Haven't been keeping up, so I haven't read all the pages for this thread. Not sure if you've seen this before or not but in case you haven't I posted here.

Adding this in case you want to pursue:

He's dosing to his tank. Nice.

So now that the main 3 modules are done, I started setting up reef-pi to my likings.

With the lighting profile. I thought there was one hour increments instead of 2 hours? Has it always been 2 hour increments? Is there way to change that? Not complaining just wondering.

It has always been 2 hrs interval. I intend to make it customizable in 3.0

Ok I must have been thinking about something else. Not a big deal though. You sir and the others who have programmed reef-pi have done an amazing job! Thank you for all your hard work!

@Ranjib I'm still working on diagnosing the high CPU and RAM on the latest install.

The big drop in the middle of the historic was from a restart. Then it looks like it was happy for a few days. I cant think of anything right now that caused it to start increasing a few days ago.
Looking at the journal, I think it was still unhappy setting 0 for all of the configured GPIO pins (all 16 from the PCA9685).
Would it be possible to have a disable button on the lighting tab, as there is for the timers, temp, etc...?

I removed most of the PWM pins and went to reload and I get this message in the journal.
I am holding off rebooting to see if you wanted me to test anything.

thats does not look good. Whats the output of

CPU spikes are better and RAM usage has stopped growing, since I deleted all of the other PCA9685 pins

CPU spikes are better and RAM usage has stopped growing, since I deleted all of the other PCA9685 pins

I suspect leaking Go routines here. Need to look at the code some.

The one in the above image is the very first version of the controller. Its using a wooden handmade housing (Im really bad at wood works), it powers one of my pico (fluval spec III). Here are some details:
- Main controller board: raspberry pi 2
- 8 channel sain smart relay, two of them are connected to two perstaltic pumps (mounted at right side of the housing), they are used of dosing/ATO
- There are 6 110V AC outlet mounted at the bottom. Return, powerhead (coralia pico evolution), stock LED, heater all are connected to the AC sockets.
- In the front, it has a 7" LCD screen (from Adafruit), can be switch on/off using the controller UI.

Below is the image of internals of the housing, Note: I have gutted a 6 port extension to repurpose its surge protection electronics. It also had two 5V 1 A USB outlets, which i use to power the raspberry Pi as well as the display. The ancillary breadboard on front panel hosts a MCP3008 and an L293D IC for sensor and high voltage PWM controls

do

Do you see any reason I can't just use my rpie2 and the 8 channel referenced to run my pumps, heater, and lighting?

And have 5 more relays for future use

CPU spikes are better and RAM usage has stopped growing, since I deleted all of the other PCA9685 pins

This is with pi 3 or pi zero ? I am assuming you are running headless. I'll try to reproduce this, soon i get some time to work on the code side. It will be very helpful to know your reef-pi setup, if you have a build thread, i'll dig it up, else just share some summary information here. It looks like a memory leak , but I am not sure.

Do you see any reason I can't just use my rpie2 and the 8 channel referenced to run my pumps, heater, and lighting?

Yeah, this should be fine.

Haven't been keeping up, so I haven't read all the pages for this thread. Not sure if you've seen this before or not but in case you haven't I posted here.

Peristaltic Pump DIY

Adding this in case you want to pursue:

He's dosing to his tank. Nice.

Thank you for sharing

, I'll take a look

Pi zero running headless, using an Adafruit Motor Hat and running the custom version 2.0-2-gae06032 to allow addressable PCA9685.
I dont have a build thread, though I probably should have started one along the way.
Thanks for the help, let me know if you need any specs or any testing on my end.

Had to flatten the bottom and take some space in the corners to make both boards fit and flush with the sides.

Been very busy with apartment move. Its almost over now

. Its amazing how many things we had. Having a kid adds a lot of extra things.
I am thinking of cutting a minor release (2.1) with the doser calibration fix and configurable pca9685. Theres a big hal refactor going on which is important to streamline the support for all new drivers (ph/orp board, baseboard, daughter board etc)

These corners give me headaches as well. This is one of the reason why I think 3d printed enclosures will be very useful. But they are very well built, and I love the clear top, it lets me see all the inidicator LEDs

Any idea what would cause an occasional spike in CPU load like this? It looks like it goes up (sometimes very high) over about 10 min and then down again shortly after. This is in the course of an otherwise normal day. This was actually a day when I was out of town so it was really on autopilot without me there to poke at it.

Also, is it a problem? I'm happy to ignore it if it's a random occurrence.
