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

[Ranjib]

Life has been busy , since I got my 3d printer

It’s been running almost 12hrs a day since then .


Idea is to learn how to model and print things over the course of next few months . Some calibration prints first

Not perfect , still a lot needs to be improved , but good enough to get started , I guess
First print was a pi case for octoprint, the opensource software that allows remote management of the printers and runs on pi

Next, Ryan wanted his car to be printed, before he allows me to work on it at peace. He is becoming an IRS like entity at home

Next is modeling a reef-pi enclosure and print it

I am having trouble calibrating my ph sensor. Specifically I can't create a cookie.txt file.
This command "
curl -X POST -d '{"user":"pi", "password":"mike"}' -c cookie.txt http://192.168.1.161/auth/signin
"
runs and says "null"

Then I type ls -alh and I don't see a cookie.txt file.

This worked on the first pi, but this type nada. Any suggestions?

Everything looks good except the output of ls. Can you share a screenshot of your terminal ? Something is missing, probably the file is being created in different place . Cause sign in is happening

well I fixed it. YAY

I re-entered my login info into reef-pi authentication tab. Rebooted and tried again. This time the cookie.txt file was created. I must have not been giving the right login and password to reef-pi as I didn't update them after installing reef-pi 3.0

Im glad it worked out. But I do think reef-pi has a bug , or unexpected behavior. Ideally it should respond with some kinda error message indicating a failed auth. Put otherway there should not be silent yet bad failures. I'll see if i can get time and fix it. It will be nice if you file a bug report. I wont forget that way

Sweet! I am sure you'll be a pro and be printing top quality items in no time. I believe you already know this but there is a 3D printing thread on R2R and many of the members are extremely helpful with new users.

I have seen this, with the real gigbit ethernet this may be a good reef pi upgrade for me

Ahh you beat me to it...

I think the pi4 is way overkill and at some point defeats the purpose of a pi in the first place. 55$ for the top model is getting kinda expensive as well expecially when I have like 4 of them.

Yeah. I was hoping for more gpio or other peripherals. There are talks of additional i2c port. It would have been nice if they had added sata or Emmc storage .

I completely agree and hope you won't ditch pi 3 support as I definitely won't be upgrading.

 

[DirtDiggler2823]

I'm curious to see how much better it could perform with the base board. I might also be able to integrate a camera with the extra power and RAM.

Not at all. There will be pi 4 binaries going forward, along side pi zero/model B and pi 2/3 binaries. These are basically arm6, 7 and 8 respectively. Expect reef-pi to drop support only when offical Pi support ends . likely in 5 to 10 years, but even then it only mean new things are not available, old binary/packages should always/ever work the target platforms. Its not a python or ruby type package that one has to build on the pi or depends on various other things, reef-pi is a self container binary, hence once compiled its available for ever, without much dependency on the platform.

Yeah. Thats what I am thinking as well. The GPU is much better and theres more memory, this gives us lot of opportunity to do some image processing, machine learning etc.

There is AI support via the USB 3.0 appearances, as well.

last night while i was at work (Late shift uughhh) my reef-pi started spamming me with over temp alerts from my tank.
which is great that's exactly what i wanted it to do, I think it was my heater which I've cleaned all the encrusted gunk of it, tested the operation of it in a bowl of water and refitted it. although now i'm looking warily at my return pump but we'll see.

anyway to my point ..... reef-pi was sending me email's every minute. can i change the frequency of the email's to send me one every 5 minutes say?

Cheers Guy's

Yes you can, the limiter is under the telemetry section, how many emails per hour.

You could also change how often reef pi polls the sensor. That is located within the sensor setup. Default is 60sec. Keep in mind this is also effect how long your heater stays on if you have a heater controlled by the sensor you change.

What i would is have one sensor that reports back to you set to 5 or 10 min update intervals and then have a default sensor that has no alerts set to it that only controls your heater af the default 60 sec update rate
