💬 Sensebender Gateway
-
Any idea when I'm able to order a couple of those? I'm organizing a MySensors master class for visitors of a Fast Data Event me company is holding in September. Would be great if I'd could show and promote this Gateway. I love it.
-
Im talking with the manufacturer, and hopefully we can start a prototype evaluation very soon now. My guess is that we could start shipping within a couple of months from now, if we don't find any mistakes
-
@tbowmo Great news. Also do we have any idea when MySensors 2.0 will be released?
-
We hope to release 2.0 on the MySensors meetup on Saturday.
-
@hek That would be really awe some. Then I can do a MySensors 2.0 master class. Great news. How are you doing my friend?
-
It's been a while since my latest update, but I am moving closer to production of this gateway.
I have received the first production samples from Itead
I have done hardware verification of the board. Everything seems to be ok, so we are very near the goal.
I can't say anything about pricing yet, as Itead haven't given us a price yet. But I hope that we will be able to announce that very soon (tm)
Finally a picture with all the connectors added as well
-
Great work!! Cant wait until i can buy one
Will it be possible to buy in low quantities and ready assembled?
-
We are aiming for a similar setup as for the Sensebender Micro, that is Itead is handling the production and shipping, for us. So yes, they will be SMD assembled, where you have to solder in the connectors that you need.
-
@tbowmo - thanks and again great work!
-
Can't wait to get my hands on one of these. Building a new network based on the RF69 and need a working Ethernet gateway.
-
@tbowmo please let us know when you are ready - I think this GW will be a hit. It is super small compare to mine. Though, mine is based on Mega 2560 + Ethernet shield
-
We are still waiting for price negotiations with itead.
So currently I don't have an eta of the device
-
Did you already try the W5100/RFM69 combo on the production samples?
-
A good question, I think that I have tried both at the same time.. At least I know, that the W5100 and rfm69 is working separately, and they are using separate hardware SPI ports, so they should also work combined.
-
HI @tbowmo
I am developing a similar GW board with a different SAMD chip.
Just one silly question. Could you point me in the right direction regarding which files are the ones that need to be modified so as to tell the compiler that W5100 will be connected at SERCOM1 and RFM69 at SERCOM2 for example.
Thanks, regards.
-
Spi ports are controlled in variant.cpp / variant.h files in the mysensors GW board files.
-
Sorry @tbowmo. I can't find those files in mysensors library. Are those files included or will be included with the release of your GW?
thanks
-
As said they are located in the board variant files. They are in their own repository.
Look here https://github.com/mysensors/ArduinoBoards
And here https://github.com/mysensors/ArduinoHwSAMD
The first is just an installation repository, it contains zipped files from the last one.
-
Any news on availability and pricing from itead?
-
Unfortunately not. I have asked itead studio for a price several times, but it seems that they only have one person who can do the calculations, and he is overloaded with tasks. I hope that we can have something very soon though.
-
This gateway will only run with ethernet and USB? Is there a plan to integrate an ESP for WLAN connection?
-
ESP can be programmed via arduino studio directly, and so you don't need an extra application processor to run mysensors. That is why I dropped support for ESP early on in the project (I had it in there in the first drafts of the schematics)
-
@tbowmo is there something we others can do to make itead studio handle your request faster? Mail them or something?
-
I don't think so, @hek has already pushed the person responsible for the calculations a couple of times via skype.. I do not know what is happening out there (one of the disadvantages of having manufacturers so far away, you can't just stop by to see what they are up to)
-
@tbowmo @hek Would you guys maybe willing to try any other company? There are multiple PCB manufacturers in Hong Kong. My personal experience with Itead is mixed. Their support is extremely poor - It looks like one person responsible for supporting multiple products. They are cheap, but struggling with fast expansion launching their own IOT products (Sonoff).
-
we have looked at a couple of other manufacturers in China / Hong Kong area.. But found (back then) that Itead was the best solution, as they would handle manufacturing, stock, and shipment for us, and pay us a commission of the sale which makes it extremely easy for us to handle product launches
With the other manufacturers we had to buy 100/200 units, and handle stock / shipment ourselves, and with the limited time for the project (as most of us have families and daytime jobs to take care of, besides of bringing new products into the world), this is not a feasible solution..
My contact person at Itead, promised that she would get the quotation guy to answer me today. So let's see what happens
-
I'm not sure. But I think I read somewhere that the manufacturers in china are closed due to holiday.... At least I think I read that on aliexpress.
-
I think that they just returned from holiday. I was at least in contact with itead the other dah, where I received a couple of mails from my contact person. Just need the quotation guy to wake up from his hibernation mode
-
Got this from one eBay seller when I asked why my order was delayed.
