Customizable powerhead/wavemaker recommendation

[keddre]

I'm looking for a power head where I can (in order of preference):
1) I can have it turn on for 30 seconds every two minutes.
2) Can program from a Linux PC
3) During those 30 seconds have it start at 20%, "gradually" have it come up to 100%, then "gradually" come back down.
4) let it randomly change the peak. 20%-100%-20%, 20%-75%-20%, 20%-80%-20%...

Current makes the programmable eflux powerheads. Not quite sure they have the level customizable options you're looking for though.
