Which kind of info about the setup do you need?

Electronics (Raspberry Pi version, ICs), wiring or i2cdetect output, what version of reef-pi you are using (`reef-pi -version` will show).
And the output of `sudo journalctl -u reef-pi.service`

I don't use ds18b20 . I am currently using a coralife digital thermometer's probe (i cut off the probe from the rest and connected a barrel jack to it, if i do it again I'll go with BNC connector instead)

I have two ds18b20, one is for the water to keep trace of the temperature, but the heater is menage from external thermometer. The other ds18b20 trace the temperature of the aquarium lighting

yes, it is enable

Ok. This is a software bug then, I think I know the fix, I just have to patch the software and rebuild it for you to test

Good to know, thanks... How did you connect it to the Pi? Any resistors needed, etc...

Currently, I am experimenting with MCP3008 straight, without any resistor, and see if the values are somewhat proportional to the observed temperature. I have plan to try out ADS1115 as well,

When you say compiled version, do you mean you are building the binary on your computer?

Aaron Smith · Jun 7, 2017

@Ranjib
Do you have a break out of the MCP3008 connection points for pi and the probe? I have PWM and all (8) relays fired up.

Aaron Smith · Jun 7, 2017

I am looking at using a vga cable/connectors, for interface between the (PI/display) and (relay/pwm ). Essentially the outlets, relays, and PWM control will be remote from the PI and display similar to the reef angel. Whatcha think?

I figure I could pirate the parts from an old PC.

You dont need a breakout board for mcp3008, the wiring is straight forward, as mentioned here . Probe one end will be with connected to the analog input, other end to 3.3 v.
It is possible that my current circuit is wrong, for the probe that I am using, some known probes like ds18b20 will solve it, but I wanted to start testing with sensor in general, so my first priority was to get the end to end integration going (i.e. a sample probe + ADC IC + reef-pi code + adafruit.io based dashbaord), which is currently present in reef-pi. I'll iterate over the implementation and fix issues as I move forward.

BTW, Im stoked to hear that you got the relay and pwm working

pic please

Awesome

. Let me know how it goes. I am also thinking doing the reverse, i.e. make reef-pi work on pi zero, and make it a even more tinier. Display will be separate, HDMI or a dedicated Pi instance, whatever. But the actual controller will be cheaper (less than 50$) , and one can add display later if need be. They can use phone or tablet to configure reef-pi via wifi

Sorry, I build with the binary but I noticed that I run the version installed with the .deb

Here is what I'm doing to house the relays and PWM.

This is a pirated UPS with the electronics and battery gutted.

New components installed

Battery access cover allows access to relay module

Cat5e port for PWM to lighting

I may just mount the pi to the outside of the enclosure and ditch the small display for my 32" monitor. My reef is in my home office anyway.[emoji3]

Aaron Smith · Jun 10, 2017

I ended up mounting the pi on the outside of the enclosure. Both channels of PWM are dimming and all relays operate via the "equipments" tab. I have the lights working from the "jobs" tab but the relays won't respond via assigned jobs.

What needs to be entered in the "day" box for a job to run everyday?
Is an input needed for the "seconds" box?

Thanks Ranjib!

Ranjib · Jun 10, 2017

Quoting from reef-pi's documentation:

"day of month" represent which day of every month the job will be triggered. Values can range from 1 to 31

"hour" represent which hour of the day job will be triggered. Values can range from 0 to 23

"minute" represent which minute of the hour job will be triggered. Value can range from 0 to 59

"second" represent which second of the minute job will be triggered. Values can range from 0 to 59

Other than their mentioned ranges, each of this field can also take few special entries.

They are:

"*" represents every . Like every hour, every day etc

"-" to represent ranges. Example: hour can be "2-6" to trigger a job every hour from 2 to 6

"/" to represent after every. Example: Hour value "*/3" represents after every 3 hours

Ranjib · Jun 10, 2017

Let me know if this does not fix your relay jobs. There can be bug, if you find one, I'll fix them . Thanks for testing it out

Aaron Smith · Jun 10, 2017

So the PWM control in the jobs tab works great. I can program on and off dim points for both white and blue channels. The relays don't respond in either "on" or "off" state from the jobs tab.

Another note. If you toggle a relay "off" from the equipment tab, then navigate to another tab, when you return to the equipment tab it shows all relay state as "on"

Have you done a write up on the "Lighting" tab? This is the function that I am most interested in right now. I want to do sunrise to sunset dimming for my Chinese black box. Currently I can control it via the "equipment" tab via sliders. It would be super cool if we could set up lunar cycle via location.
