💬 Sensebender Gateway

[alexsh1]

@tbowmo I have just discovered that the second Ethernet module I have is not W5100 but ENC28J60. Not sure if it is supported by sensebender GW (probably using native Arduino ethernet library?).
So this module is now being returned and just to figure out any hardware issue I need to order a new W5100

[tbowmo]

You should not use soft spi, as there is separate hardware spi ports for radio and W5100.

If you load the default GatewayW5100 example sketch, then it should work out if the box. Perhaps you need to enable rfm69 instead of nrf24 at the top of the file, but that should be all that is needed.. To get a gateway up and running with W5100

[tbowmo]

@alexsh1

OK, just to recap here, you have a gateway, and a W5100. If you use that combo, and the http server example, you can ping the gateway, and Load the html files in a browser, right?

If you load stock GatewayW5100 mysensors example sketch, then does that work? (no need to redefine pins for hardware etc, that is handled by the target hardware profile, you choose in arduino)

[alexsh1]

@tbowmo I must admit I have not tried to load files in the browser when trying Ethernet sketch. Only pinging
Yes, you are correct - gateway, nrf24l01+ and w5100

[tbowmo]

@alexsh1

So gateway with nrf and W5100 is working as it should as an ethernet gateway? Then the W5100 is working with the gateway.

What is the hardware configuration that you can't get to work? Rfm69 and W5100? Together with the samd GW?

(just trying to figure out what is going on :))

[alexsh1]

@tbowmo No, sensebender GW is working with nrf24l01+ as a serial GW, but not with W5100 as ethernet GW.

Interesting observation - I cannot ping the IP any more if I load the ethernet sketch. For your understanding the sensebender GW was never working with W5100 with either nrf or rfm69. Something going wrong around W5100.

I'll hook up W5100 shield to Arduino nano to test it - I have a suspicion about it. However, even without W5100 connected, sensebender GW is showing IP as 0.0.0.0 (I set IP 10.1.1.150). Why?

[tbowmo]

If the ethernet library can't initialize the W5100, it will just write IP address as 0.0.0.0.

Can you please turn on verbose compile logging in arduino? (file -> Settings, set a checkmark at show verbose output during compilation, and choose "all" in Compiler warnings)

I just want to make sure that it is using the correct ethernet library.

[alexsh1]

@tbowmo I have verbose on already.
I think you hit the nail on the head:

[tbowmo]

It is using "our" ethernet driver, which it should be.. The default arduino ethernet driver is hardwired to SERCOM0 for SPI, while we have it on SERCOM1.

I'll try to bring up one of my own gateways with W5100 later today.

[tbowmo]

@alexsh1

Below is the startup log from my Gateway with W5100 and RFM69 attached:

As seen, the W5100 is initialized with ip address,

Telnet to the Gateway is also working:

The above is with the stock example sketch from mysensors (right now latest development branch though). The only things I changed, was to enable RFM69, instead of NRF24, and set a different IP address, to match my network settings.

Everything else is running as is, delivered from the mysensors examples..

[alexsh1]

@tbowmo if you take off the W5100 shield, does it still come up with IP please:

@tbowmo Thanks - I am assuming that I have a faulty W5100 shield in this case. Unfortunately, I have received a wrong replacement shield enc28j60 instead of W5100. Do you know if Sensebender GW would work with

#define MY_GATEWAY_ENC28J60

The one I have does not have AMS1117-3.3 on board and must be fed with 3.3V instead of 5v

[alexsh1]

@tbowmo The problem has been identified. I have used a hot fan to re-sit W5100 on the network shield.

Still cannot ping it, which means there is still a problem with the shield.
It is of a poor quality and does have multiple bridges around W5100 like this:

I found a similar problem here:
https://electronics.stackexchange.com/questions/156147/are-solder-bridges-on-chips-always-bad

At least I know where the problem is.
Thanks @tbowmo

[tbowmo]

@alexsh1

Great, that we found the problem, and thanks for reporting back here on the forum

I haven't tried with other ethernet controllers, than the W5100, And the socket for W5100 is supplied with 5V directly.

Also, I do not know if they are pin compatible?

[alexsh1]

@tbowmo I think they are pin compatible but unfortunately take different voltage. On arduino board, somebody told me that enc28j60 can tolerate 5V. It seems to be the case, as mine survived w5100 socket

EDIT: From the enc28j60 datasheet

• Operating Voltage of 3.1V to 3.6V (3.3V typical)
• 5V Tolerant Input

[alexsh1]

@tbowmo I can confirm now that everything is working fine after I tested the Sensebender GW with the third (yes, third!!!) shield. Thanks Thomas for your help!

