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

Ok. I'll try to do this tomorrow as I hope to have time. I'm good with Excel. Sure wish it was a simple CSV.

I will be glad to help anyway that I can just let me know, in fact I will send you a PM with my email address and you can reach me that way.

Hmmm...

 

[bishoptf]

Hmmm...

Yeah thats not good, you want to look at the first one,

more /var/log/syslog.1

Go page by page until you come to something that looks not correct, something happened that day and some information should be in the log.

 

[pickupman66]

is there a way to advance page by page vs just holding enter and running thru it?

oops sorry, space bar will take you through page by page.

 

[pickupman66]

Thank you. I have a feeling my answer will be at the end of the log here.

You can start from the end also, depends on how you want to go through it:

tail -n 1000 /var/log/syslog | more

That will display the last 1000 lines, you can then page through them that way, lots of options.

Well thats certainly odd, looks like it just locked up, that last line is running cron jobs....

 

[pickupman66]

Tom, I found it. went to just the syslog. it happened at 17:38

@Ranjib amazingly I didnt even notice it until I put my hands into the water. Corals looked good. clam was not open which initially concerned me.

Can you do this and see what your disk space looks like:

Looks like it rebooted for some reason, but it should have started back up fine, ATO looks out of range but I'm not sure why it didn't pick right back up where it left, off. will Look at this more in the morning..

 

[Ranjib]

It looks like the nightly cron job that rotates log etc caused the system to hung up on 3rd. This was not reef-pi related , but Linux /raspbian related (does not matter really ). I’m glad livestock is ok (finger crossed). I’ll dig up and share the watchdog thing soon

@Tom Bishop awesome diagnosis man , love it , very methodical , I would do the exact same step. We are lucky to have you with us. Really appreciate it.

Do you have the watchdog based on reef-pi running or are you clearing it in a systemd timer? It may be useful to fully integrate this into reef-pi. Happy to noodle through this one, since I also want to ship the hard power off watchdog that’s on the Pico board.

I used the hardware watchdog , pretty much this : https://www.switchdoc.com/2014/11/reliable-projects-using-internal-watchdog-timer-raspberry-pi/
Except I use system to enable instead of chkconfig (I think they do the same internally )

 

[KevinDodge]

Has anyone extended the length of the Photoelectric Water Sensor cord? The sensor looks really interesting but its cord is super short. I am hoping to extend it up to 4-6 feet but am unsure on the best parts to do it with. My initial thought are to cut the cord between the sensor and its board and install some sort of 4 pin jack. Thoughts?

On the development side, slowly getting back to ph board support after the flu. The ph driver code in reef-pi now works exactly same as Roberto ‘s example code (value to value match) and integrated from low level driver to reef-pi ui. It still needs some math fixes (values are still shown up as raw analog voltage reading , which needs to be converted to ph) and calibration etc. but I was able to do a hardware based preliminary testing. Without any probe attached it reads 32767 and with the probe attached and the test probe (american marine pin point) in storage solution its 20116. In ph 7.0 buffer it read as -485. All these readings were observed via reef-pi UI, ph chart. I am not sure the values make sense, except its same as the example code of Roberto, and they changed as I change the probe. This is good enough for me to proceed to next level testing where that I need for conversion and calibration work and I am not very confident on the probe
anyway. So here is a build in progress, it will house a Pi 2 (i have lots of older pi, and I thought why not, I should test these older model anyway, since reef-pi should work just fine, and I know at least a dozen of builds that are running these, so I might have one build each with pi 2 and model B). Anyway, here is the initial version, this build will house two temperature probe and ph probe. ph probe is backed by ph board. I am yet to finish the wiring/circuit. Only enclosure fabrication is done. But once completed (tomorrow likely) I'll be able to test the ph board as well as the american marine probe against my atlas scientific ezo circuit/probe based build.

Objections if I contribute a driver to do the reset in the reef-pi software? I’ll add support for the SMC while I’m at it

Excellent. I’ll test drive the integrated driver on the Pico then. While the scaling is different the output is also voltage.
