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

[Des Westcott]

If it takes 0-10v analog signal then it should be doable. There were a couple of couple in this thread that have done it.

But then I'm sure you won't be able to use the standard Apex control plug to the QMaven Range. It's like a stereo headphone jack.

Hello,

I just purchased a reef-pi hat goby.

I noticed he also had a module for the Mars aqua. Would this work to control the viparspectra lights?

Thanks

I'm not sure how exactly Mars Aqua work, but by looking at this thrad:

My Reef pi build - Well, my Viparspectra PWM light controller :D

Where is your uln2803? That I think is your problem. You are trying to run the relays directly off of the raspberry pi outputs which draws too much current thru the pi output pins causing the undervoltage error. The uln2803 is part of the power controller for a few good reasons. It isolates...

www.reef2reef.com

Looks like Vipars are PWM out of the gate. The issue is that it needs a signal to turn on/off. I believe, and this is without a detailed look at MA light and Mike might be able to speak to this more, they operate in the similar manner.

So you would need something like a 5/12v relay which would get signal from the pie to turn on/off the light, then simple pwm signal from the pi or the PCA to adjust each channel.

I'm out of town for next two weeks, but I should have my replacement Vipar fixture by the time I get back and I can give it a crack then.

Thanks guys! When you said dipped in silicone I was thinking something comparable to Plasti Dip. I think the idea of heat shrink tube and seal up the edges with silicone it a solid approach.

My first one was the lighter weight sensor(not drox type). I potted the entire sensor up to about 1/2 inch of wire in epoxy. Still working about 10 months later. the next two were drox type and went into a freshwater tank with no extra coating.

Belated thanksgiving everyone. I was too busy wrapping up reef-pi 3.0 followed by thanksgiving food coma

I have installed a reef-pi outside in the patio yesterday to monitor outdoor temperature. It was almost 40 F last night. And its raining

Wify made hot chocolate

Now off to the next set of things. Son has a big agenda for the holidays... have to follow his lead here..

As the wise man said , happy wife == happy life

@ Ranjib I noticed a strange behavior in reef pi 3.0.

Is there a reload built in on a timer. Looks like my reef pi reloads on its own every night at midnight. It shows that on the about page and i can see the typical drop in memory usage that a reload brings every night near midnignt

We dont have anything built in that will do it. None of my build experienced this yet with 3.0

and

Theres are many things in linux/raspbian that can cause this. Can you run this and check what was happening during that time:

journalctl --since "2019-11-29 23:55:00" --until "2019-11-30 00:05:00"

Im getting nothing in the logs...strange

Any News to cut the Temp-graphs ?

hi everybody, just upgraded to 3.0 from 2.4. First thing i noticed is changements in Atlas ezo circuits management: my arduino is not responding the same way as before. (I use an arduino to emulate the behaviour of an ezo circuit through the i2c communication). Did you remove some character transmission from rpi ? I receive correctly all the "requests" from rpi but no more "transmissions" from rpi. Difference lies in different behaviour of Wire.OnReceive and Wire.OnRequest functions i am not aware of. However thank you all for your great work !

 

[hhaase]

Shoot, Ranjib, I owe you a bill of material on that hat I sent you. I'll get that done shortly. Same with a schematic.

I've got to order some boards for my business in a few days, so I'll probably be doing a fresh revision shortly. The funny part is I have two of mine built-up here and I haven't even tried either one yet. Haven't had time to do much other than get the base Pi OS installed. So if you've got any requests, now is a perfect time.

Im ready to upgrade to 3.0 but I am not sure how to backup the database.
I know its located at /var/lib/reef-pi/reef-pi.db but how do you actually do it?

 

[Bigtrout]

Not sure how familiar you are with linux but ssh into your pi.

First command changes the directory you are working in and is:

cd /var/lib/reef-pi

Next command copies the database into your home directory:

sudo cp reef-pi.db ~

Now you can go back to the home directory:

cd ~

Now check to to see if the copied database is present:

ls

If you did this correctly you will see a copy of reef-pi.db there in the home directory where you can leave it until needed. You can also scp into the pi and save a copy elsewhere.

We did quiet a bit of change in the device management layer, but nothing related to probe reading. I am running my a single build with ezo. Are you trying to do calibration? That can be broken , I have not tested that with 3.0. Use the python library for ezo to do out of band calibration and other operations. But you are saying this in not ezo, its an arduino.
It will be hard for us to promise ezo style i2c behavior from reef-pi. We will only use the reading features primarily, If your main goal is to make sure the arduino works across reef-pi version then emulate the reef-pi ph board protocol instead. Its a simple & minimal adc reading api without any calibration support.

[Blaxkin]

Yes to define a range. Maybe from 20 to 40 and all outside the range is not show.

Or is there a chance i can filter 85 and 127 readings in the code ?

This looks like a bug, but should not crash the controller. Can you share some details on the light setup?

@Bigtrout regarding to update the pwm profile of an existing light using API. here is the basic steps. The first few steps are common for all API operations

- Get an authentication cookie (equivalent to signin)

curl -c cookie.txt  -X POST  http://<IP>/auth/signin -d '{"user":"reef-pi", "password":"reef-pi"}'

- List your lights (we need the ID of the light we want to update. This should also show the details of individual light, including the assigned profile

curl -b cookie.txt   http://<IP>/api/lights

- Get json representation of a specific light (ID obtained from the previous step) in a file, so that we can edit the profile part and reupload it

curl -b cookie.txt   http://<IP>/api/lights/<ID> > light.json
[code]
- Open the json file in a text editor and change the parts you want. In this case the profile attribute. I'll detail the specifics of what to change little later. But once necessary changes have been made, update the light with  this
[code]
curl -b cookie.txt http://<IP>/api/lights/ID -X POST -d @light.json

Now, regarding your specific question on how to use the new interval profile to specify custom setpoints.
the interval profile requires an duration parameter that represent the difference between two consecutive set points in second, and a list of values each representing one setpoint. The interval profile like most profile has a daily start and end time and reef-pi will validate that the number of setpoints are exactly (start - end)/interval duration + 1. For example if start time is 9:00:00 , end time is 18:00:00 and interval duration is 900 (15 minutes) then a list of 37 setpoint values needs to be specified. Here is an example . I have reduced the start /end time shorter to limit the number of setpoints

{
    "id": "1",
    "name": "L0",
    "channels": {
      "0": {
        "name": "Channel-1",
        "on": true,

            "end": "22:30:00",
            "values": [
              0,
              16,
              30,
              52,
              66,
              45,
              30,
              12,
              0
            ],

          },

@Bigtrout this only crashes reef-pi right? Raspberry Pi is running fine otherwise? The error log here is cropped, if you do get the full log say from 23:58 that will be very useful.

theres nothing in 3.0 that has something like this. let me think through whats the best course of action from exact feature (moving average or some other type of smoothing) and priority perspectives. I need a few more use cases from others with similar issues. Worth tracking

I'd like a way of getting a smoother average graph than what I get below. If possible. Or another way?
