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

[Ranjib]

I'm pretty sure it's a bug. I'm not in dev mode and using my circuit but if mine isn't working Atlas isn't work, they both do the R thing. Seems to only happen with a fresh install of v3.4 meaning never had reef-pi installed previously, after getting it to work once it seems to always add. I'm going to go through more tests to try and pin it so you can replicate.



Thanks, I updated the setup manual where you add connectors and sorry for the confusion. The 12v is to power the DC ports for dosing pumps, ATO etc.

It's sad there's no other power bars available, I've been recommending the Kasa as an alternative. I set mine up like this so it can be connected direct to any Arduino or Pi pin and I can't believe nothing like this exists. I think it's a fairly big market, lots of people don't like wireless so why can't IoT or someone make a power bar like their simple little 4 outlet bar. If I had money I would get a board certified and proper case.

Not sure what you mean by 5v digital outputs? The DB9 outputs are only 3.3v from the Pi but the sensor ports are 5v compatible but work with 3.3v if you use the 3.3v on feeder port to power it.



Are you still having temp issues? Did you try another port in case I didn't solder a pin? They're all connected to same pin on Pi. If you still have issues maybe send me a message or start a new thread so we don't clutter this one.

The pH issue is an I2C clock stretching problem, the drivers for Pi for some reason don't support this so there's some sensors that will give errors. My pH uses an ATtiny85 and does this using the standard library. I put this in the install manual but forgot about the main manual, you can find it here.

https://docs.google.com/document/d/1noiBIzgaEX4cntBmgx2sJEPhMNCktRvF/edit#heading=h.s9sqlhjckqp

we should track the analog connector giving random value. I definitely want to fix it , if its present. It will be really nice if someone who have experienced it shares the detail so that i can reproduce it.

For all of you who have problems with DS18B20 reading such as 25.13 or similar, some sensor by default are set to 12Bit resolution. Following these steps you can modify that resolution to meet your need ;)

https://raspberrypi.stackexchange.com/questions/14278/how-to-change-ds18b20-reading-resolution
The Raspberry pi 2 guide works fine on a 3B+

3 independent thoughts.. maybe 4. Some of these maybe best for the development thread, but I forgot the link.. for that thread.. I think this was asked before.. but

1) can we develop a drop for anything that is clearly not an accurate reading? I'd much prefer that to the graph attached..

2) it would be really great to not have pH graph from 0-12.. custom range is fine. I can't really tell on the graph the level changes daily without mousing over it

3) has anyone automated water changes? I used a dosing pump from a saltwater and out to a drain.. when I activate it. It works well. And I do a few gallons at a time. It is slow.. a gallon an hour give or take. But takes literally no work at all.. so I'm thinking about running a few gallons changed each day from a 25 gallon tank. Anyone have thoughts on pros/cons on the idea

Finally.. I've been running reef-pi and following everything since like 2.2 last year.. seems like things are getting more active and harder to follow. Which is good and bad.. I'm excited about the progress and advancement. Guess that was more of a comment than question. :)

Thank you for taking the time and articulating your thoughts comprehensively. I'll make sure we address the ph chart range issue in 4.0, as part of the braoder UI/UX improvement work. I am still on the fence about discarding error nous values from sensors. I want to implement a moving average based robust mechanism for filtering, and not an arbitrary threshold based (certainly not one where we set the default).
For the last observation, you are right.. its a challenge with growing project. We have to do a better job around documentation and resource navigation.. and take it from there.. constantly incorporate feedback from beginners and experienced users and augment them...but again this will be harder as the project gets more adoption and maturity (more features).

Thought I would post my progress on controlling viparspectra lights with moon lights. Big thanks to @Michael Lane for making and providing a board to make things plug and play, more detailed information can be found in the controlling viparspectra thread - https://www.reef2reef.com/threads/controlling-viparspectra-lights.698216/

Here are some pics (vipar lights, they are bright, white @20 and Blues @60-

Moon lights @10%, the appear brighter in the picture than in real life, you can go all the way down to 1% and they are barely on, will use these to ramp up to the vipar and ramp down after the vipar...woot!

:)

I got my robotank installed and started playing over the last few days.

so far just using 3 temp sensors and couple DC outputs for led work light in sump, fan (in temporary while I wait for a hole saw from Amazon) and RO solenoid.

Everything else connects via 2 HS300’s.

Rest is in my build log, but couldn’t resist posting my orange controller to contrast @Ranjib’s green one :) (green looks slick btw)

Updated config.txt ref clock stretching, hopefully should do the trick.

As for temp, since I switched to a fully siliconed probe the issue is "fixed"...at least the symptom. I tried plugging the non-siliconed probe in and it works fine until it goes in the water. I tested for stray voltage and not seeing any on my Fluke DMM. I don't think it's a controller issue or at least maybe not entirely. It either gets voltage or interference. I made sure to keep probe wire away from any AC/DC wires. Going to silicone the "unshielded" probe and see what the result is.

