💬 Sensebender Gateway

tbowmo

Could you try the latest dev, and see how that behaves?

Fabien

@tbowmo : with wich RFM69 driver ?

tbowmo

@Fabien legacy, unless you would reflash all your nodes with the new driver as well. (they are not compatible)

Fabien

@tbowmo : Just flash my SBGW today with arduino 1.8.5, last boards.txt and dev branch of mysensors.
We will see if it's more stable. All my Node still in 2.1.1

stefaanv

Which driver to use on Ubuntu 16.04 ?

stefaanv

Hi, I'm trying to activate a sensebender gateway in OH2 on Ubuntu 16.04, however I'm having trouble setting up the serial port. Is there a how-to somewhere ? I suspect the serial port name is /dev/ttyACM0, but I'm not sure. How can I test ?
MySensors bundle is reported to be active, but there's no messages coming in. I set the log level for mysensors to DEBUG, but nothing on the log.

stefaanv

Here is my configuration file (mysensors.things)
Bridge mysensors:bridge-ser:gateway [ serialPort="/dev/ttyACM0", sendDelay=200 ]
{
humidity keuken_vochtigheid [ nodeId="3", childId="2", smartSleep=true ]
temperature keuken_temperatuur [ nodeId="3", childId="1", smartSleep=true ]
}

I suppose ttyACM0 because of
stefaan@home:~$ dmesg |grep -i tty
[ 0.000000] console [tty0] enabled
[ 22.328631] 8086228A:00: ttyS4 at MMIO 0x81420000 (irq = 39, base_baud = 2764800) is a 16550A
[ 22.329059] 8086228A:01: ttyS5 at MMIO 0x8141e000 (irq = 40, base_baud = 2764800) is a 16550A
[ 23.106128] usb 1-4: FTDI USB Serial Device converter now attached to ttyUSB0
[362074.592743] cdc_acm 1-3:1.0: ttyACM0: USB ACM device

There seems to be a premissions problem om the port :
stefaan@home:~$ cat /dev/ttyACM0
cat: /dev/ttyACM0: Permission denied

doing 'sudo usermod -a -G dialout openhab' doesn't help

Anyone any ideas ?

stefaanv

ttyUSB0 is a (different) RFXcom device

zboblamont

@stefaanv I can only suggest scanning the ports. When I connected the Gateway to the Pi3 it came up with /dev/ttyS0 instead of the listed options, although I ultimately ended up changing to a Pro-Mini as the radio did not work, and connected direct to the GPIO the serial port it worked with.

tbowmo

it should pop up as ttyACM0 or ttyACM1 (if you have another usb device that enumerates first and gets ttyACM0)

I added the following to /etc/udev/rules.d/10-local.rules file:

ACTION=="add", ATTRS{idVendor}=="1209", ATTRS{idProduct}=="6949", SYMLINK+="ttyNRF24"

What that does is to create a symlink from the real device to ttyNRF24, so regardless of what I add to my rPI, i always know that ttyNRF24 is for my gateway.

(and then I use /dev/ttyNRF24 for the serial port in my controller)

stefaanv

@tbowmo Definately ttyACM0
However, the setserial command returns information that doesn't look good : port0 and IRQ0. Does the board need a driver under Linux ?

stefaan@home:~$ sudo setserial /dev/ttyACM0
/dev/ttyACM0, UART: unknown, Port: 0x0000, IRQ: 0, Flags: low_latency```

tbowmo

@stefaanv

No, it doesn't need a driver..

I get the same for mine, if I use setserial:

thomas at jarvis in ~ 
>sudo setserial /dev/ttyNRF24 
/dev/ttyNRF24, UART: unknown, Port: 0x0000, IRQ: 0, Flags: low_latency
thomas at jarvis in ~ 
>ll /dev/ttyNRF24 
lrwxrwxrwx 1 root root 7 nov 11 13:39 /dev/ttyNRF24 -> ttyACM1

Btw. the permission problem.. You are logged in using your normal user (stefaan) and then you set permissions for openhab user? (see below). Have you tried setting the permissions for your user, and then cat /dev/ttyACM0?

@tbowmo OK, is working now after restarting the bundle in OH.
Must have been the permission problem after all.
Thanks for your help !!

When I try to compile SensebenderGW sketch with signing features, I receive a bunch of errors. What am I missing?

and the same type of errors reoccurs multiple times.

