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

And I have connected a Servo that I am controlling with the light tab, it works in manual mode from 50 to 99 only it turns about 90degrees in total. Is there extra support needed like a driver ore some additional programming? It will be nice to have, to build a feeder with multiple servos that turn to deposit food in the aquarium.

I believe someone has already written code for an autofeeder. I do remember seeing it in the additional resources at one point.

I can't seem to get my (standard raspi) camera to work in 3.0.

dmesg shows success:

[ 7.727495] bcm2835_v4l2: module is from the staging directory, the quality is unknown, you have been warned.

daemon.log shows:

I'm not sure why it goes back to "Starting" after it was successfully started, but the UI just shows:

Something went wrong.
TypeError: undefined is not an object (evaluating 'i.props.views[i.state.currentIndex]')

The camera worked well in octoprint, so it should be in good shape.

Question on temp probe calibration.

I just noticed the feature and gave it a try. I dropped both probes in the same spot and let them sit for 10 minutes and they where 1 degree off from eachother. I used my BBQ instant read for a 3rd reading which matched say probe 1. I then changed the calibration value in probe 2 so that it matched probe 1 and put them back in their spots. When I went to go look back at the calibration value it was gone. Did the calibration save and just does not show? If so how can I reset to defaults since I dont remember which probe I adjusted lol.

I have to break it down to smaller pieces and process :-) . I can double check the calibration behavior , but I think I will add some ui data to indicate existing calibration data by 3.1

I think you should just redo the steps :-) ,If you didn’t see any error it likely means the calibration data is saved .

reef-pi should display the temperature calibration point if you open the calibration dialog again. I've just double checked the UI code to confirm. It's possible that we have a bug in that behavior though.

It won't hurt to calibrate the temperature probe again as Ranjib suggested. Can you tell if the probe is reporting the temperature you expect? I also looked for anything we might log during temperature reading to indicate a calibration adjustment, but didn't see anything. Maybe we can update the logging to print the raw and calibrated values.

Hi Ranjib,
Good work with the launch of 3.0!!!
I found a little thing maybe you can update it next time:

When a driver is created for PCA9685 the Frequency is not showing if you want to modify. Maybe that was on purpose, can you at least show the set Frequency along with the name and address? It will be nice as well when you can change the Frequency and save instead of deleting the driver(and everything that is connected to it) and creating a new one.

Yeah, this is a UI gap that we have to fix. The driver UI still does not have the ability to provide driver specific settings (frequency in this case). If it helps, i can provide API equivalent,

Yes please, then I can play with the frequency... LOL

Alright, I guess alternative is to use an ATO container that won't overflow the sump if ATO gets stuck.

I run a separate fail safe independant from Reef-Pi to kill the power to my ATO-related items in the case of a high sump level. I run it at about 30mm higher than my normal running level, so even when I turn my return off it disables ATO pumps.

The ATO's are obviously still thinking they are working under Reef-Pi, but the pumps aren't getting power. This way I get a usage alert as a notification that something is wrong.

Would you mind sharing more details on your setup?

Dewd's Big Cube Reef-Pi build

Hi all. I have recently decided to upgrade my small nano (200l) to a new "cube" that I got at a phenomenal price Tank size is 800mm(W) x 800mm(L) by 1000mm (D). Water level at about 900mm deep. (31 x 31 x 39 inches) Yes, yes, I know all about the challenges around deep tanks, but I've...

There's my build thread

 

[Des Westcott]

But basically all my "ATO pumps" are 12V.

I have 1 x 12V peristaltic pump that pumps through my kalk reactor for top-ups and 2 x 12V pumps for my Auto Water Changes. So I have 3 x 12V channels on my bank of relays.

I run this 12V supply to these 3 x relays through a separate relay board (Independant of Reef-Pi) that I trigger with 5V (taken off the 5V supply to the Pi) from a separate float switch set at the high level in the sump.

I hope that makes sense to you all.

My original PH probe was kicking readings that were all over the place, so I ordered a replacement and different brand.. works perfectly now! Thanks to all on here for the help...

Is there a reason the scale of the graph isn't more like temp where it will make the graph high to low readings as opposed to 0-12?

What brand was causing issues and which worked fine?

This one is the new WORKING one.

Amazon product ASIN B001EHJO64
The original NON working one was this

Amazon product ASIN B00C2DVAWU
But in all fairness, after getting the new one which came with a wet container that was removed before use, after some reading, the original didn't have one, and came dry but probably should have had one. it may have been a previous return that never should have been shipped back out.

The Y axis limits are currently fixed in the code. We are thinking on how to make this configurable. Me and Michael discussed about this. Expect something to address this problem in generic manner across all charts.. Not sure when we'll have the exact time, but its high on my radar. We are shipping macro reverse, ATO controllable macro etc for 3.1, which i feel is of high priority.

More than likely was a return. My Milwaukee ph probe came in a wet container and has been working great. The instructions say to put it back into the wet container with ph probe storage solution when not using.

My probe was this:
Milwaukee Instruments MA911B/2 Double Junction Ph Electrode with 2 m Cable and Gel Filled Electrolyte Solution Amazon product ASIN B0009YJ22O

Yeah, if the probe is not in sealed buffer , it’s likely to be unusable

Reef-pi does not have servo or stepper driver.it can only generate pwm signal .i do have plans for stepper driver (for dosing pump ) in future

Hi dear reefers
Just DL latest version of reef- pi, and trying to set up heater control. But getting this message Hysteresis value must be provided. Can you explain to me what to type in this box. I do not understand the meaning off this box :)

Best Regards
Michael

Hey. I struggled with this as well, and found that if you put in a random chiller threshold and a phantom outlet the problem goes away. Can always edit the boxes to the correct ones when you get to setting that up.
