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

you dont want to test the probes before mounting? What are the three probes you are considering?
Looking good

I would like to test them before, but at this point, my apex classic is useless. The display does not work and the nic is dead, so I cannot adjust anything. My ato has been on an outlet that is permanently off and my scheduled outlets are only working 1 hour on and 2 hours off(this is not what it should do).

For the whitebox board, 8 have 2x ph probes on the isolated outlets. The third, non-isolated is a rtd temp probe. I bought it before I new it wasn't supported, so figured I would see if I could integrate it with reef pi. The 2x 1/4 trs are standard ds18b20 temp probes on a pre-configured resistor board.

Edit: Additionally, I mount all my equipment, whenever possible, using threaded inserts and bolts. This prevents me from stripping out the cabinet if I need to remove something and add it back to the same location.

Edit x2: Additionally, using the kasa bars, i can set some conservative timers to put me in a better spot in the event that I have to tinker with the probes.

Got my reef-pi build started this week, really impressed. Started with just getting the Pi going and connected to an HS300. Was working really well for a day, then today it wasn't working anymore and throwing an error that it couldn't get the output pin when I tried to turn equipment on/ off. I set the hs300 to a static IP and verified that it was still in the same IP position and reef-pi was calling that position.

I deleted the hs300 driver and added it again with a new name; however, I'm noticing that it seems to be calling the pins from the deleted driver when I try to load new equipment, and it's still throwing the same error. If I delete all drivers it's still pulling up as having the HS300 0-5 pins still available to add new equipment. Any tips much appreciated.

Thanks!

did it stopped working after you rebooted pi? if so , this is due to reef-pi starting up before network. I just mentioned how to fix it in few posts earlier.

reef-pi does not have a driver for the rtd temperature probe, but it should be possible to integrate it by employing the filedriver (which reads sensor value from a file), and use atalas scientific python library to read the sensor and write it in a file

Cool. I found the atlas ezo global driver library last week before I went out of town. Will have to give this a try. They have a whole suite of modules from ph to temp, salinity, orp, O2, CO2, and others. I personally don't see the need for them given price and my particular setup, but with whitebox boards being stackable, added functionality is almost always a plus.

yes but it still wasn’t working after rebooting pi

did you change the systemd unit file??

 

[InactiveAcct]

Wiring done. Just need to solder the 1/4 trs to the temp probes and mount the box. That will be tomorrow's project. Need to rip out the apex to mount this. I also taped over the hdmis, for the time being since I am not ready to tackle that yet.

wow very impressed at how tidy this looks

 

[InactiveAcct]

I just did. But of course the issue was something much simpler, I didn't update the connectors after updating the driver. Hopefully the systemd update will prevent losing the connection in the future.

If others need to update systems, the more detailed process is post #30 by Ranjib here:

Happy new year everyone. Thank you for making this awesome community

Hello all! I just set-up a reef-pi (v4.0) I got for xmas, and love it so far. I have a temp probe and pH probe, but hope to add some dosing pumps and a PWM dimmer for my BlackBox LEDs in the future. I have one small question which I can't seem to figure out.

The graph ranges for the temp and pH seem to always show zero. The ranges are so large, its hard to get any useful info from the graphs. I waited a day (1 min intervals on both probes), but they still have insane y ranges. I do see other people's graphs and see their ranges are fine... I think in older versions of reef-pi you could set the range value at the bottom of the probe page (under the graph), but I can't see that on my reef-pi...

Is there a way to manually set the ranges on the graphs? Or how long do I have to wait until the ranges will correct themselves (1min*24h = 1440 data points so far, and it still won't correct, and no problem data are in the graphs, they are just flat lines).

Ideally, I would like temp to be 73F -> 83F, and pH to be 7.7 -> 8.5.

This is on the list of things to be changed. Right now it can’t be adjusted.

I know whats happening, this is a common issue when the reef-pi starts before network is up during power up or reboot. You can fix this by updating the systemd unit file for reef-pi to make sure it’s started after network is up

Cause a script to execute after networking has started?

I am relatively new to systemd and am learning its architecture. Right now, I'm trying to figure out how to cause a custom shell script to run. This script needs to run after the networking layer ...

Happy New Year!!! Thank you, Ranjib, I will give this a try.

Out of curiosity, has anyone integrated alkatronic into reef pi? I'm curious if I can just add an extra ph probe connector, if the data sent is the alk number.

none that im aware of

Wondering if anybody can help me out with this. Installed first temp sensor for my build (pi4, reef-pi 4.0). The temp sensor seems like it’s definitely working because it’s showing the temp in the calibrate screen, and it seems to be accurately responding to changes.
However I’m getting errors in the dashboard and in the “edit” menu for the temp sensor.
Thank you

Edit: Thought Id figured it out but I hadn’t

Dashboard error was caused by not selecting sensor. Not sure why I only get one chance to set up the temp probe and then it throws an error every time afterwards

Realized the issue with temp throwing an error at edit is caused by iOS internet browsers. Doesn’t have the issue when using a PC browser to access the reef-pi gui

It should work properly in landscape, the same issue is also on Android.

Oh brother, thanks that worked
