Problem when calling lgtv.sh from child process in node.js

[blefjell]

Hi and thanks for your great libary! I have succesfully installed it on my pi and I can controll the TV from a command line. I am trying to integrate it into my HAP-Node.js, so I can for example turn on my TV. To do this I call lgtv.sh as a child process with exec('/home/pi/LGWebOSRemote/lgtv.sh on'); Unfortunately I get this error: stdout: stderr: Traceback (most recent call last): File "lgtv.py", line 87, in ws = LGTVClient() File "/home/pi/LGWebOSRemote/LGTV/init.py", line 217, in init super(LGTVClient, self).init('ws://' + self.__hostname + ':3000/', exclude_headers=["Origin"]) TypeError: cannot concatenate 'str' and 'NoneType' objects

exec error: Error: Command failed: /home/pi/LGWebOSRemote/lgtv.sh inputChannelDown Traceback (most recent call last): File "lgtv.py", line 87, in ws = LGTVClient() File "/home/pi/LGWebOSRemote/LGTV/init.py", line 217, in init super(LGTVClient, self).init('ws://' + self.__hostname + ':3000/', exclude_headers=["Origin"]) TypeError: cannot concatenate 'str' and 'NoneType' objects

Can you give any advice on this? Thanks in advance!

Yeah, it seems that it can't find the config file and load it correctly.

In your HAP-Node.js you are not the same user as in command line.

LGTVClient load the config file from home path of the user: class LGTVClient(WebSocketClient): def __init__(self, hostname=None): self.__command_count = 0 self.__waiting_callback = None if os.path.exists(os.path.expanduser("~/.lgtv.json")): f = open(os.path.expanduser("~/.lgtv.json")) settings = json.loads(f.read()) f.close()

Thanks for the quick replies!! I am sorry, I don't know a lot about both Node.js and python. Do you have a suggestion how I would get around that problem? Where is the lgtv.json file actually saved? I can't seem to find it.

I made it work. I noticed, that I run HAP-Node.js as sudo, so I reran auth with sudo and now it works :) Thanks for your advice!
