💬 Building a Raspberry Pi Gateway

Can I install mysensors on a openhab installed RPi ?

@Robinek70

$ sudo mysgw -h
Usage: mysgw [options]

Options:
  -h, --help                 Display a short summary of all program options.
  -d, --debug                Enable debug.
  -b, --background           Run as a background process.
  --gen-soft-hmac-key        Generate and print a soft hmac key.
  --gen-soft-serial-key      Generate and print a soft serial key.
  --gen-aes-key              Generate and print an aes encryption key.
  --print-soft-hmac-key      Print the soft hmac key from the config file.
  --print-soft-serial-key    Print the soft serial key from the config file.
  --print-aes-key            Print the aes encryption key from the config file.
  --set-soft-hmac-key        Write a soft hmac key to the config file.
  --set-soft-serial-key      Write a soft serial key to the config file.
  --set-aes-key              Write an aes encryption key to the config file.

To generate a soft hmac key, run:

sudo mysgw --gen-soft-hmac-key

and set it using:

sudo mysgw  --set-soft-hmac-key=KEY

For example:

$ sudo mysgw --gen-soft-hmac-key
SOFT_HMAC_KEY | 7F3F1A1C1EA32B72BF4BEDE2D16543971C26442F69572177D9CCDE393BFB8126

The next line is intended to be used in SecurityPersonalizer.ino:
#define MY_SOFT_HMAC_KEY 0X7F,0X3F,0X1A,0X1C,0X1E,0XA3,0X2B,0X72,0XBF,0X4B,0XED,0XE2,0XD1,0X65,0X43,0X97,0X1C,0X26,0X44,0X2F,0X69,0X57,0X21,0X77,0XD9,0XCC,0XDE,0X39,0X3B,0XFB,0X81,0X26

To use this key, run mysgw with:
 --set-soft-hmac-key=7F3F1A1C1EA32B72BF4BEDE2D16543971C26442F69572177D9CCDE393BFB8126

$ sudo mysgw --set-soft-hmac-key=7F3F1A1C1EA32B72BF4BEDE2D16543971C26442F69572177D9CCDE393BFB8126

The same process applies to generate/set the other key types.

@aand @Tag @jirm MySensors uses its own nrf24 drivers, and OrangePi is not currently supported. It will be in the future.

[jirm]

@marceloaqno

You mean the error posted @aand is because that?

You mean mysgw use own NRF24 drivers that is not supported on OPI although he have running Raspbian version?.

In any case, if so will be really fine if mysgw software allowed (or provide information about how to do it) to use any NRF24 driver (ex. TMRh20 fork that is working fine on OPI) and maybe too Hope RFMXX (I´m most interested in this last transceivers) because I think that generally speaking make a rigidly link with a type of hardware is not the best thing that can be done to really give the best functionality to any application.

Still keep waiting for anyone here than can help to install mysgw softw on OPI.

Thanks for your information

Best regards

@marceloaqno, Thanks a lot

[luizrrocha]

Ditto, @Robinek70 !

Thank you, Marcelo Aquino, for your fantastic work .

I have Domoticz, Cacti, Heyu and MySensors Gateway running in a 30 dollars RASPBERRY PI 2, all without a glitch, all talking to each other and hopefully soon will also have Alexa for RASPBERRY PI running there also.

If in doubt, by a RASPBERRY PI and thank people who develop and support it for free instead of complaining all the time.

'nuff said.

@jirm If you try to use the nrf24h radio you will get the same error as the @Tag post:

In file included from examples_linux/mysgw.cpp:74:0:
./MySensors.h:258:2: error: #error No support for nRF24 radio on this platform
#error No support for nRF24 radio on this platform

For @aand error, it's what you mention in your early post, a gcc compiler issue.

MySensors nrf24 drivers uses the SPI interface to drive the module, it's the same driver for all supported platforms (RPi, esp8266, atmega328p, ...), this way it is easier to maintain.

I understand that it must have been frustrating to find out that it does not work for the OPi but there isn't much I can do to help you. I bought one too, still waiting to arrive.

[marceloaqno]

@musthafa I'll give it a try. What version of openhab are you using?

[Tag]

@marceloaqno

Thank you for your help here!! would be great to have mysgw on the OPI!
I am using armbian on a OPI zero, so let me know if you need any further info.

(Also using an RPI, which runs mysgw with direct connected radio like a charm!)
Kind regards,

Tag

@marceloaqno said "MySensors uses its own nrf24 drivers, and OrangePi is not currently supported. It will be in the future."

I wish it worked now, but I don't mind waiting. Just to clarify where I'm coming from -- Orange Pi One hardware running Armbian. Thanks!

I'll be keeping watching the updates!

OpenHab 2

[jirm]

@marceloaqno

Really thanks a lot for your work and very much appreciate you try to help us on our "fight" with the OPI board.
Sadly in this moment I cannot work because I'm out of time to try install all softw stuff on my OPI and try help much more to push it working with mysgw and so on.
I don't understand so much why is not working out of the box and the driver issue found and/what hardware communication issue are only on OPI with that similar derived Raspbian OS like Raspberry, and too not understand why cannot work on OPI because that SPI bus issue you say.
@aand reported nrf24 module work very well with TMRh20 driver, so seems hardware are OK on OPI for the module and I suppose still only discover and hopefully make it work avoiding the driver issue you say to compile properly mysgw softw.
Anyway, I only hope that anyone can help mainly here to make work mysgw on OPI too, and adapt it to work on Armbian, because OPI is a really good choice for HA controller board and sure in near future much people use it.

Is there any chance to substitute own nfr24 driver mysgw with the TMR20h, at least for testing purposes on OPI?

If any mysgw "code" people are reading this maybe can try to help us with some idea to try workaround the compilation issue on OPI.

Best regards and again many thanks!

PD: Only for test SPI purposses on armbian this can help (post 248) :

@musthafa Openhab2 works using mysgw configured as an ethernet gateway. This is the guide I used: https://github.com/tobof/openhab2-addons/wiki

[hausinger]

Hello.

I'm also using a orangepi one and wanted to build the gateway on it. But i didn't want to use the nrf24 but a usb to rs485 converter. But if i want to compile it, i get also the same error with the nrf24 and that it is not supporting platform. Why?

Also if i want to build a serial gateway with a connected arduino on usb port, i got the same error with the nrf24

[musthafa]

@marceloaqno thank you.

I have already installed OpenHAB 2 on my RPi. Can I install mysgw on to the same RPi ?

[aand]

@hausinger -- are you running armbian on your orange pi one?

[Oli]

How can I update MySensors Gateway from 2.1.0 beta to 2.1.0 stable/final release?

[marceloaqno]

@musthafa Yes, set the IP Address to 127.0.0.1 in your openhab for the ethernet gateway.

Yes, I'm running on armbian on my orange pi one

@aand

Hi again!

I spend some time seeing and reading some of the files from the mysensors github build and I see some things that can help to understand why the error raised to @aand trying to compile on OPI.

First say that I´m not a coding expert, so please be nice with my if I´m wrong and say something stupid ;-)

I see in the .configure file that the machine detection have H3 Soc and this are fine detected , but then I see that selecting type and CPU flags seems not properly selected to match OPI specs , because on OPI soc H3 have a cpu armv7 (not armv8) and is a A20 and not A53.
So maybe that cpu "selection" is not correct for H3 soc , and is so easy try if anyone that have OPI and have time can change only that values in the config file and try to compile.
All the values on the A20 line seems correct for the OPI H3 soc, so only needed copy them from the A20 line to the H3 line, and give a try.

File Configure
