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

1 = 10 kHz
50 = 200 Hz
100 = 100 Hz
1000 = 10 Hz
10000 = 1Hz

The above frequencies I got with the rpi hardware pwm output. I had trouble composing a reply earlier but the frequency setting goes in the wrong direction.

@Ranjib I installed drive and it works with my google account now but I'm still getting the drive is not in path error. Could you show me how to fix that? It's odd because I can run drive from other directories but reef-pi can't it seems. Thank you.

We have had bad storms and tornadoes come through last night, not sure if power glitched but this morning I am getting bombarded with temp sensor emails. I have three probes and I am getting the same message for all three.

Temperature sensor failure. Error:open /sys/bus/w1/devices/28-00000a9aeb40/w1_slave: no such file or directory

Unfortunately I do not always look at my email before leaving and was already at work when I noticed the emails. I guess on the bright side if I am getting emails reef-pi is up but not sure why or how all the temp sensors went sideways. Thinking of having the wife reboot reef-pi but would probably like to see the state it's in before doing that. It's really warm so I don't have to worry about the heaters but have no failsafe since the probes are down.

Any suggestions on looking at post mortem besides logging etc to figure out what happened let me know.

Thanks :)

@Ranjib Does the go path have to be "\home\pi\gopath"? I have it set to "\home\pi\go" but reef-pi can't find drive for some reason even though I can run it anywhere else it seems.

I tried running the command that it says it was having an error:

drive push -quiet -destination reef-pi-images -files /var/lib/reef-pi/images/08-32-19-Thu-May-23-2019.png

no drive context found; run `drive init` or go into one of the directories (sub directories) that you performed `drive init`

I did "drive about" and it shows my gdrive information but it still gives me that error.

Update:
It seems you need the -m option then it will work, like "pi@reef-pi:~/gdrive $ drive push -m /var/lib/reef-pi/images/08-32-19-Thu-May-23-2019.png".

I also tried drive init in /var/lib/reef-pi/images but it says permission denied so I tried sudo drive init but then it says sudo: drive: command not found.

Update 2:
So the root didn't have the path for go. Fixed that by running "sudo ~/go/bin/drive init" in /var/lib/reef-pi/images. Then I had to change the folder permissions by running "sudo chown -R $USER images" in /var/lib/reef-pi.

 

[T-MIKE]

OK, don't perform the second part of update 2 if anyone else is having this problem. You will still most likely need to run "drive init" in /var/lib/reef-pi/images but you do not need to change the permissions.

The way to fix this is when you declare the go path to not set it only for your profile. So just run something like this: "echo 'export GOPATH=$HOME/go'" and echo 'PATH="$HOME/go/bin:$PATH"'.

Well, after all that and a reboot I still get the same error that it can't find the executable.

sudo echo $PATH
/home/pi/go/bin:/home/pi/go/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games:/usr/local/go/bin

Has anyone had ATO disable on alert work? mine will not disable ATO after the 20 sec i have it set at.

Neither does mine. It's inconsistent at best.

 

[trackerit]

you are using pico board? My instruction was for ph board.
I'll update the pico board thread with ph probe specific instruction, we can cross post here :)

Hi, what is the pico board thread?, the ph board is the @Michael Lane??

 

[trackerit]

new build,

I'm waiting the driver for the ph on my pico board, i buy the pihat of michael lane, and i have skipped many welds. its a very work!

Finally made it home, here is the error message from the logs that I am getting from the temp sensors, started happening last night after midnight, haven't searched yet but thought I would post:

May 23 16:53:45 tankpi kernel: w1_master_driver w1_bus_master1: Attaching one wire slave 00.800000000000 crc 8c

This is a new one...for me...:)

Reseated the temp probes and it's working again, I forgot about it rebooting when using the stereo connectors, oops. Not sure what caused the issue, been solid for months now.

The pico board is an all-in-one board by Theatrus.
The other pH board was designed by @Roberto_b. I have sold a few of them.

It's not pretty yet, but my Temp probes and power controller are tested and 100% functional! Thanks again for the awesomeness! Looking forward to the next steps in the project. - Putting it into a pretty case is next on my list.. then we'll see where things go.

The first pic, 2 DB9's run to the temp probes btw. 2 up top, and 2 underneath - Just figured DB9's for everything as a standard connector as they're cheap.

I live in an area with lots of power glitches and my build has been a rock, but i did add the RTC to handle the timekeeping so time is kept accurately until the cable modem boots back up.

Yeah I checked the uptime and the power did not glitch but for whatever reason after midnight it lost w1_bus not sure what happened, resetting a couple of the plugs and it started working again. Not a fan of the stereo plugs and may look at swapping them out for something that has a more solid connection. Actually up to that issue its been solid for almost 5 months, will see how it behaves the next few days.

The light I have if you don’t give it a signal it is at full power. So when the Raspberry Pi is booting the light is on full blast. I’m worried that if the Raspberry Pi ever crashed that the light would be on. Is there a way to circumvent this?

 

[ph123uk]

Hey all,

Can anyone help with how the dinural setting works - how long between each % does it ramp up? e.g. I have set Lights to come on at 10:30am to 21:30pm - With a min of 0 and a max of 80 - How long does it take to get to 80 and what are the increments.

Sorry if its already been published.

 

[ChrisNH]

I just want to sanity check my thinking that I can add the Adafruit guide PH probe circuit to the power/temp/ato circuits on the same pi & hat since it uses sda and scl pins..?

I finally finished and tested the power circuit up through the DB9. I have to do the part I am not looking forward to (cutting the box) then on to the other circuits.

Version 2.2, created an io.adafruit account for telemetry, getting an error in reef pi of "error":"not found - that is an invalid URL

This error only happens for my light channels telemetry data, the systemload and systemmemused works fine - any ideas anyone?

EDIT: Fixed this one, it had SPACES in the light name......

How do i reset my data base ? it been a year and i forgot