These are the probes:
https://www.droking.com/2-PCS-LOT-D...ensor-55-125-Celsius-Degree-Thermometer-Probe

Those look like nice probes, I'm going to look into getting some. These other cheap ones, I thought you had, are hit or miss. I wouldn't think but wondering if it's something with the shielding and covering the metal would make it like no shielding touches the water. I know some people have used a grounding probe to solved issues like this, maybe test with a bare wire to see if it goes away.

we should track the analog connector giving random value. I definitely want to fix it , if its present. It will be really nice if someone who have experienced it shares the detail so that i can reproduce it.

I'll definitely make up an easy step by step so you can reproduce, just a time thing right now as I need to reformat SD, I still haven't figured how to "uninstall" reef-pi lol...

Looking good, I think the green looks better because of connectors, now I need to find orange, blue, red...

Did you add a switch on the door to turn off the light?

Almost all values in ranges moves from x to x+1 or x-1... maybe x+2 or x-2.. percentage based.. it should ignore and maybe report or error an x+2000 single value.. or an option.. skip recording that.. until it's within range or repeats 3-4 times.. just a suggestion.. I know as a programmer that the logic is never that simple.

Thanks for all that you do!

I think we can all agree that the relative odds of the tank being -3000 degrees is pretty slim.

That's the weird thing. When you leave them bare metal (contact with water) is when the issue happens. The one covered in silicone seems to be working so far.


Might try grounding probe. Would a simple wire from ground in the outlet to the sump work for test purposes?

Just noticed I'm getting these errors. Yet everything seems to be working fine. Any idea what could be causing them?

How’s the cpu utilization chart ?

 

[Schreiber]

At the moment, reef-pi only has a driver for ADS1119, through the ph-board implementation. I don't think the ADS1119 is readily available on breakout boards, so that's unlikely the be helpful.

On the other hand, I plan to have a driver for ADS1015/ADS1115 ready next month. Those ADC chips are pretty common on breakout boards and should be able to support the TDS module you linked.

I actually got one of these TDS sensors on a whim in an order from DFRobot a few weeks ago. Haven't had the time to play with it yet, but let me know if there's anything you'd like me to do or test!

Starting to get a little frustrated, grumble, grumble....Looks like my existing reef-pi unit that has been running for a year plus corrupted the SD card, I really don't like SD cards. I took this as an opportunity to rebuild with the latest version, easy enough and I got it back up an working, using 3.4. Either I have run into a bug or I am doing something wrong, but I get a portion of the way through configuring and if I reboot the service will not start up, here are the journalctl lines:

I have enable prometheus and haven't tried turning that off but something is amiss here, I can always drop back to 3.3 but I see a panic and an invalid argument error messages. It will not start up, I thought it was my naming convention or something but I think something is amiss in 3.4 that's not very nice.

Let me know if you need additional information, I will delete the database once again and see if I can figure out what it doesn't like.

:)

UPDATE: I've narrowed it down to the temp sensor readings, it crashes right after trying to read the temp value, doesn't make a difference which temp senor is enable it crashes after trying to read the sensor:

2020/05/28 23:59:45 Reading temperature from device: 28-011938443c3c

If I disable the temp sensor it stays up...what am I missing? I've enabled 1-wire and I2C in raspi-config, and it sees the sensors but is crashing non the less. If anyone has any idea's let me know.

Thanks

 

[peejay]

That’s not a deliberate move. We updated the charting library to address some deprecation warning, I’ll cross check .

Hi,
Did you manage to find anything related to my issue? I have re-installed Reef-Pi twice now, the last time on a new card with fresh install of Raspbian but I still get the same effect, no red bar for "Off" but green bar for "On" as normal. Also, I have a temperature graph on my dashboard, it no longer updates until I hit Reload so data is there but no updating on the graph.
Thanks.

Yeah that would be ok.

Also check if the shielding is connected to the metal end and if ground and shield are connected.

 

[Des Westcott]

To be perfectly honest, I turned them off. I've enabled them again and will monitor.

Starting to get a little frustrated, grumble, grumble....Looks like my existing reef-pi unit that has been running for a year plus corrupted the SD card, I really don't like SD cards.

Thanks

SD cards aren't hard drives.. huge weakness in the system..
Too many read/write cycles..

 

[Yov]

So i have another question... In a Paludarium i would need the humidity to be 70-80 during the day and 100 during the night...

So during the day i would set the humidity control with the PH settings : Upper treshold would activate a fan when i reach 80. Lower treshold wil deactivate the fan or wil activate a humidifier when it reach 70. hysteresis 2-3.. (i have to experiment with this)

But when the night fals i need to get other settings. to reach 100% humidity. How can i approach this? do i look at Macro's ?

 

[Badfish2too]

Well really it only experiences "wear" when it is turned off and on really. When it is left running, it is all in the RAM. A lot of major companies rely on flash storage for the OS of virtual machine hypervisors. Myself included. You could always set up a SSD or external drive and use that instead
