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

[Erica-Renee]

I did this and ended up with the same result.

Are you using Resistors in your Circuit..
Here is the example i used to wire mine. I think your missing the resisters unless they are on the back side of your hat .

In your dashboard configuration under ato you have nothing selected. this will cause this error.. removing the ato from the dashboard totally and check the ato sensor in the ato tab.
It will take a few min for it to start working..

Hello everyone.. I wanted to start with saying amazing job on Reef-Pi. I dont have mine up and running the tank yet but it should be soon. I also have a few questions I'm going to have 3 temp probes do I just select any pin I'm not using for my other two probes or are there certain pins I need to use? Also hows the PH probe going? I have not seen anything on how to hook it up. Sorry when it comes to the programming side of things I'm not very savvy. So understanding how the tech end of things work I'm lost, and trying to learn as much as I can. Thank you.
Attached a pic of my Reef-pi in progress.

beautiful, thank you for giving reef-pi a shot :-0) . Welcome to reef2reef. Temperature sensors all share a common wire, GPIO 4. Irrespective of how many you use, it's called one wire bus.

I am in process of finishing up the pH monitor build. It will be published next week hopefully, Its been for few months now, but I never got to document the build guide.

My Next project . will be one day when its to cold to work

No resistors on the pi hat the optical sensor has a 3 pin connection that goes to a break out board with 4 wires going to the sensor.

My 125g tank was setup with RKE controller and several modules. I have been trying to source a new head unit but I was not successful since the company went out of business.

Would it be possible to be a reef-pi controller that would reuse some of the RKE module such PB4 power bar, ALC light control...?

Thank you

 

[Ranjib]

Here's the circuit.
The error message comes up every time the sensor tries to take a reading I have it set for every 10 seconds.

ATO page.

Your circuit and configuration looks correct for photo electric sensor. Are you using float switch ?

Thank you for the help on the temps and also on the ph I'll be keeping an eye out for it. I haven't ordered the PH probe yet but I want all my jack for everything installed before I mount the box. Thanks again.. and amazing job.

No go on the old rke equipment. I'd love to as I have 4x of the pc4 and all the other goodies.

 

[Diamond1]

No just the optical sensor.

your circuit looks fine to me. If you probe the three pin (5v, GND and GPIO 17) on the male header jumper, do you get expected reading, particularly when you put the sensor in and out of water?

 

[Diamond1]

Like I said in an earlier post I constructed the circuit on a bread board and hooked that up to the pi without the hat on and got the same result.

 

[Diamond1]

I'll give that a try and see what I get for readings.

ugh. that s a bummer. Feels like a lot of wasted money now.

Ok I just rebooted the pi put the sensor in the water and it shut the relay for the pump off pulled it out and the pump turned on, but I still have nothing for the ato on the dashboard. I refresh the page and get the error message
and the column where the ATO is supposed to be is blank.

In your screen shot above the Dashboard Configuration under ato on the right you do not have a ATO Selected ..

and for some reason i was thinking the sensor and switch were the same My Mistake..

DERRP! I was so worried about the sensor not working right I didn't notice that.
It's ALIVE!
Thanks Erica

@Erica-Renee is simply awesome :0)

 

[Diamond1]

No to get the temp probe going and I'll be golden. Till I decide to add more stuff.

Yes she is! She has saved my butt in this build now a couple times.
