Addon Dev. Question - Action on Pressing Power Button?
Hi. In response to a request for an addon that does more with the NV+ front panel LCD display I have started work on an add-on. So far I have created a shell script that produces various outputs to the LCD, which works fine when run manually (or via cron) from a SSH session with the NAS. I have been reading the addon SDK guide and want to know how I can change the behaviour of "user presses blue power button" with an addon...?
Otherwise I will just have to make an addon that periodically displays sys info e.g. every 30 minutes.. Which is less useful.
For info, here are some sample ""screenshots"" that the script does with the LCD. Any feature ideas are welcomed but please have an idea of how it could be implemented!

Nah I never got around to it. But I did write this script, if you want to use it and put it in a cron or whatever... No warantee provided. YMMV.
