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

All I use is tap water, prime as a dechlorinator, and sometimes some ferts.

Same here...dechlor only, no ferts though, thats what the overstocked tanks job is.

@DirtDiggler2823
Have your plants ever pearled? Growing under strong light so fast thay they are giving off o2 in bubbles?
Mine pearl a bit daily after the first hour of being under my leds at full intensity. I think that means they are using co2 at a pretty good clip!

I'll only see it if the return pump is off for a while, but I've seen it.

I’m excited to report that the ph board driver is now running for almost a day, I believe what I’m seeing is a daily ph cycle, but represented in raw milli volts

Nice. Will we see a Reef-Pi alkalinity monitor soon.:D

I sure hope so :D

Hi, First thanks for all the hard work. I'm just about done with my initial build and it all went well. I'm still waiting on the ato sensor. I've got the power strip up and working, email notifications, and three temp probes. I'm a bit concerned about the probes rusting and am thinking that covering them with a thin layer of aquarium safe silicone over the stainless bit and just up past the shrink seal would be smart but thought I'd check in here first. Thanks again cool project.

You should make a build thread

A few people have done this, myself included. It works well for me, except I found it very difficult to actually coat the probe with silicone. I used styrene tube filled with silicone and inserted the probe into the tube. It was a lot less messy that way, and works well for me.

Welcome to reef2reef . I am using the powder coated canakit probes mostly, I have only couple of bare steel probes, none of the has shown any rusting yet

just a quickie if anyone can help,
I've attached a screen shot of my reef pi dashboard and the temp scale goes from 0 degrees to 90 degrees.
I'm hoping i can set that myself to something a little more granular like 65 to 90 for example ?

cheers

You can set the minimum and maximum on the Temperature page for each probe. The range will snap into place once you have enough historical data.

I'm trying to set up temperature monitoring, but the temperature sensor is not showing up. I have the temperature box checked in the configuration & have updated & rebooted. When I try to add the sensor under the temperature tab, there is nothing in the sensor dropdown. I checked in the connectors configuration & tried to add it as a jack on pin 4 (physically, pin 7, GPIO 4) , with rpi as the driver but it tells me the pin is invalid. 1-wire is enabled as well, already ruled that out.

Any ideas on what could be going on?

If it's not under the temperature as per https://learn.adafruit.com/reef-pi-guide-3-temperature-controller/configuration-testing and it has need enabled it may be wired wrong can you post a pic?

Can you share the circuit image, did you enable one wire ? Can you share your temp probe Ui?

 

[Schreiber]

You're not really going to be able to tell much from an actual picture, too many wires in too close proximity. Here's my fritzing diagram:

There are a few extra things captured here, but the jack on the left is the audio jack with all its connections.

 

[Schreiber]

This is what it looks like when I go to add the probe:

I went through the steps to enable 1-wire through the raspi-configuration. However, I have an error saying I2C wasn't enabled.

 

[Schreiber]

I noticed @AquaRaider44 posted about the exact error I'm getting about I2C last night. Could this be the issue?

My temp sensor worked fine as soon as I installed it but I had i2c setup beforehand so maybe u should check and see if that and one wire is on then reboot and try again.

 

[Bigtrout]

Do you have onewire enabled? If so, can u SSH into your pi and run this command.

ls /sys/bus/w1/devices/

Do that and see if it lists any sensors.

If not there is a wiring problem somewhere

 

[Schreiber]

Hmm, so I guess that's not it. I'm also getting this error upon boot:
{"error":"Item 'usage' does not exist in bucket 'temperature'"} | HTTP 404

I'm 100% sure I've enabled one wire & I'm still getting the i2c error as well.
