWR|O_SYNC|O_LARGEFILE) = 5

It looks like it can't open a device which is also described in https://www.mysensors.org/apidocs/group__BCM2835grp.html

It seems to be a symlink to some device in /sys, but this directory is empty somehow.

bash-4.4# ls -al /proc/device-tree 
lrwxrwxrwx    1 root     root            29 May  7 15:10 /proc/device-tree -> /sys/firmware/devicetree/base
bash-4.4# ls -al /sys/firmware
total 0
drwxrwxrwt    2 root     root            40 May  7 15:34 .
dr-xr-xr-x   12 root     root             0 May  7 15:34 ..

That's how far I got. Does anyone know how to make this device available within the container without having to use --privileged?

Hi @kwek, sorry for taking so much to reply. We've been taking the same path!

Same here. I've been trying some time ago, if I get to start the container in privileged mode it runs without any problems!

So, I've been looking to how enable the GPIO on the board to the container, using the ResinOS guide: https://docs.resin.io/learn/develop/hardware/gpio/

...but I got nothing of use. You see anyway that the GPIO definitions are under the /sys/class/gpio/ device tree...

I hope to have some more spare time to test this.

@ghiglie Here's an add-on that uses a pi gpio pin. Maybe it will help.

https://github.com/pantomax/hassio-addons/tree/master/rpi-rf-receiver

It's discussed in this thread:

@hautomate Thanks! I didn't notice it at all.
EDIT: A quick look:
@pantomax in config.json "only" has:

    "devices": ["/dev/mem:/dev/mem:rw"],
    "privileged": ["SYS_RAWIO"],
    "gpio": "true",

...while I put an overpowered:

  "devices": [ "/dev/mem:/dev/mem:rw" ],
  "privileged": [ "SYS_RAWIO", "SYS_ADMIN", "NET_ADMIN" ],
  "gpio": "true",

so... it should work :(

Did you get this up and running?
