    Hello Bay Are Reefers,
    I am excited to announce the immediate availability of first public release of reef-pi, a DIY opensource reef tank controller based on Raspberry Pi. Over the past one year reef-pi several community reefers have built and provided valuable feedback to improve this project, and currently it offers following features
    1. Equipment control (power bar) and timers [upto 16 outlets and any number of timers]
    2. LED light control (day light cycle)
    3. Auto Top Off (using photoelectric sensor or float switches)
    4. Temperature control
    5. A dashboard of all the above-mentioned features and alerting.
    Following is a screenshot of reef-pi dashboard

    Detailed build instruction and documentation can be found here: http://reef-pi.com

    If you ever want to build an Alkalinity-Tracker into that, send me a PM.
    Not a direct alkalinity "measurement" per se, but something fairly crude that tells if your Alk goes up/down too much.
    Which is really all you need.

    Back when I was on a DIY-Controller kick, I had a decent plan for one, but never got around to it.
    Of course, plan != working.

    I'll keep you posted. I have pH, doser, wave maker planned up for 2.0 release (will have two milestone, 2018 Makerfaire & X-Mas). Then I'll try to take a stab at Alk, I know certain ways to do that, but I need the doser module nailed first. Alk/Ca monitoring will involve automating the titration bits, which in turn involves a doser/peristaltic pump. I know we can get a hacked up version going quicker, but I want to be throrough, come up with something reliabile and maintainable, and back it up with proper docs and bill of materials.Hopefully the community will also grow a bit more by then.

    Out of curiosity how are you detecting/changing(?) power cycles on your equipment? You say power bar, but is this just one of the "name brand" (Neptune, etc) power bars that you hack with the Pi?

    its a DIY powerbar. Which is basically a wooden housing with bunch of receptacles mounted and a relay. The realy in turn is controlled by Raspberry Pi. The reef-pi software provides timer functionalities , and temperature controller style equipment on/off

    That's super cool.

    Well except the "wooden housing" for your power bar? That's a big no-no.

    Yeah, I need to do a better job for that housing. I am thinking of modding a triplite power strip with individual switches.

    I have used the single outlet version of these. They are good. But very inconvenient, you'll have wires connected to them. The single ones are particularly interesting, you can stick a 10$ pi zero and have a controllable (digital timer, web interface etc) outlets.
    The one that @Mark B suggested is better. I am looking for something wallmounted/hob style.. not something that i can mount inside my stand., since its relatively small, 29G biocube stand.

    I am not very sure if its too risky for me. My tanks are nano or pico, and I really dont have way too many equipments. Each tank is powered by separate outlet/powerstrip al together. Some equipments (like LED) are not at all connected to the controller unit. I am looking for mostly DC equipment in future (like dc returns,wave makers etc), and I think I can just do away with something similar to a compute SMPS.. we'll see. for the time being something similar to what mark shared is my first choice. I am hacking with this one, as we speak

    Thanks for the offer :) . If you are interested, I'll be giving away at least couple of reef-pi builds during 2018 maker faire.

    I have a dremel, a scroll saw, few other tools (drill bits) .. but my challenge has been to find a powerstrip inside which i can mount a 8 channel relay. Something like this: https://www.sainsmart.com/products/8-channel-5v-relay-module