"I am so sorry for the dalay. because of National Day in China, we were from 30th sep to 5th October on vacation."
-
@tbowmo Hi! Very cool design, I especially like using of ARM microcontrollers. I have a lot of projects with SAMD20, and I want to give you a little advice for your future revision of your "Mysensors Gatevay". When I had problems with my devices work (there were crashes and hangs) I found the circuit of evaluation board called "SAM D20 Xplained Pro". After examining this circuit I saw that they apply more capacitors in the power supply than I. And I thought that use just one capacitor 100 nF not enough. So, I corrected the filtering circuit in my devices and everything worked perfectly. Below I'm showing the filtering scheme:
-
Thanks for the tip.. I took heavy inspiration from the arduino zero, which only has 100nF capacitors for decoupling.
I haven't seen any problems with stability on the prototype GW's that I have build, we also have 5 production sample GW's out in the wild, at a couple of the core group members, and I have not heard any problems from them either.
Anyways, I have noted it, and will take it into consideration if I/we decide to do a new revision of the schematic / layout.
-

@kalina
I haven't seen any problems with stability on the prototype GW's that I have build...Of course, your device may work perfectly without additional capacitors. This is just my experience.
In my devices there are large number of impulse noises, because they contain FPGA... and one more interesting thing, I have compared two datasheets on SAMD20 and noticed that in new revision they have increased the VDDCORE capacitor from 100 nF to 1 uF
-
Is there any news about selling this PCB ?
-
As mentioned in the latest announcement, pre-sales have just opened up over at itead.cc, so head over there to order it
-
Is there an option for a WiFi connection?
-
You can have mysensors running natively on the esp8266, so we decided not to support WiFi on this gateway device.
-
I find it on Itead but no announcement on mysensors.org.
-
@Fabien do you mean the gateway? It is available on https://www.mysensors.org/hardware/sensebender-gateway
Where did you expect to find it? Maybe we need to update some documentation with a link?
-
Which exact RFM69 is the footprint for? Cause it says "RFM69HCW" in some places, and "RFM69HW" in others. The footprint looks a lot like HW (https://c1.staticflickr.com/1/563/20328459340_62fa380554_b.jpg).
-
@hek : strange, this afternoon I can't see it on "news history" !
-
I did some updates this afternoon (among them the news section).
We will continue updating the Sensebender Gateway article during the coming days.
-
Oh and another question, since I've never ordered anything from ITEAD before, how do they declare the customs value? Is it safe to order more than one gateway or should I order them one by one to be on the safe side? I'm talking about "SF E-Parcel" or "Registered Air Mail" of course, not TNT or DHL.
-
@bjornhallberg, I don't remember what the value was set to on the latest package from them.
Suggest you contact them here:
https://www.itead.cc/contact-us
-
@bjornhallberg they declare a very low customs value (for my last order only 12x0.89€ ...)
I juste order the gateway today.
-
I also just order my gateway
-
This is on my most wanted purchase list now.
FYI, I noticed the spelling of "Sensebender" is "Sensbender" for this gateway on openhardware.io, so you're breaking your brand name.
Would it be possible to amend it? If you try to search for it with the original spelling you only find the two sensor Sensebenders.
-
Opps! Thanks for reporting @martinhjelmare.
-
This has been on my watch list for some time. Excellent work guys - I placed an order and looking forward upgrading my gateway.
-
Is this device capable of being a gateway for both nRF24L01+ radio and the Hope RF RFM69HCW radio simultaneously ?
I have some nRF24 nodes and see a lot of new goodies equiped with the RFM69 radio. One gateway to serve both would be excellent !
-
No, only one radio type or rs485 is possible at the moment.
-
The hardware supports both NRF and RFM69 at the same time, they share the same SPI bus, but has separate chip select lines etc.
Unfortunately the MySensors library doesn't support multiple transports, so this time it's the software that limits things.
-
Yes ! Itead send me the gateway today
-
@Fabien said in
Sensebender Gateway:Yes ! Itead send me the gateway today
I have got mine today. Very quick
-
@tbowmo
The fact, that MySensors doesn't support more then one radio, was the reason for me not to order the sensebender gateway.I am working on a gateway⁄controller based on an arduino due, which supports at least up to 3 serial gateways via hardware serial. It handles ID and time (synced with ntp) requests and does pub/sub to mqtt with readable topics.(inspired by the old mqtt client gateway)
-
@FotoFieber this is a software limitation. Hardware wise I do not see why Sensebender GW cannot handle two (nrf24l01+ and rfm69/rfm95) GWs at the same time
-
@alexsh1
The question is: will the software restriction be solved? If not, I do not care if it is a software or a hardware restriction.