Anticimex

@rzylius I think you have an #include in the sketch for the atsha driver. Try to remove that #include from the sketch.

rzylius

@Anticimex yes, when I delete #include atsha driver line, it compiles well. thanks.

Fabien

@tbowmo After 2 month on the dev version, no more problem with the gateway. Perhaps it's time to made a new stable release ?

tbowmo

@Fabien

It's on the todo list..

I am looking for Gateway that will get me the results to MQTT but will support encryption + signing. That mean it should be easy to add new signatures (recompile/reflash) the module

I suppose if I use Sensebender with LAN module it will be a pain to do that

Is this doable if I use Orange zero as USB host for the Sensbender and let it act as serial gateway, then convert serial to mqtt with software on the Linux side? Also is it possible to reflash it easily this way? I do not want to rewire the hardware each time a add new node.

tbowmo

@8667

Is it over the air encryption / signing that you are aiming after? Then that is possible with the gateway, it has the ATSHA204 onboard for signing capabilities. And it also works with the W5100 module attached. The Gateway have 256Kb of flash onboard, so it has "enough" room for both network stack, and signing.

rzylius

Are there performance limitations to be considered for mysensors and SensebenderGW specifically. Will the gateway handle the load of signed communications if rules will be firing messages to different sensors like 1-2-5-10 per second?

Anticimex

@rzylius if you use the atsha204a chip, it is the single wire interface that limits your throughput. I have no figures, so best is to just test how fast you can push messages through. Of course there is overhead in the OTA handshaking as well. That would probably be the bottleneck if you use software based signing.

rzylius

I see in logs, that the whole process of signing and communicating to the node takes a bit more than one second. I do not know how to make a stress test properly, so I hoped that somebody else did it my question is if gateway will handle load by putting messages in some pipeline, or I should try to make sure that messages are fired with some spaces.

Anticimex

@rzylius The signing process is blocking, so it should not accept messages if a signed message exchange is in progress. But I have not tested that extensively with "aggressive" controllers.

im trying to program in arduino ide, installed board... bu when compiling it write mi an error 'The current selected board needs the core 'arduino:arduino' that is not installed.'

mfalkvidd

@mitja-blazinsek You'll need to install the Arduino SAMD board as well. I have just now updated the readme.

dklinkman

Just got my Sensebender GW and soldered it up. Adapted the serial sketch to Ethernet and it almost worked. Found some posts on this topic that helped me locate and fix my config error. Now all is well. Thanks! --edit-- added photo

And I got a Sensebender Micro soldered up and running also!! Just temp and humid so far. Too cool

Is it possible to use the sensebender board as MQTT gateway? Not Ethernet?

Soloam

Yes it is! I use I'm using it as a MQTT gateway for some time

Christian Schulte genannt Trux

First: Great work! My GW is working very well!
I wanted to know for what I can use the SD-Card.
My idea is to fetch the logs in the serial and write them to the SD-Card.
But I don't know where. Is there a point in the mySensors core where I can fetch all logs?

Forgive me if this isn't the right place to ask; but as a beginner, where do I start? How can I order this thing, or any other stuff from OpenHardware.io ? I see so many design files, I'm not sure what to do with them. Soldering the thing I can probably manage, but is there a guide available how to order the PCB, and maybe the parts as well?

Sesnebender GW can be ordered from Itead:

https://www.itead.cc/mysensors-gateway.html

Other openhardware.io projects maybe ordered either (1) directly from a link; pcb only (2) you can download eagle files and upload them to pcb manufactures like oshpark.com (3) you can purchase the final product. So a generic answer to your question is it depends

I do not think there is a guide here, but if you go to oshpark.com there is a guide how to order a pcb. Parts (BOM) can be ordered from Aliexpress, eBay or more reputable supplies like digi-key or mouser

Hi!
I'm trying to use sensebender GW as ethernet gateway. I loaded the stock W5100 sketch compiled with samd 1.6.21 defs but it didn't worked. I have been trying out different things and realized that it works with 1.6.12 defs. Now it's working but I'm stuck with an old version. Anyone with the same problem? Maybe I'm missing something?
Also I found out ethernet library in 1.0.5 defs is outdated. I have been trying to use stock one (v2.0) without success. Anyone has tried?
Thanks.

hi
when i try compile sketch only with change radio to rfm69hw i have this:
Arduino:1.8.9 (Windows 10), Płytka:"Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"