[alexsh1]

@tbowmo The pinout is identical.

W5100

ENC28J60

I can modify ENC28J60 shield (reduce voltage to 3.3V) and test it with the sensebender GW, but it does require hardware mod

[nitroburn]

Question,
"To use the serial port in the mysx connector, you should use Serial1 in your sketches, as the default Serial is connected to the USB serial device"

What pins is the serial port in the mysx connector, I see no mention of it other than that line. I want to mirror the serial data sent to my controller via the USB port to the the serial port in the mysx connector that will then be attached to a bluetooth SPP device. Just want another way to view the radio traffic.

[tbowmo]

@nitroburn

Have you seen the documentation for MysX connector: https://www.mysensors.org/hardware/mysx?

(hint, look for Data To Module, and Data From Module :))

[Anticimex]

@tbowmo @nitroburn
Actually, it is even more clearly specified than that as DTM and DFM means Data To MCU and Data From MCU. "module" is not explicitly defining what "side" you mean. The MCU is clearly defined so DTM and DFM leavs no doubt on the direction and function of the pin.

[nitroburn]

@tbowmo @Anticimex Thanks, I was stupidly searching for the wrong combination of terms and hadn't seen DTM DFM used so I was naively looking for the word serial or UART rather than USART when I did a search. Thought I was missing something and didn't read the mysx page close enough after briefly searching it.

Thanks for clearing that up. #define MYSX_D1_DFM (00ul) & #define MYSX_D2_DTM (01ul) didn't stand out to me as serial connections.

[zboblamont]

@scalz Can somebody edit the descriptive text for this Gateway. Under 'Secure IiT Radio Network' is quoted 'Hope RF RFM69HCW' whereas under 'Setup and use' is correctly quoted RFM69(H)W.
Guess who had ordered the incorrect 'CW' module for this Gateway....

[tbowmo]

@zboblamont

Sorry about that, it sneaked through the reviews.. I have updated the page, so others don't fall into the same pitfall..

[magpern]

Is it really correct that orange, green and red led should light constantly when powered on. On some activity from the sensors the leds blink, but goes to full constant light directly.

An other thing, inclusion button. In sketch this is commented out, should it?

// Digital pin used for inclusion mode button
//#define MY_INCLUSION_MODE_BUTTON_PIN  3

For me it is like GW is in constant inclusion mode. Gateway seams to work, it shows up in controller, and as soon as a sensor is powered up, it automatically also appears in controller... feels very unsecure. Just give power to a random sensor and it is in my controller.

[hek]

@Magnus-Pernemark

You can reverse the led behaviour by defining:

#define MY_WITH_LEDS_BLINKING_INVERSE

Presentation messages is always forwarded to controller. Inclusion mode must be implemented/supported by the controller for it to work.

[magpern]

@hek Thanks, I'll try that. The controller is Domoticz. Does Domoticz have a flaw when it comes to inclusion? (I guess it must have, since any random sensor gets included automatically).

[Anticimex]

@Magnus-Pernemark I am not sure domoticz support inclusion at all.

[alexsh1]

@Magnus-Pernemark inclusion mode is not for Domoticz but for Vera. For Domoticz if you want to secure your sensors you need to use signing between the sensors and the GW and reject any sensor without signing

[magpern]

@alexsh1 Feels like this could be changed, so inclusion also would work for domoticz. A also have a z-wave module hooked up to domoticz and for the z-wave there is inclusion. Just have to find the right person for it

Yes the signing. I have tried. I want everything on the mysensors network to use signing, I have enabled the MY_SIGNING_ATSHA204, all sensors have the same keys in the chip. Is it using the signing if I have done this? I will try and hook up a sensor without the correct keys and see what happens. Just have to solder it first.

[Anticimex]

@Magnus-Pernemark there is quite extensive documentation on how to use signing. I presume you have read it? It's on the homepage (and the forum). You need to enable a signing backend and you need to enable requirement for signatures if your node is to require it (signing does not have to go both ways).
So no, if you have only personalized your atsha devices and enabled the atsha backend, it does not mean signing is enabled unless you on at least one node or gw have enabled MY_SIGNING_REQUEST_SIGNARURES.