-
Well, you need to hack the core anyways, if you want to accomplish your goal.
You could also help out with the core development, so we can get support for multiple transport on one gateway
-
@tbowmo
No, I don't have to hack the core. I use the serial API. From an architectural point of view, I don't see the need to change anything in MySensors. A serial controller can be built for under 20€ Including the radio. Why should I add complexity to support more than one radio support with one cpu in MySensors, if I can have the functipnality with the abstraction layer of the serial API? Please keep MySensors s simple as possible.
-
@FotoFieber simple for who? Simplicity also involve maintenance and code complexity. What about testability and regression testing? Nobody gets paid for maintaining mysensors.
-
But you ditched the sensebender Gateway, as it doesn't support multiple radios at the same time? Now you are saying that you would keep it as one radio per gateway?
This doesn't make sense
-
@tbowmo
Maybe the design of the sensebender gateway doesn't make sense to my architectural viewpoint....
-
@FotoFieber This is a question for the MySensors dev team. Sensebender can handle both radios. Currently, there is a software restriction.
-
@FotoFieber No, you do have to hack the core if you want both radios to be handled properly, i.e. to handle message queues with corresponding radios. For example, sending a message is done via rfm69 only and not via nrf24l01+
-
The architecture we use would place this kind of situation to the controller to solve. One gw per network. So one gw for nrf and one for rfm.
HW is cheap, and library should be kept simple.
-
@Anticimex
One gateway per radio, that is what I think is best.
What I try to do, is to implement a controller with arduino due for up to three serial gateways. If there would be a solution for ethernet&rfm69 I may not have invested time in this.
-
Well sensebender GW supports rfm69 with ethernet
-
@tbowmo
Yes, that is really nice.My other goal was to have a new MQTTClientGateway, as it existed with MySensors 1.1 (which is not only a gateway, but a controller too). It would have been really painful to add it to MySensors 2.1.x, as I would have to patch core files. It is much easier, to throw hardware at it.
-
@tbowmo More practical question. I have received the GW and it already has MySensors 2.1.0 software. Excellent service by Itead. Can you please help me how to map LEDs in the GW sketch? I can see that they are connected to pins 38, 41, 42, 39, 40 as LED1, LED2, LED3, LED4 and LED5. Thanks
-
you should be able to use LED_BLUE, LED_GREEN etc. defines (or even just LED_1, LED_2..) in your sketch, to access the different LED's on board the gateway. That is, if you are using the SenseBender GW hardware support files in arduino (installation instructions are here https://github.com/mysensors/ArduinoBoards)
Also, look at the board definition files, located here https://github.com/mysensors/ArduinoHwSAMD/blob/master/variants/mysensors_gw/variant.cpp
and here https://github.com/mysensors/ArduinoHwSAMD/blob/master/variants/mysensors_gw/variant.h
-
@tbowmo Excellent links, many thanks. BTW the board is working with the standard arduino samd, the problem I suppose comes with things LEDs.
-
You might be able to compile with the standard arduino zero BSP files. But the IO mapping is not the same at all.. I have swapped some pins to make routing a bit easier. Also the SPI channels are configured a bit differently than the standard arduino, if I remember right. So I will advise to use the mysensors gateway BSP files..
-
@tbowmo it is already done. Thanks to your link I have now Sensebender Gateway board added.
Waiting for an ethernet board now, it has stuck in the post
-
@tbowmo : Did you try to use this board with platformio ?
-
No, platformio is still on my bucketlist.. There is just not hours enough for everything
-
@tbowmo Ok I will install arduino IDE to upgrade it to 2.1.1
Please post here iwhen you have more information. I think I will try but I have no experience with this architecture.
-
Has anyone designed a case for the sensebender gateway ?
-
I designed one in freecad for the GW and a nrf24l01 with lna/pa and external antenna.
But I still have some fine tuning to do before releasing it, as the lid locking mechanism didn't turn out like expected.
-
Tea time..
Here is my custom box for your RFM69 Sensebender GW ! Beautiful board though
No nail no screw
Last final minor check and i release the files, sure! (i've done one for nrf too in case..)
-
@scalz beautiful box!!!
Looking forward to print it too as soon as you publish it, but mine will be with nrf24l01+. Having been running both networks, I'm so much in favour of rfm69. It just works. No more caps to stabilise power or any other rf issues.I have decided to use Moteino Mega with a built-in antenna as rfm69 gateway though - it is very small and goes inside into an RPi box. And has got more memory than atmega328p
-
@scalz Yeah ! I will print this one.
