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

Do you have a picture of your wiring for this? Still trying to figure it out.
its just like in the image above.... Because of the CIRCUIT Board and wires you really cant see how its connected... Its inside this black box...

Ok so I'm getting 3.3v across the whole board, even on the data line. Does that seem right or what should I be getting

Are you getting 3.3V on the GND as well? Did you re-check that the pin on the Pi that you are connected to is a GND pin?
It doesn't matter which 3.3V or GND pin that you use.
Here are a few other pictures that may help.

Random thought I had. Anyone ever open up one of those wifi power strips. I wounder how lucky we could be that the outlets are hooked up to 5v relays, and you could replace the controller with a pi and create something with a simlar form factor to a Apex jr

or just use the pi wifi
 
Just added expand button to ph, ato, temperature probes and lights. With multiple probes/sensors the module specific tabs was getting longer, since each probe/sensor has configuration details, charts etc. Now all the details will be hidden, for individual probes/sensors, unless user click the 'expand' button.

fixed the dashboard loading bug also, where users have to click on ph or temperature tab to get the relevant charts to appear in main dashboard: https://github.com/reef-pi/reef-pi/pull/422

Do you have one wire enabled? What happens when you do:
Code:
ls /sys/bus/w1/devices/

if you dont have the w1 directory, then one wire protocol is not enabled.
 
I have a VERY ODD issue..

Yesterday i decided to plug in all 4 temp sensors at the same time.. I have been using two.. and tested all of the stereo jacks with the two wired probes.. Last night ,well yesterday, When i plugged 4 temp probes into the jacks .. set them up.. they would drop to 32 deg then the sensors would disappear .. So .. i was racking my brain...

I then wired all 4 probes together and plugged them into one of the jacks and they all work fine... Same length of wire, Same configuration in the break out box connected to the main unit with serial db9 cable of 12 ft .... only difference is the 2 ft cable that came on the probes are now connected together then to 1 of the 4 outlets.. To add to this mystery . all of the 4 stereo Jacks pick up all 4 probes in this configuration.. ....

Any Thoughts... My guess issue with the Jacks themselves... they are cheap...
 
or just use the pi wifi
Never thought about this before...
if reef-pi Cound interface to wifi devices (I assume thru serial emulation) on board the RP .. It would open a huge door to available add on devices... Thou i am not convinced its a STABLE thing to try to implement ...

Just a thought
 
How do I wipe the database to start over? I have an equipment that I can't delete.

Found it:
root@seahorse:~# systemctl stop reef-pi.service
root@seahorse:~# mv /var/lib/reef-pi/reef-pi.db ~
root@seahorse:~# systemctl start reef-pi.service

that is strange :-/ . Can be due to powerdraw as well.. ds18b20 has known limitations around length of the chord, i guess by reusing a single jack, you are limiting the overall wire length that the signal has to traverse.

Maybe so... but we are talking about 2 inches of wire for each probe... if its even that much... anyway I know this is not a reef-pi issue and i only really need 3 probes.. Just thought i would see how all for ports work ....
 
The Lighting sliders don't work under Firefox 59.0.2:
The sliders can't be moved. Appears to work fine in Safari 11.1.1.

I would like more granularity on the lights though. I need to feed at 7:30am so need some lights on by then, but don't want them on at 6:00.