[magpern]

@Anticimex Thanks. Yes I have read it and read it and read it... doesn't mean I understand it or know what to do, unfortunately. At this point I am only using the standard examples, the standard GWserial and standard sensebender micro sketch. Without modifications, except for the MY_SIGNING_ATSHA204.
It is so much to go through.

[Anticimex]

@Magnus-Pernemark then you support signing, but you don't use it.
There are several examples in the documentation which in code showes exactly what you need to define for various use cases.

[alexsh1]

@Magnus-Pernemark said in Sensebender Gateway:

@alexsh1 Feels like this could be changed, so inclusion also would work for domoticz. A also have a z-wave module hooked up to domoticz and for the z-wave there is inclusion. Just have to find the right person for it

z-wave in Domoticz is based on OpenZWave and z-wave protocol does require inclusion / exclusion. MySensors are natively supported by Domoticz and personally I do not see why inclusion/exclusion should be there. If you want security, please use signing.

[tbowmo]

@Magnus-Pernemark

You can disable domoticz automatic inclusion of new devices on the mysensors network, somewhere in the settings..

[magpern]

@tbowmo Ah, found a setting ""Accept new hardware/sensors" and a button for "allow for 5 minutes" that could be used as a global "include"-button

@alexsh1 well, maybe, maybe not. Don't know if I agree about not having an inclusion. Almost every device you buy you have to "pair" with something. Anyway, for now disable "allow new hardware/sensors" will do.

@Anticimex I will re-read everything and test stuff now when I have a GW and two nodes to play with.
A quick question - Is it possible to have the gateway to allow soft signing for some nodes (those without a ATSHA) and hardware signing for those with and reject everything else?

I found this sentence:

It is legal to mix MySigningAtsha204 and MySigningAtsha204Soft backends in a network. They work together.

The word backend is in plural, does it mean I need one GW with ATSHA and another with soft signing?

[Anticimex]

@Magnus-Pernemark it means literally what it says. You can mix nodes. They are fully compatible. You can have a gw with a atsha204a device using atsha backend communicating securely with a node using soft signing. Or have a node with atsha204a device and atsha backend communicate with a gw with soft signing. You could even have a node or gw with atsha204a device configured for soft signing (although that is a waste since you have hw backed support in that case which is more secure since the hmac key is readout protected). The ONLY compatibility requirement between ANY node or gw in a network is that they MUST share the same HMAC key. That's it.

[magpern]

@Anticimex Thanks again. So, really, to have hardware and software at the same time exposes the hardware key in the nodes that have soft signing, since all nodes need same HMAC, regardless of HW or SW.

I enabled MY_SIGNING_ATSHA204 and MY_SIGNING_REQUEST_SIGNATURES in the gateway
What I understand, this should activate signing (https://www.mysensors.org/about/signing and the "How to use this" part)

I then took a bender with the same ATSHA keys, but without "MY_SIGNING_ATSHA204". It showed up in MYSController and reported temp. I changed the key in ATSHA to something other then the GW, it still shows up and reports the temp. So, clearly there must be something else to change as well?

I read this in the documentation: "If this [MY_SIGNING_REQUEST_SIGNATURES] is set in a gateway, it will NOT force all nodes to sign messages to it. It will only require signatures from nodes that in turn require signatures."
I intemperate this as, the gateway will require signatures, if the node says so, but it will talk to nodes that don't require signing too.

All sketches are the default example sketches, except for the setting of the MY_SIGNING...

Maybe I am over-shooting the target? What I'm after is: my devices are mine alone and they should only report to me. My receiver (GW) should only listen to my devices and ignore the neighbor's devices. The neighbor should not be able to talk to my devices.

[Anticimex]

@Magnus-Pernemark if you are on master, yes, then a node has to require signing to make the GW require it. On development (beta) gw will require signatures from everyone if it is set to require signatures (unless a specific flag is set).
Doxygen holds the the current documentation for master and development.

[alexsh1]

@Magnus-Pernemark I would suggest you move the signing discussion into a corresponding thread. Other people may benefit reading what you have gone through

[Anticimex]

And yes, if you have nodes "exposed" you should make sure those are using atsha204a backed signing if you are afraid they might get physically abused.

[Anticimex]

@alexsh1 @Magnus-Pernemark indeed. There is a long running one here: https://forum.mysensors.org/topic/1021/security-introducing-signing-support-to-mysensors/

[magpern]

@Anticimex @alexsh1 yes should be in other thread. It started with a gateway question and migrated to a signing question. This will be the last one here, since I give up now. I will focus on building a network, and secure it later.

