💬 Building a Raspberry Pi Gateway

[Oli]

OK, I did it, I f....g did it, and guess what...
s...t happened again.
Everything went as it should, no errors at all, but no ttyUSBMySensorsGateway...

log error message:
2017-01-03 19:56:38.784 MySensors: Using serial port: /dev/ttyUSBMySensorsGateway
2017-01-03 19:56:38.785 Error: MySensors: Error opening serial port!
2017-01-03 19:56:39.785 MySensors: retrying in 30 seconds...

and again...
and again...
...

any help would be appreciated.

Hello,

Could someone answer: if i have RPi NRF24 GW, how I could connect MYSController from other computer (for example from Windows computer)?

1. Is it possible to make that type connection with RPi NRF24 GW?
2. May I use some integrated web server for this type of connection in RPi to make it work? Is there are easier solutions?

EDIT: no matter, already answered it by myself :)
Its easy becose it's like Ethernet GW.

@Oli: when you do a "ls /dev" is ttyUSBMySensorsGateway shown ?

[luizrrocha]

@Oli: by the way, the name of the port you used is ttyMySensorsGateway, not ttyUSBMySensorsGateway:

@mfalkvidd I could not find ttyMySensorsGateway on Domoticz. Only ttyUSB0, ttyUSB20 and ttyAMA0. Even after I did ./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway

Is the gateway running, ie, "ps -ef "grep my" shows a process there ?

Cheers,

Luiz

[luizrrocha]

@Oli: sorry, correct syntax is ps -ef | grep my

@Oli : the port name is actually ttyMySensorsGateway, you have to correct the definition of the gateway on Domoticz to use it....

Luiz

[luizrrocha]

@jacikaas : on MYSController go to Settings -> Gateway -> TCP/IP and add the IP address of the Gateway and use port 5003. It works even if the gateway is feeding data to Domoticz, so you can monitor your sensors in "raw" mode.

Cheers,

Luiz

[Oli]

@luizrrocha as You can see, on the picture above, I've wrote that ttyUSBMySensors.... is from my previous backup copy. On the same pictures You can also see that I can choose only from three serial ports: USB0, USB20 and AMA0. Thera are no ttyMySensorsGateway despite that it is present after ls /dev.
And that's the problem, I dont know how to make it present in the serial ports popup menu.

[luizrrocha]

@Oli : why not remove the old definition to avoid any trash information and restarting Domoticz to make shure it rereads the port info before creating the new entry ?

And I do not understand why if you are running domoticz and the gateway on the same Pi, why not use a ethernet gateway and set 127.0.0.1 and port 5003 on the Domoticz gateway entry. I did that and never had to worry about USB ports at all.

Of course I did that, I started from the scratch... but when it did not work I try to restore my backup... but it did not work also...

simple... I have no free LAN on my rotuer... there is more, I also have raZberry daughter board (Z-Wave) connected to same Raspberry Pi GPIO port. And till today everything works perfect until... "Better is the enemy of the good" ;-)

[Oli]

OK I found the solution (thanks to @luizrrocha). I change

./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway
to
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSBMySensorsGateway and now its working.

Question is, It's only workaround (in my case) or there is bug in the installation guide?

[luizrrocha]

@Oli : if both the gateway and Domoticz run on the same Raspi, there is no physical network involved, hence the 127.0.0.1 dummy local address is used by Domoticz to talk to the gateway on the same machine, just using port 5003... and since you use localhost (127.0.0.1, a virtual network) there is no need to create a virtual USB port which is what you did...

[Oli]

@luizrrocha interesting... step by step instruction?

[luizrrocha]

@Oli: delete the Makefile.inc file on mysensors folder
./configure --my-gateway=ethernet
make
sudo ./bin/mysgw -b
go to domoticz and create a new MySensors Gateway with LAN, inform 127.0.0.1 as the address and 5003 as the port...

that should do the trick.

[carlyler]

@Oli luizrocha's configuration seems interesting, but just in case your still wanting the serial, from above, has worked for me in the past, but I have since switched to OH2:

@ysinh said:

A tiny hint for the users of domoticz :
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB20
make
sudo ./examples_linux/mysGateway -d

:) i hope this helps
then in the hardware setup
MySensors Gateway USB
serial port: /dev/ttyUSB20

[Wackid]

I am also not get it to work in Domoticz tried the USB serial and ethernet way.

It's a testing pi. Where i didn't connected the radio. Because it's still in the Nano. Could that be the issue? I guess not.

Hi!,

I started a new topic for Mysensors Gateway on OrangePI (OPI), Here

Hope this is okay,

Kind regards,

The Pi MQTT Gateway with IRQ connected may handle better the messages into a loaded network than Ethernet MQTT Gateway where IRQ is not used? (with NRF24)
Also I would like to know if I can use the other pins of RPi to connect some digital sensors directly there.

[Wackid]

@Oli
Stupid question... Did you mount the radio? Because I thought I would like to test if it works. (without radio) but that doesn't work.

Mounted a radio and ethernet gateway is working.
