Ok, so I'm 95% certain I want a DOT3K but I just wanted to find out whether this is possible first.
I am currently using a RPi Model B as a usenet downloader using Sonarr and SABnzbd+. It is headless, so I have attached the Piglow and housed it in the Pibow Ninja case. The Piglow is set up as a system monitor, so each arm of LED's displays the status of the CPU, network traffic and temperature. This means I can quickly glance at my RPi and I know if everything is all well (normal status is 3 blinking red LED's) because sometimes the RPi crashes, so if I see activity on the Piglow I know everything is tickety boo.
However, I would love to see more usable information, hence why I'm considering the DOT3K. I would like to have the similar set up, except see more information - i.e. % CPU usage, network transmission in MB/s, temperature in degrees C and storage space left in either % or GB/MB. Maybe with other options, such as uptime etc.
Problem is, I'm no expert. The Piglow System Monitor is a code grabbed from here and I could figure out what I needed to tweak to get it the way I liked (i.e. which system stat to use, how frequently it should update etc.).
I have had a look at the DOT3K Github page here and noticed that there is a script (menu.py) which sounds about right to what I'm looking for, but I don't want to shell out on the DOT3K if it's dead in the water.
Looking forward to any feedback!
