I figured out that after some hours fibaro gateway become unresponsive.

searching the cause of the problem I discovered this:

and so many many other lines..................

This bug is caused by a scene like the attached screenshot.

Moreover the problem is accentuated by overlap of the triggered scene (each time the motion sensor become "safe" the scene timer start). In a future release would be great if I can enable a check into scene programming to make certain scenes to "run only once at a time".

Let's me know if do you want major details.

Thank you very much for the support.

Best Regards.

Thank you for detailed description of the problem. We already know about it and we are working on new engine of executing the scenes. For now I can't tell what's the deadline, but it will be a huge change. Scenes will work / devices will respond many times faster than they do now and cpu usage will be highly decreased.

im not sure if it is the same but seems so, when i use many scenes then HC2 becomes very slow. would be happy to provide more info for debugging!

EDIT-turned off all scenes where timers where used and HC is fast again:)
