I was thinking of something like that. Maybe you can send via the USB some formated informations resulting from, for example, a TOP or PS shell command. Maybe csv like formated data, then your setup tool can just translate those data into displayed infos. I see this like this is you setup : - The command to be executed - The data format - The result on the screen - The refresh interval Very good question : I think that 4 fans sensor and 4 analog (share for temps, voltage, etc.) could be nice. I think that it could be a nice addition to be able to create a sensor lib. This will allow advanced user to create their own sensor and set the "attributes" (voltage range, etc.) depending on, for example, the termistor used to sense a temperature. Outputs ... I really have no idea. For sure a LCD/VFD output.
