@klaasnicolaas: I suspect you uploaded a new script over the old file? That has changed the permissions of that file (the owner), and now Domoticz is not allowed to open it anymore. You can try to change the permission settings of the file. Right-mouse button on it from linux. Of use the terminal ...

If I test your script in my environment, I get this: Traceback (most recent call last): File "check_device_online.py", line 80, in <module> open(pidfile, 'w').close() IOError: [Errno 13] Permission denied: '/run/check_device_online.py_192.168.2.7.pid' I don't understand how to solve this, could you ...

I think that a lot of people loves this function Makes it much easier to organise your own dashboard.

Great work Rob!

Nice that it has been solved

Thank you Raymon that does the trick

Whatever you could do is looking for the latest dashticz V2 update.

No that is not necessary.

I ask because I have also a problem that is similar to this.
I don't see my switches if I'm not logged in to domoticz. So before I see something in dashticz, I need to log in from another tab (browser) in Domoticz. Very annoying if you still have to do that.

Have you secured domoticz with a login / password?
