If I understand correctly, we should be able to do it easily. As of now, reef-pi allows two ways of configuring LED channels. Cycle and fixed. In cycle mode reef-pi uses the 12 values (each at 2 hours interval) to mimic day light cycle. In fixed mode each channels are set at a fixed predefined values. If all you ever need is a single preset for viewing pleasure, this should do. But if you need multiple presets and choose one among those, then I have to add some code. Should not be very hard, but given the limited use I would say it will be of low priority, after ATO & Doser

. I need those two for my sps well being. Also camera module. I just realized I have a vacation coming up.... I have to get the camera module running to take photos periodically and upload them in imagur or something similar.
I wish reef2reed had an API. We could have had automated tank journals.. where reef-pi would upload the photos and parameters, and we could add some ancillay details.. have discussions etc..

. How cool that would be.
