reef-pi :: An opensource reef tank controller based on Raspberry Pi.

[GaryE]

Not the prettiest install, but it's highly functional.

It takes hours to clean up, but seconds to destroy.

if the remote sensor has a wifi based api we can easily integrate. Its also possible that we can have reef-pi hal driver that will allow using one reef-pi's sensor data to be consumed by another reef-pi.

Cool! I was thinking this https://www.ebay.com/i/133209331811...Ub6SXDlbZpsqMvc6WyqyfcCn1TUytqbhoCowIQAvD_BwE

Seems to have mixed reviews related to wifi being only 2.4ghz... but its cheap and might be an interesting option for AWC from the mixing station. (like what BRS are doing with Neptune DOS setups).

I could see using a 2nd reef-pi though and somehow linking the two, that would be cool. For example using the tank's reef-pi sump sensors to measure levels, but have dosing pumps at the mix station and also monitor levles of the reservoirs.

I have a Bubble Magus sitting the old-stuff pile; need to get all that stuff a new home. What I found works the best is Atlas dosing pumps, work like a charm for me. I cannot do this closed and proprietary stuff anymore...I am sick of dissecting it with my logic analyser and making a mess!

I just assembled my raspberry pi and installed reef pi and now I'm looking to make the power controller and I was wondering if there are any cheap alternatives to this power strip CLICK

I built my own from a $20 power strip and some relays. With my labor factored in, it cost me about $300 to build.

That $50 power strip is cheap.

Haha amen. By the time I built my powerstrip, factoring in my time plus supplies... I would have gotten off cheap buying an HS300 lol. So for my second powerstrip, I did buy an HS300.

Dido. I just did both options, I bought one SR8 and made one custom relay 8 channel pack. By the time you buy the relay pack, db9 connectors, plugs, 3D print an enclosure (assuming you have an enclosure) you’re almost 50 bucks in and all you have is a box of parts at that point.

Wait im confused. So in the original post on adafruit it said we need a breadboard but in the power controller guide it says we need the hat. Do we need both? I already bought the breadboard.

i think its on the cheapest range in off the shelf category... its quality is not that great. We have had defects in many cases.. Even if you build from scratch it will cost more with new parts (outlets , relays etc). If you have those parts, or find them by other means (i had gutted an existing surge protector when i first prototyped..) that would be cheaper.

the first guide uses the breadboard for testing initial setup and demo/dry run. You can run reef-pi with breadboard, but its not safe or secure (physically). Since most builds expected to run for years individual guides always use hat or proto boards.

 

[youngreefer10g]

Cool! The hat on Adafruit is sold out any other options?

I've just reset alert time again and ran and got nothing (after 16H00). No alert or disable

I'll be checking again the ato alert, but last i did i was not able to reproduce this.
My ATOs are running ok as of now .

@Ranjib posts coral pics to lighten the mood in this thread.
I have some neat news. A pair of angelfish successfully spawned and hatched eggs in my community tank! Dont know what to do. Let them be and nature take its course or try to move them to the empty section of the sump.

Oh wow :-) . Congratulations. My son will be super curious to see these tiny fishies .. i'll show this to him first thing tomorrow :-) . Thank you for sharing

 

[Des Westcott]

Yes.. it has to be a bug if its reproducible. Can you share the details like check period and alert threshold for the scenarios where its not working consistently? We discussed this earlier and I was not able to reproduce it with my setup. I was using 5s check period.

Just ran this as another test. Ran for 180 seconds with no alert or disable.

 

[Ranjib]

ATO issue - It seems that reef-pi gets to the limit of alerts in an hour and then when the clock resets at the top of the hour it sends out alerts from the previous hour that weren't sent. Since my last post, I have been recieving 10 alerts every hour, on the hour, but they are comparing previous usage to current alert usage limit.

I don't have the ATO Disable on Alert , because I want my ATO to keep working.

So.. "disable on alert" is working? the usage thing is a known bug. I'll get to it soon. Im trying to consolidate the ATO issue.. i definitely want to fix it asap, but having a hard time compiling it. Let me start a github issue.. where we can add the details

Wow... thats not good. Do you have macro or anything that will enable/disable ato?

No. I set it to Alert and disable on alert at 20 seconds and the ATO ran for 180 seconds with no alert and it did not disable. Same as @ahnuts72 describes.

My only macro that affects ATO is my AWC Macro and that is definitely not running at the moment. I actually even have the timers that control those Macros off at the moment.

(Due to Lockdown conditions I have a limited supply of fresh sea water and am triggering them manually)

Hi @Ranjib - I'm having trouble getting my PH probe set up and was wondering if you had any idea as to what I'm doing wrong.

I'm using Michael Lanes reefpi gobi hat with a PI zero. As for PH I'm using Atlas's carrier board and PH module.

I got it set to i2c (blue light) but when I go to the PH tab and hit the add (+) button, there is nothing showing in the Analog Input dropdown.

Any idea?

Also I have o errors but this shows up when I first load the page, I think it's because I dont have anything configured on myy dashboard yet. {"error":"stats for id: '1' not found"} | HTTP 404

you have to use python ezo library from atlas to configure the ezo circuit in i2c mode. By default it uses UART, which reef-pi does not recognize

 

[Ranjib]

No. I set it to Alert and disable on alert at 20 seconds and the ATO ran for 180 seconds with no alert and it did not disable. Same as @ahnuts72 describes.

Got it. Can you disable this ato and create a new ato with same setting and see if that works? Im trying to diagnose if this is related to the past usage data or some other thing.
