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

[Ranjib]

I'm getting errors when reef-pi tries to connect to adafruit IO, it's trying to connect with IPv6, but I have that disabled. What can I do about that?

It’s a Linux thing. Disable ipv6 advertisements on router

Has anyone hacked into an eheim auto feeder yet? I’m debating cracking mine open to try and make a reefpi auto feeder.

Hello everybody,
the ReefPi project is great!
I would like to use the ADS1115 16 bit ADC i2c interface on Reef Pi, i'm a newby in raspberry world but sometimes i worked with Arduino.
Should i create drivers to use this ADC for temperature or PH monitoring? I have analog sensors at home like pt1000 and i wish i could use them.

Here's some images I made up a while ago showing how to do it. You can use any logic level mosfet, the green line in 1st image goes to any I/O pin on the Pi. The blue line is what solders to the Eheim PCB.

To run in Reef-pi add an 'outlet' connector for that pin and setup the feeder as a piece of 'equipment'. Then setup a timer and set it to turn off after 1 second. This will be the same as you pressing the manual feed button for one second.

Base = Gate
Collector = Drain
Emitter = Source

Try nano . It’s a text editor .

I get this hierogliphs..

:-O , you have opened a binary file ( program)

Nice.

This is what I hoped to accomplish with my Juwel feeder, but with that you can't turn off the feeding schedule, so my only work-around was to turn the unit on and off.

I can't find the post, but there was someone (from Europe I think) that posted about setting up a reef-pi for his setup (I think it was a freshwater setup) and he got an autofeeder to work as well. I think it was an Eheim and and he got reef-pi to activate the manual button.

IPv6 is disabled on the pi and have never been turned on my router as my provider does not support it.

So how can I open right file?
I dont have a clue.. I just followed your walkthrough Ranjib.

this is perfect! I already have the transistor in place powering some relays I don’t use any more so all I need to do is run the wires.

Ranjib I have found it under home/pi not under var/lib/reef-pi..
This are commands I used for my and others future reference:

sudo systemctl stop reef-pi.service
sudo reef-pi db list ato
reef-pi db -output reef-pi.db show ato_usage 1 | jq . > usage.json

Then modify file under home/pi

cat usage.json | sudo reef-pi db update ato_usage 1
sudo systemctl start reef-pi.service

This is normal if you have alot of things set up in reef pi. You get 10 free feeds with a free adafruit io account and so many feeds per minute. If you go over this amount adafruit ignores the feeds and may not accept them.
As of this time there is no way to decide which feeds get sent as reef pi sets them up automatically. one thing you can do is not set up monitoring with small intervals which would cause you to exceed the number of feeds per minute.

Hello everyone. I have a question with the hs300. If power goes out it will not reconnect with reef-pi. I can still use my phone to operate it just fine. I locked the IP address on the hs300 but every time I power the PI off then back on it gives me a connector error in reef-pi when I try and turn the equipment on. I have to delete the whole thing working backwards if I dont first delete the equipment then the connectors then the driver it locks me out of the connectors screen and I get this error. Has anyone else had this issue and knows of a fix? Thanks for the help

Question... Was working on getting my ph sensor working after combining my dosing reef-pi build with my first reef-pi build. I got it to work, calibrated it and connected my dosing setup and pca9685 when I wasn't able to set my dosing working. I found a missing connection in my soldering ( can't remember which one) , resoldered it and got the dosing setup working. Now my pH probe isn't found by i2cdetect.

I checked wiring and completely redid it twice... (5V to 5V, SDA to SDA, SCL to SCL and Gnd to Gnd) using the isolator board. It seems I have continuity between all connections (0 ohms) and when plugged in the standby blue led it always on, voltages across ground and 5V check out and my SDA and SCL were around 3.6V. Still can't see it on reef-pi or through console on i2cdetect... Any ides on what I should try?

What address is the pca board? And what address is the ph isolator board? If they are the same you may not see one on the bus.
Also try one thing at a time...disconnect the pca and try the ph board alone...does it show up? Do the same with the pca9685. Are you feeding the i2c thru the pca9685? Maybe something on the feed thru is messed up.

Disconnecting the PCA and dosing setup I do not see any address from the ph board.

If its not showing in i2c detect that sounds like an external wiring issue or the ph board is not working correctly. Check over everything carefully...make sure an errant blob of solder didnt go somewhere it shouldnt have or something similar

 

[NeonRabbit221B]

So decided to check if my dosing system was still able to be detected on i2c and kabam the pH board can be detected now. Still can't get it showing up on reef-pi. I2c shows it at the address 0x70 which is 112 in decimal. Changed the address and rebooted but still nothing.
