Hi Einstein.42,

Sorry to bother you again with this. However, the script stopped working again. Below is the error log. Could this be the API again?

 

Thanks for any help.

Yeah, try something like this

Got the pull request done (I'm pretty new to git, using SVN at work) so please review. I've also added my "token caching" functionality so authentication is not done on each request, token is now cached in the temporary file for the amount of minutes configured in the TOKENTTL variable. That should reduce load to MyQ Auth server and mimic the real app better, plus people should be able to pull the door status more frequent (but I still agree that 5 minutes is a good interval, if realtime update is desired - use door sensor instead).

Thanks xKing. You are awesome!  :-P

 

I will let you know as soon as I entered all the needed information to integrate with my ISY. I am using io_guy's nodelink relay server. So the config.ini doesnt work for me.

 

This might be a dumb question. Is the ChamberAPPID still this --> NWknvuBd7LoFHfXmKNMBcgajXtZEgKUh4V7WNzMidrpUUluDpVYVZx+xT4PCM5Kx or your modified script automatically pulls the new APPID?

 

Sorry for being a newbie :)

Well, find the line

config.read('config.ini')

and change it to the absolute path like

config.read('/home/pi/myq-garage/config.ini')

so you could still use the config.ini 

 

App ID is still the same and there is no way to figure it out automatically rather than trace what real iOS or Android app sends.

 

P.S. Please use "git pull" to fetch the updated version from the git hub, disregard the zip file please.

Hi xKing and einstein.42,

I just want to update both of you that the new file from github works perfectly.

 

@xKing, thank you for letting me know how to use the config file. It works now as long as I include the full path.

 

Guys, I've learned a lot from your codes. Thanks again for sharing this.

 

Great work!

sounds like a permissions problem? how does /home/pi/node/logs/myq-garage.log file permissions/ownership look like?

 

could it be that you've run it as root one day so the log is root owned and can't be written by the "pi" user?

Hi xKing,

I changed the permission owner and group to pi per your instruction as well as the permission to 0755. Below is the error message from the log.
