Razberry - Hello world

[esteban-uo]

Hi all,
First of all, I would like to thank a lot this awesome project!

I'm trying to test this project together with a Razberry (I think 2016) (which I can use fine through the zwave.me smart home / API )

I'm facing the issue just at the beginning interview:

Any hints on what could be wrong, will be really appreciate it. Thanks!!

I'd assume that either the path is wrong or the serialport blocked by another application that uses it. You can't have multiple drivers access the controller stick/module at the same time.

thanks a lot for your reply @AlCalzone !

Indeed the serial port was being used by the zwave default server. Just for others facing a similar issue, you can stop it with /etc/init.d/z-way-server stop

However, after the interview is completed it raises an exception: Failed to initialize the driver: undefined is not a function. I'm attaching the logs. logs.txt

Thanks!

Since this has turned into a bug report, let's continue here please:
#2077

[esteban-uo]

it turned out I wasn't using properly the handlers after the nodes were ready. thanks a lot @AlCalzone for your very fast support!
