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

Can you upgrade to rc-2? There were bugs where if you have pca9685 enabled but not present in circuit, reef-pi will crash fatally

pi@Tank:~ $ reef-pi -version
2.0.0-beta

"Crash fatally".... sounds a little daunting! Lol

yeah, if reef-pi is not running, we call it fatal. Generally we try to make reef-pi work, even if things are not in good state, at least be running and show errors.

I'm having an issue with setting up my optical sensor. I set it up on the inlet tab, I'm able to set the sensor up in the ATO section, assign it to an outlet and save the setting for it. Then regardless of the sensor being in or out of water it turns the outlet on and wont shut off even after the sensor is re submerged in water.

I ran: cat /sys/class/gpio/gpio17/value and it says 0 even when the equipment tab shows the #2 outlet to be on. I also get an error message {"error":"stats for id: '2' not found"} | HTTP 404

I thought maybe it was a problem with the circuit so I pulled everything apart and set the same circuit up on a bread board and got the same results.
I'm running reef pi version 2.0.0-rc2 on a pi-3

Also the ATO is not showing up on the dashboard

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.

Hey @Diamond1 - why didn't you post this on your own build thread? Is it because it might be a common problem?

you can check the circuit without the sensor by connecting the pins together. this could rule out a problem with your wiring .

@Dave's Reef - nice looking set up! Are those all 3.5mm Jack's you used?

I believe you'll be fine hooking the extra temp probes to any pins as long as you assign those specific pins to them and set them up as such.

 

[That Crusso Kid]

@Dave's Reef - "Jack's" should be jacks. I think I'm going to have to turn off auto-correct on my phone. It appears to be incorrect more than it's correct! Sorry 'bout that!

The temp prob uses the one 1wire protocol You can have latterly 100s of 1wire devices on the same pin. so it connects just like the existing one .. Just be sure you connect and disconnect the probes while the Pi is turned off. as they will touch and cause pi to reboot . or cause a short... i think cat3 or 5 plugs would be much better then the jacks

Thanks and yes they are I currently have 6 of them 3 for Lights 3 for Temps (DT, Sump, Mixing Station/Air). I will be adding at least 4 more, 3 levels and a Ph (my plan is to buy the Atlas Scientific pH Kit 0-14 pH kit) and make a small box to house the chip and plug for the probe next to my sump (in the basement) and run a 3.5mm extension cable from the remote box at the sump top the main Reef-Pi box under my tank.

Thanks for the help I will hook them up that way. as for the cat3 or 5 plugs Im an honestly not worried about unplugging the temps while things are running I like the ease of the 3.5mm jacks and extension cables. but thank you for the pointers

I think I stand a better chance of the experts seeing this and helping out. If it is a bug maybe it can help @Ranjib can use it to better the 2.0 release.

Are you talking about the data pin and hot pin on the sensor board or on the pi board?

That stats not found error is expected soon after you create an ato, it should go away within a minute, when the first check is done.
Can you post a photo of your circuit? and a screenshot of your ato page

 

[Ranjib]

Also the ATO is not showing up on the dashboard

Can you share a screenshot of you dashboard configuration ?

 

[Erica-Renee]

Are you talking about the data pin and hot pin on the sensor board or on the pi board?

There are two wires one is a Ground the other is the hot/data pin.. a standard mechanical float switch (not a sensor like you have) Does it open or close the Circuit .. Does this make more sense.. Its just a standard on and off switch..

 

[Diamond1]

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.

I did this and ended up with the same result.
