💬 Building an Ethernet Gateway

[gohan]

@itbeyond said in 💬 Building an Ethernet Gateway:

"You can build an Ethernet gateway using almost any Arduino model."

I believe that "almost" is the right word, since in fact the basic Ethernet gateway can run on many devices but as the requirements increase you need to step up the HW, I don't see it as a big problem: just as you need more IO pins then a standard UNO you go to a Mega2560.

I give up - at least if someone is thinking of building this gateway and wanting to use security they can hopefully read this thread before they start and will look at a higher level controller before they purchase the hardware. I am only trying to help others with what to me is still a simple and easy fix alas I must have upset the apple cart.

There is no big problem at all, just that it is really simple to know right now, with technology available today, if you need an Ethernet gateway and signing then use a Mega 2560 or better for the Ethernet Gateway controller to ensure you have the ram. @mfalkvidd - You state variations increase exponentially and most not under library control however using the MySensors Library and building the hardware shown and documented on this page using the sketch provided (completely under control of MySensors) you will need a Mega 2560 or better if you intend to enable signing (also under control of the Library). Do not get me wrong I really love the whole MySensors thing and have over 30 devices up and running and have enjoyed the whole learning thing however simple requirements (IMHO) like this should be detailed.

Hopefully this post will help the next person, it certainly would have help me and I am sure I am not the only one.

@itbeyond signing is a completely optional feature of the library. One part of a great many optional features. It is a delicate tradeoff of providing detailed instruction and keeping documentation at a level where users actually care about reading it.

Hallo,
I`m running this ethernet-gateway with w5100 shield on uno.
In the log of iobroker I always see this message again and again:
mysensors.0 2018-01-26 11:10:58.942 error Error for "192.168.178.133": Error: read ECONNRESET

I cannot find a solution in the forum of iobroker and also nothing about it in this forum.
By the way: In the list of objects in iobroker there is always a child id 255 without any state or value.
Is it an issue ?
Perhaps of iobroker?
Any solution?

Look at the gateway log and see if you get any error

[jopebe]

Here the log from debug:

From here only reading nodes.

[gohan]

Can you try with latest mysensors 2.2?

[jopebe]

I did.
Error comes once, than for minutes no error. And now the error disappeared out of the log.
I don`t understand .
Thank you for the hint.

[gohan]

So did you solved the problem?

[flyyboyy]

Hello, all. Nuuubeee here, though been doing MUCH reading/studying. I had previously (before stumbling upon this site) decided to go with MRF69HWs. I see that the code can be un-commented for this radio, but having difficulty with pinouts and mismatching pin anmes: the RFMs (appear) to have no corresponding pins to the NRFs CE and CSN pins. The MRF uses NSS and D100 pins, not labeled as such on the NRF. Same use with different labels? I've poked around looking for hints and tips about wiring the MRFs to work with the W5100, though so far, haven't found what (I think ) I need.

Thanx!

[mfalkvidd]

@flyyboyy hi and welcome to the forum!

Is this what you need?

[flyyboyy]

Have seen and studied that, though at the top of this page it mentions some necessary changes for use with the W5100:
"The W5100 ethernet module has problems sharing SPI with radio. To solve this, we put the radio on a couple of other pins and use so called soft-spi. That's why you have to wire the radio a little differently here than on the usual sensors. "
I assume that for this reason the link you replied with would not work. Some times I get into trouble assuming things; if those connections work for the gateway, I guess I'm good to go (and just didn't realize it).
Thanx

[flyyboyy]

I did look a little closer to the page you referenced and noticed your pin "color coding" was identical between the two radios, even though those two pin names were different. Would it be safe to interpolate those same "color codes" between the radio and the Arduino (using Pro Mini) even though the pin names are different?

[mfalkvidd]

Thanks for clarifying @flyyboyy
The following are used for SPI:
NSS (also called S̅S̅, SSEL, CS, C̅S̅, CE, nSS, /SS, SS# according to wikipedia)
SCK
MOSI
MISO

and yes, I think they use the same colors on the nrf and rfm instructions. But I am not sure about CE vs CSN on the nrf24.

I have updated the table for w5100 to include the NSS naming.

I created a case for this gateway.

OK, who's up for a WHOLE LOTTA handholding? Dang, guess I'm getting denser the older I get.
Is this page the place to solicit help, or should I start a new topic in the forum? I searched there for answers to my yet-unstated questions but found nothing. Guess I am the only one that doesn't get it. . .
TIA for any takers

[flyyboyy]

By the way, the questions at this point relate directly to the Ethernet Gateway -- that's why I was asking if this page was the proper place to ask

[mfalkvidd]

@flyyboyy here or in a new thread doesn't matter that much - as long as you don't post the same thing in multiple places.

https://forum.mysensors.org/category/5/troubleshooting is a good category for troubleshooting

The post at the top of that page lists the most common problems, how to troubleshoot them, and what information is usually required to help so you can get help as quick as possible.

[flyyboyy]

I kinda expected that it should go into the forum; I posted it in the General Discussion category, then even missed indicating I was looking for help -- it's simply titled "Ethernet Gateway." Oh, well. . .

Thanks

WizNET W5500 Ethernet module

For your information.
A W5500 module can also be used. The wiring is the same as for the W5100 module (with A0, A1, A2). The Arduino code must be changed in two places:

1. use as Ethernet module type
   #define MY_GATEWAY_ENC28J60

2. #include <Ethernet2.h> instead of #include <Ethernet.h>
