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

[Ranjib]

I'm using putty to get to the CLI in the reef-pi (x.x.3.187) itself, so the commands im inputting are going directly to the reef-pi. The json files are located on the desktop of my PC (x.x.3.229), as well as the download folder in the reef-pi. Any commands from the reef-pi to the reef-pi result in the CLI returning with null. Any commands to the PC result in a connection failure due to timeout over port 80. I'm missing something here, and I can't figure it out. Should I be executing these commands from the desktop of the reef-pi? I did do a full OS load on it, so it does have a desktop. Should the json files be placed somewhere specific in the reef-pi or my PC? If anyone besides @Ranjib knows how to do this, please let me know. @theatrus, how did you go about calibrating your probes for testing? What am I missing?

CLI returning null is ok and as expected . It means it’s working

Last night spend some time fixing couple of bad bugs. Namely the 0 and 100% pwm issue , and ato disable based on threshold . I ll cut a new 3.0 alpha release tonight if things go as expected

I like my new workspace/garage , it’s pretty sophisticated with all the testing gears I need (multi meter , oscilloscope ) and with ample additional builds

It needs more gadgetry! And where is your little helper/director?

I could not add the ph of my picoboard, i get the following error.

even if its selected, you have to choose it again, and the same when you go to set up the probe.

You got this running? I am curious how you think about this feature. Its not very popular use case, I had built it to see my tank images during vacation, when Im out of home. Looking at how complex this for new users, I am thinking if its worth keeping this in 3.0. Users can setup the drive based upload as separate cron job, outside reef-pi,

No, it kept getting the cannot find executable problem.

I think if you can get streaming video working it would be pretty useful but the thing is who is going to have reef-pi in a position to live stream the tank and control everything? Right now I just have pi cam control running alongside reef-pi and it’s working fine. It is web based so it may be easier just to integrate pi cam control into reef-pi. It was easy to install too. You would just need to load http://loacalhost/min.php in reef-pi.

My Pi Zero is inside the light so I can have the camera come out and point downwards but I think most people are not doing it this way and the reef-pi box is probably hiding behind somewhere.

I’m usi

what user you have configured as? reef-pi runs as root,

I’m using user “pi” normally.

You can usually fix this problem with a pull down resistor (for each channel). That would be some high value resistor between your signal pin and ground. That way, if the signal is left floating while reef-pi is booting or otherwise disconnected, the light would see ground as the signal and stay off. Once reef-pi starts sending a signal, it would be much stronger than the pull down resistor.

Let me look into this, thanks for the tip. The PWM pin is connected to a FET and the gate is already pulled to ground with a resistor but I’ll have to measure the status of the gate to see what’s going on.

if exactly that is the solution, but it must be taken as a bug, I think

This is my CPU and memory usage with reef-pi and Pi Cam Control running at the same time. It is recording video 24/7.

yes, its a bad UX /UI bug :-(

Nice workspace, so was the pca9685 100 and zero percent bug fix in the code I identified?

He is busy dis-assembling the layout

The rain boot is on for no particular reason other than his wish :-/

Those 1.65 cpu utilization spikes are not good. I would not recommend running any critical monitoring system in such cpu starved system, if it’s persistent

I like these tanks! Looks nice! Good way to hide the controller too!

That one and more.. there was frequency bug (not sure if that only on 3.0x or 2.x as well) .. here are the relevant changes (some housecleaning changes are in them as well)

Very nice tank. The left tank has an anemone? This light is not too bright for the pico? I worry some corals will bleach.. definitely shrooms

When they are that age, disassembly is ALOT more fun than assembly!

Always working on something just like his papa!

I have a mushroom but it's under the top coral shelf. The light is at 25% on the dinural cycle so it's not at full(25%) for very long.
