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

Ok this is what I came up with,
Amazon product ASIN B08JTDJXLY
I think this should work to make a anolog voltage signal for t5 lamps from a PWM signal. Ill give it a shot in atempt to control t5 bulb brightness

Looks like it should work, that's as close to an all in one package you'll get. In reef-pi set the frequency of the PCA9685 above 1000 Hz as this say it wants 1000-3000 input. 1526 is the limit for PCA9685.

Hi:
After my Digital Aquatics Archon finally gave up the ghost a few weeks ago, I switched over to reef-pi on robo-tank hardware. I've got my LEDs driven by a 0-10v signal on a diurnal program that has them come on at about 2:30PM, and then go off around 11:30PM. Because a couple of my LED drivers don't always completely cut off, I've also got 2 AC outlet switches that are off from midnight until 2:00 PM. All this works fine and it's the way I had it set up for the last 5 years or so.

Sometimes, though, I want to turn the lights on in the morning, maybe for service, or maybe just to see what's going on. On my Archon, it was easy to set up a macro to do this, but I can't seem to find a way to do that under reef-pi. I tried creating a manual lighting program that I could enable and then turn the lights up. But it seemed as though every couple of mins, the main program would turn them back off, then they'd come on again...

How can I set up a macro/timer/something to turn the light on manually?

Thanks,
Phil

Hi Phil, as I mentioned I tried to get something like this working but got the same results as you, maybe someone has an idea to try?

Do you think that will cause any problems with dosing pumps?? I'm also going to run pumps off of the PCA9685. That and led lights

If you're driving a mosfet or something similar for dosing pumps it should be ok at any frequency, you'll likely see a slight difference at the lowest levels. If you run the light 0-10v module under 1000 Hz the light may start flickering, you'll know if there's an issue but everything should be ok.

I had a similar issue, I run one light off of the 2 pwm channels of the pi itself and other stuff on a pca9685 on a different frequency

@Ranjib Until recently my ATO has been working fine. Now when the (optical) sensor is reached each time it disables all ATO module rather than just turning pump off. Any suggestions?

do you have one shot enabled?

Hi @Ranjib

I'm Hector Espert: https://github.com/hectorespert, the author of these pull requests: https://github.com/reef-pi/reef-pi/issues?q=author:hectorespert

I'm building an aquarium controller for my planted aquarium using the reef-pi project and I would like to help to continue developing that.

I was wondering if I could be a member of the reef-pi github organization to obtain write or triage permissions to help with the development.

thank you for the code contributions @hectorespert . My sincere apologies for the delay in triaging those PRs. I just went through those, merging the ones that are good to go. So we should be good on that side.
I have granted the organization membership to only @Zekth and @Michael Lane for their sustained contributions and active participation in the development discussions. For your inclusion in the github org, I'll recommend focus on the same and we'll come back to this soon I feel comfortable (its mostly around trust, which comes from tenure/consistency). I'll also have to reach out to zekth and michael for their state of affairs, 2020 has been crazy for all of us, would be good to consider their thoughts.

Hope this answers your question,
ranjib

if the optical sensor itself is mis behaving (i.e. not changing state when water level drops) then theres very little we can do from software side , other than stopping the ato pump after certain time.
I had bad experience with the optical sensors, hence switched back to float switches for my recent builds.

me to , I had the optical sensor give me issues, two back to back switched over to all float switches also

Ok, so I am trying to fire my reef pi up after some difficulty working it the last time. It has the Saltwater Advanced Leviathan board on it. I have the power strip working awesome. I hook up the temp probe for temperature control, it took me forever to get it to recognize the probe, literally took three weeks and I finally got it to see it today. When I plug it in however, I set the check intervals for 10 seconds, save, reload. Then I goto look at the temp graph and it says 0 degrees Celsius, 10 seconds later, 32 degrees Celsius. It continues to do this to this moment. How do I fix this, my room is not 32 degrees sooooo...........yeahhhhhhh, can someone tell me what I am doing wrong?

Does the temperature change when you take the probe into your hand for a minute? Maybe you just got one that is particularly wrong, they all are a little bit, you can calibrate them in the temperature menu of the reefpi ui

The 0 is "normal" when you setup a new temp probe

 

[Coolhack]

Temp doesn't change at all except from 0 to 32 then back to 0 and 32. If I calibrate it, say like to 72, it goes from 72 to 39 and back to 72 then back to 39 the back to 72

That doesnt sound good, do you have multiple temp probes? Maybe try another

They all do the same thing. I have even made my own board with the same results.

Any chance you don't have a 4.7k pullup resistor on the data line? Never heard of such results but maybe no resistor would cause that.

I have it on the data line on one board I built. But I can't get the temp probes to work on the Advanced Saltwater Leviathan board either. I have spent like 39 dollars on probes and none of them work right. I just don't get it. I am using a raspberry pi 4 with 4 gigs of ram and a 64 gig memory card. Power strip is the ADJ SRP8. Everything else works fine except the one thing I want to work, the temp probe. I just don't get it. Have hung up the project like three times now because the temp probes won't work.

Probably a setting somewhere. Try reformatting your SD card, install Raspberry Pi OS again then use this script I have to install reef-pi. There's a few settings on the Pi that need to be setup for reef-pi to work, my guess is that's the problem. This script will take care of all that. Near the end it will ask if you are installing for Robo-Tank, select No so you get the default reef-pi database.

You can just try running the script first to see if it sorts it out but if you've already edited config.txt it probably won't work properly.