I'm on development branch, so I guess I just need that "specific flag". Couldn't find it in the documentation. I have it set up as the document in doxygen says, and GW should reject unsigned messages or wrong signing, documentation says, but it doesn't... Even nodes that have a different key and MY_SIGNING_ATSHA204 set, talks to the GW and reports temp.

I'll wait until beta is released

[alexsh1]

@Magnus-Pernemark
This is very simple. On the dev version:

GW (assuming you have atsha204 or use soft signing?)
MY_SIGNING_ATSHA204
MY_SIGNING_REQUEST_SIGNATURES

On a node (assuming you have hardware atsha204?):
MY_SIGNING_ATSHA204

This is it.

[Anticimex]

@Magnus-Pernemark why do you need the special flag? I just wrote that you only need that if you DON'T want your gw to require signatures from everyone. It works just like @alexsh1 wrote. And it will work like that on both bets and release after release so if you can't get it to work on beta now, it won't work on release later either.
I suggest you start posting some logs so I can see if you really have signing enabled and that all required handshaking takes place. But don't post it in this thread please.

[magpern]

@Anticimex @alexsh1 It's working now! In one of you replies (@Anticimex ), you misspelled the flag name, and I copy / pasted what you wrote. So all this time, signing was never activated. Now it is and gateway works as expected!

[Anticimex]

@Magnus-Pernemark oh, sorry about that. But I do hope the ones in the docs are correct. Good that it works now

[2rDK]

This may be a beginner-misunderstanding, but i hope you can assist me.

I had to move one of my repeaters to improve the WAF of my sensor installation.
In this process i may have messed a bit too much with the routing as i think the nodes responds directly to the gateway, but the gateway answers through the repeater. The repeater is moved, and the signal does no longer reach the node, resulting in a head ache (FPAR fails).
I read the debug-section and I think i need to clear my eeprom to allow for a new routing to happen.

This proved more difficult than I had anticipated. below is my software stack/process:

• Downloaded Arduino 1.8.3 for non admin install
• Downloaded Mysensors Library v2.1.1 using Library manager
• Downloaded Arduino SAMD Boards (32-bits ARM cortex-M0+) version 1.6.11 using Boards manager
• Downloaded Mysensors SAMD Boards version 1.0.4 using Boards manager

I then rebooted my machine for good measure and uploaded the ClearEepromConfig-example to the gateway. No output in the serial monitor.

I then searched a bit on the forum and added:

#if defined(ARDUINO_ARCH_SAMD)
    while (!Serial) {} 
 #endif

In the setup()-part. This enabled me to get some output from the gateway. Unfortunatly it only returns Started clearing. Please wait...

I then did some more digging, and apperantly i2c_eeprom_read_byte() fails. So i searched some more on the forum and found I2C eeprom write fix for SAMD. So i tried the above once again but this time with Mysensors Library v2.2.0-beta (dev branch) just to see if anything changed. It didnt.
What did i miss ?

[Fabien]

Hi,
After weeks of tests, it doesn't work well with ethernet and RFM69HW. Every 2 days, I need to power off and on the gateway. Controller can't connect (OH2).
for some reasons, serial doesn't work on my odroid C1 with openhabian.

[korttoma]

Ever since lightning took out my original RFM69 W5100 GW I have been having trouble with the replacement GW I built so now I want to use my Sensebender GW for this instead. On the GW I have allso 4 buttons and 4 relays so my question to @Anticimex is:

Witch pins on the MYSX connector do you recommend for the buttons and relays?

I was thinkin:
Buttons:
MYSX_D1_DFM
MYSX_D2_DTM
MYSX_D3_INT
MYSX_D4_INT
Relays:
MYSX_D5_PWM
MYSX_D6_PWM
MYSX_D9_A3
MYSX_D10_A4

Can I assign the pins like this in my sketch:

const int relayPin[] = {MYSX_D5_PWM, MYSX_D6_PWM, MYSX_D9_A3, MYSX_D10_A4};       //  switch around pins to your desire
const int buttonPin[] = {MYSX_D1_DFM, MYSX_D2_DTM, MYSX_D3_INT, MYSX_D4_INT};   //  switch around pins to your desire

Here is the complete sketch, please comment if something can be improved:

 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the ethernet link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
 *
 * LED purposes:
 * - To use the feature, uncomment MY_DEFAULT_xxx_LED_PIN in the sketch below
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error
 *
 * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

@korttoma you can use any pin that can provide the type of functionality you need (for example, don't expect that using an analog pin for digital data to work). Just keep in mind that by using certain pins, you might have to give up features you might like to use later on (like in this case you take the dfm and dtm pins, so you have "taken" the UART pins if you ever plan to use that for your board).
As for the definitions, I am not sure. @tbowmo made the mappings for that port. I believe it looks good.

