    Let me check out the details and get back to you
  2. JUST ANOTHER reef-Pi BUILD, Dec 10, 2018 at 4:20 PM

    Yesss :) . Thank you :) . Now we can have all the details of your build in one place. Do you have reef-pi running ? #reefpi

    Wow, I am finding this thread right now. #reefpi
    Awesome :0-) . So you have not connected any relay/powerstrip yet. Will wait for the scratch built relay updates.
    Very clean build . I like the driver choice for the dosers. Keep us posted.

    Ok, I am revisiting this as I have learned a lot since I reported this, and I think others would find it useful,
    After @Randy Holmes-Farley pointed out this can not be correct, I went read some of his prior write ups and also some technical documentation about pH probes. I was not using a voltage isolator along with the pH sensor circuit, without this the sensor reading are prone to aberrations from stray voltage, from tank or from controller's internal circuit. I didn't panic after the initial findings as my corals were OK and there was ample advice in this forum to not chase pH without understanding whats going on.

    Couple of days before I have added the recommended voltage isolator in pH sensor circuit and that address this issue. There were two noticeable difference, first, my tank pH suddenly jumped by 1, earlier it used to vary from 6.6 to 7.7 and now it varies from 7.6 to 8.2 . Second , the ph readings do not show a jittery curve any more, they are smooth contiguous readings. Here is a chart showing the changes from past two days

    I have orderd a separate pH testing kit as well, to validate the readings independently. But I think I have dialed it now. #reefpi

    If I understand correctly, BRS dosing pump is like any other AC equipment and timers are used for them. reef-pi already has timers, so the dosing pump will be connected to the american DJ power strip and timers will be created to in reef-pi to automate them.

    reef-pi has built in dosing module as well, but thats bit different, more like other commercial doser where you get to choose speed, frequency and duartion of the dosing process
  10. Raspberry Pi incorporation with tank?, Nov 10, 2018

    Thank you @TheEngineer :)
    @IzzyT3 reef-pi is an opensource reef tank controller based on Raspberry Pi, capable of doing powerstrip (AC equipment) control, daylight simulation (kessil and other LEDs), ph monitoring, temperature control and various other things. The thread @TheEngineer mentioned has detailed guides in the very first page, that should help you get started if you are interested. The thread itself is used for ongoing reef-pi development as well as any help others may need in their build process. Feel free to ask questions there or start a build thread or just use this thread to ask questions if you do decide to build a reef-pi controller or test it out. There are quite a few folks who have now reef-pi controllers so you'll surely get help if you seek, just tag #reefpi

    Running a forum site is a lot of work :). We can do a google group or something. But then there's another aspect to it, which is staying close to the cause, I don't want reef-pi to be a tech-centric thing. Its focus is to ease reef keeping, and having the discussion here helps with that cause. We have an opportunity to learn the best reef keeping habits and address the most common challenges here by being with the community.
    That said, I'll link the important posts in this thread to reef-pi website as a separate blog. I don't think it will be hard to just create dedicated threads and builds, we can group them with #reefpi tag. If the original authors are not interested in it, I'll take permission from them and start those. We can sticky those links in the very first page of this thread. There are a lot of other tricks we can do to address most of the current challenges, here in r2r, where the community lives.

    @reefsquared let me know if you need any further help with this

    Curious if this is in operation, #reefpi
  18. Reef-Pi ATO and Auto Water Changes, Oct 11, 2018

    I don't have an example handy, but it should be intuitive. If you can mentally break down the water changes into several steps, we can then come up with the list of steps in a macro. I use something like this for my nano tank, create two macros, one to being the water change and the other to finish the water change. I do not use reef-pi to pour the new saltwater mix, since I use bucket and perform pretty thorough cleaning (like blowing crevices, trimming corals, plucking unwanted algae sometimes etc)

    WC Start macro steps,
    - Turn off ATO
    - Wait 5 seconds
    - Turn off Return
    - Turn off MP10

    WC Done macro steps
    - Turn on Return
    - Wait 5 seconds
    - Turn on MP10
    - Turn on ATO

    The macro UI is still bit in-progress, we'll polish it up before 2.0 release