-
Little gift..
Custom box for the NRF non PA version:
A bit enlarged for NRF.
And here the 3d preview for both versions with my little cheat for bicolor as i've still not added this feature to my printer
You can see i've added a little slot near usb on the NRF version, it's for the leds indication in case box wouldn't be white (no need for white box, you can see it by transparency). I'll do the same for rfm69, and put variant stl with it or not.Next Nrf PA version, and that'll be fine
-
Thank you @scalz!
-
@scalz Please share the STL files!
-
@alexsh1 why, i don't understand
Here it is : http://www.thingiverse.com/thing:2084269
-
I'm proud to say enclosure files have been integrated in the MySensors Sensebender GW project and git.
So you can find the files here at Mysensors.Enjoy
-
Hey it should look like this?
But you see the gap between the W5100 and Sensebende Gateway.
Sorry for a very poor camera
//Mattias
-
Yes, according to the build instructions here, you can also raise the socket a bit over the pcb.
The problem is that the ethernet connector is higher than a normal IDC socket, which means you can't insert the board fully in the socket. I have searched for a higher variant of the socket, but haven't found a suitable candidate..
-
@tbowmo What I did was soldering the socket a bit higher. Not a problem with some soldering skills...
-
@scalz Thank you Sir. I am going to probably wait for the PLA version as It has been working a bit better for me.
-
Few things about the software side of this. When you plug it into your computer it appears as a "Sensebender GW", with a custom USB VID/PID. You have to override the drivers and use the "Atmel Corp. EDBG CMSIS-DAP" serial port drivers or you will have no serial port at all to communicate with the board.
Second issue, with the latest Arduino software (1.8.1), and the MySensors SAMD board package installed and MySensor library installed you get an error relating to a missing core "arduino:arduino". Solution to that one is to install the main Arduino SAMD board package which adds the necessary libraries. Secondly, after doing that you will now get another error regarding a missing "Sam.h" file, to fix that you have to manually edit the platform.txt file in "\AppData\Local\Arduino15\packages\MySensors\hardware\samd\1.0.3" with the contents of the one from "\AppData\Local\Arduino15\packages\arduino\hardware\samd\1.6.11" - just being careful to copy over the name and version lines from the top of the Mysensors platform.txt file. After that you are good to go and can finally program the board or get some data out of it
-
We are preparing a new release of the board definitions for our samd. Which fixes the issues with arduino samd 1.6.11.
It should also contain a driver .inf file for Windows 7/8, for those that needs it (it's not needed on Linux, mac or Windows 10). I had completely forgotten that windows usually needs this inf file to operate correct (I have been using Linux the last 17 years for all my private projects)
I hope the package will be out tomorrow (sunday) , as I just need to do a couple of tests to verify things.
-
Do you have any example sketch for this gateway? I want to use in my GW radio + wifi module.
-
It only support wired ethernet, and USB. For wifi we have ESP8266 gateways instead.
There are example sketches available in mysensors (see SensebenderGatewaySerial, or just plain GatewayW5100 would work if it's just ethernet module that you want to use)
-
@tbowmo Great, took a an hour or two to work out what was going on. Not used MySensors before so presumed it was something I was doing wrong. I have an RFM69HW soldered on the sensebender GW now with the serial sketch loaded and it appears to be working!
-
for info, a new Mysensors SAMD board definition file have been released (1.0.4)
Includes the following changes:
Arduino SAMD 1.6.11 supported (the latest arduino board definitions for SAMD)
Various bits and pieces regarding pin definitions are fixed (a couple of missing defines)
Windows driver .inf file added.
-
@tbowmo Compiles fine now with 1.0.4, not convinced the drivers are being automatically picked up though. I can force install them by selecting the inf but presumably you want it automatic when someone plugs in the gateway?
I notice in the arduino SAMD package they have a post-install.bat to seemingly install the inf file - possibly needed?
It could also be that i've just messed things up with my manual driver install stuff yesterday. I'm on Windows 7 by the way.
-
@tbowmo Also, I notice on Linux (Raspberry Pi 3 running Debian) the device appears as an ACM device rather than the usual TTY device that some might expect. It works fine though so no issues but may confuse alot of people - worth making a note somewhere.
-
-
@MLs reload board definition from IDE
I have a little annoying bug : I can't reset de gateway. When resetting, I loose communication with my computer (linux) same after loading a new sketch (last version with IDE 1.8.1 and def 1.0.4))