[tbowmo]

@korttoma
Like @anticimex said, you will loose possibility of using the serial port if you use the dtm/dfm lines.

But besides that, you are free to use all the ports as digital input/output, except the i2c pins as we have an i2c eeprom that is connected to the same pins.

[korttoma]

Thanks @Anticimex and @tbowmo I have the GW up and running with one external sensor now. I just need to connect the buttons and relays to test those.

I'm not sure if I will ever need the UART pins but I will make the hardware so that I can easily change the pins used for buttons and relays.

btw, what is the use cases for UART pins?

[Anticimex]

@korttoma if you have peripherals on your daughter board that communicate using a serial protocol it makes sense to leverage any hw UART capable blocks on the main board. The MYSX standard just indicate that if the main board has such capability, the interface is available on those two pins. You can of course bit bang it on any digital io (depending on core clock) if you need several interfaces.

[Anticimex]

@korttoma that said, note that the dtm and dfm pins also serves as general digital io, so you can use them like any Dx pin.

[korttoma]

Button and relay pins I assigned seem to work correctly but now I managed to release some magic smoke from the Sensebender GW board shorted something by mistake and at least FB1 is tost. Can I just shor FB1 to see if the board is stil alive or do I have to replace FB1? Seems like nothing else was damaged (at least I hope so) since it was GND and Vraw that was shorted.

Edit: Just confirmed that it is only FB1 that was destroyed the rest seems to work just cant power it from the USB anymore. Hope I can stil write to it.

FB1 is just a filter to suppress spurious RF (if any) on the gnd wire exiting the board. So it can be shorted. The gateway should function fine without it.

[Mr6510]

Hi All,
I have purchased a SenseBender Gateway, tested the MySensors MQTT code etc on it and thats all good.
Now I want to experiment with my own code on it. I notice that in the example code there are some references to the onboard LEDs, such as;

static uint8_t leds[] = {LED_BLUE, LED_RED, LED_GREEN, LED_YELLOW, LED_ORANGE};

which is great, I will use those to manage the LEDs in my sketch.
What I'd like to know is where are LED_BLUE, LED_RED etc actually defined? What file? The reason I ask is that I also want to know which pin is connected to the RFM69 RESET pin. On the schematic for the SenseBender it is labelled RESET_RFM on the SAMD21 chip, and is physical chip pin 23 and also PB10. I don't know how to use that in my sketch, so if I had a macro like there is for the LEDs then I could just call that.
I'm assuming that if I find where LED_BLUE is defined I may find info about the other pins I also want to use

Thanks,
Paul

Thanks again,

Received a new ferrite bead and soldered it to my device. The bead showed 0 ohm with a multimeter so I don't know if it is the real deal but it seems to work even if it is not pretty:

[tbowmo]

at DC it should be close to 0 ohm, but on higher frequencies it should act as a resistor.

btw. it seems like the old one had exploded?

[korttoma]

@tbowmo said in Sensebender Gateway:

That's what happens when you short Vraw to GND on the MYSX connector in one of those facepalm moments (we need an :facepalm emoji!).

[Fabien]

I have a lot of problem with this gateway. First I think it was caused by network module but with serial sketch I have a lot of issues. After 2 or 3 days, gateway crash. If I remove some sensors reporting every 30 seconds it crash but later.
This morning, all leds are off on the board. After powering off and on it was ok.
I'im using RFM69 with Openhab2 as controller.
Is someone experience same issue ? I will fall back to my old Jeelink gateway (ATmega328 based).

[tbowmo]

I have used my sensebender gateway for more than a year now, only difference is that I use NRF24 radio.. Haven't had any hickups yet..

Which version of mysensors are you using?

[Fabien]

I'm using version 2.1

[tbowmo]

@Fabien

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?

@stefaanv said in Sensebender Gateway:

[stefaanv]

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

@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..

[8667]

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.

[Mitja Blazinsek]

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.'

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

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?

[rolandow]

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
