Reef Pi? Can it....

[Dmmuir]

Here’s a question. Can I build a reef pi to control many pumps? All dc. Not all the same brand. Say I had a dozen various dc pumps?

Build an enclosure with a bunch of 3 pin connectors as an all in one controller?

Yes

reef-pi can support a bunch of relay controlled outlets. It can also support multiple PWM outputs (which can be converted to analog signals 0-10v). Each pump may have a different control mechanism, so you'll have to do some research for each one to understand how it works.
