@luizrrocha interesting... step by step instruction?

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 said:

@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 ?

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...

@luizrrocha said:

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.

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"

@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.

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.

@mfalkvidd hah... thats a good question, don't know. After dozen or more reinstallations, spending hours on Google I finally make it work. Got some notes but frankly I am worrying it will happen again. Hahaha

@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

I wanna update not to re install of MySensors. I thought about something like ./updaterelease or ./updatebeta... I spend hours of make it work before, so I leave it as it is. No time or nerves for fighting next couple of days.

@eyesoft same errors
