Is this for wavemaker control?

That's what I'm working on with the Jebaos.

I haven't pulled the trigger on a wavemaker yet, so if this works, it will greatly influence what i buy.

If it does work it should work with any of jebaos even their gyre models. I'm a bit of a ways from testing though.
I'm still working on the temp probe and dosing pumps.

I've spent most of the day today trying to figure out how my second rpi just randomly changed resolution modes. Now that I got that fixed I can get back into the dosing pumps and getting those up and running.

Hello Guys,

Having some issues getting the temperature sensor reading with my Pi Zero W. I had "something" working last night. I was reading three different "temperature" sensors with only one sensor plugged in, and none of them seemed accurate (off by over 12 degrees (f)). It also wasn't working out of the box, but I did something (don't remember what) and was finally able to see it.

So I reformatted the sdcard to try again and still not getting anything read. I have i2c & w1 gpio enabled through the raspi-config. Running the latest 2.0 rc3

My boot.txt looks like:

Code:

pi@reefpi:~ $ cat /boot/config.txt # For more options and information see # http://rpf.io/configtxt # Some settings may impact device functionality. See link above for details # uncomment if you get no picture on HDMI for a default "safe" mode #hdmi_safe=1 # uncomment this if your display has a black border of unused pixels visible # and your display can output without overscan #disable_overscan=1 # uncomment the following to adjust overscan. Use positive numbers if console # goes off screen, and negative if there is too much border #overscan_left=16 #overscan_right=16 #overscan_top=16 #overscan_bottom=16 # uncomment to force a console size. By default it will be display's size minus # overscan. #framebuffer_width=1280 #framebuffer_height=720 # uncomment if hdmi display is not detected and composite is being output #hdmi_force_hotplug=1 # uncomment to force a specific HDMI mode (this will force VGA) #hdmi_group=1 #hdmi_mode=1 # uncomment to force a HDMI mode rather than DVI. This can make audio work in # DMT (computer monitor) modes #hdmi_drive=2 # uncomment to increase signal to HDMI, if you have interference, blanking, or # no display #config_hdmi_boost=4 # uncomment for composite PAL #sdtv_mode=2 #uncomment to overclock the arm. 700 MHz is the default. #arm_freq=800 # Uncomment some or all of these to enable the optional hardware interfaces dtparam=i2c_arm=on #dtparam=i2s=on dtparam=spi=off # Uncomment this to enable the lirc-rpi module #dtoverlay=lirc-rpi # Additional overlays and parameters are documented /boot/overlays/README # Enable audio (loads snd_bcm2835) dtparam=audio=on #ReefPi Settings dtparam=i2c_arm=on dtoverlay=w1-gpio dtoverlay=pwm-2chan

(I tried specifying the gpio pin also, but it didn't make a difference).

lsmod:

Code:

pi@reefpi:~ $ sudo lsmod Module Size Used by bnep 11981 2 hci_uart 27218 1 btbcm 8248 1 hci_uart serdev 9370 1 hci_uart bluetooth 366986 24 hci_uart,bnep,btbcm ecdh_generic 17649 1 bluetooth brcmfmac 273230 0 brcmutil 9114 1 brcmfmac snd_bcm2835 23253 0 snd_pcm 89686 1 snd_bcm2835 snd_timer 22428 1 snd_pcm cfg80211 542402 1 brcmfmac snd 60154 3 snd_timer,snd_bcm2835,snd_pcm rfkill 21476 6 bluetooth,cfg80211 i2c_bcm2835 6465 1 pwm_bcm2835 3254 0 w1_gpio 4566 0 wire 31600 1 w1_gpio cn 5687 1 wire hwmon 10505 1 wire uio_pdrv_genirq 3718 0 uio 9901 1 uio_pdrv_genirq fixed 3033 0 i2c_dev 6674 2 ip_tables 12427 0 x_tables 22130 1 ip_tables ipv6 397455 24

Was expecting to see something like:
wire 31600 2 w1_gpio,w1_therm

But that won't show without doing a sudo modprobe w1-therm

Based on the /sys/bus/w1/devices it doesn't appear to be seeing the sensor.

Pic of the breadboard attached.

Any thoughts or something stupid I am overlooking?

Edit: Oh yeah, I get this error:

Nov 18 13:11:45
Failed to initialize i2c. Error:eek:pen /dev/i2c-1: no such file or directory

When I was able to get rid of that error ( messing with the i2c settings in the config based with what I found online) that's when the "three" temp sensors appeared...

Don’t reformat sd card or reinstall reef-pi if something is not working. They are rarely the culprit. Using raspy-config to turn on i2c and one wire. Which guide you are using ? I recommend using the new guides published in adafruit (particularly guide 1 and 3) .
Your wiring looks correct . Did you reboot after configuring everything ? Touch the probe after you hooked it up. And also measure the voltage on the three pins of your probe

Ranjib · Nov 18, 2018

Dosing controller guide in adafruit is complete, it’s waiting for editorial reviews and probably will be published on Monday or Tuesday.
With this , all the critical documentation is done (7 guides ) . I feel relaxed and can focus on field testing. I think we have most of the things (software bugs, hardware/circuit details) chalked out. Unless there concern I think we are good to go and make 2.0 public release and announcement

Cleaned up my closet a bit and removed 3 empty DA pc4. Then screwed the reef-Pi outlet bar to the board. I plan a 2nd one just below tthe existing for my 16 outlets So i can remove the white power strip

Duh, my stupidity got me. This is exactly why you should always measure voltages.

Each of the little +/- banks are isolated from the others. I didn't realize that (my last breadboard didn't have those separations so I wasn't really thinking about it). So there was no voltage to the probe.

Anyways, got it hooked up and now it's reading the sensor and working right!

I am still getting that i2c error though. Any thoughts on that?

enable i2c using raspi-config, and reload reef-pi or reboot the whole pi

Designing the actual circuit to add it to the rpi is beyond my knowledge but maybe there is a way to hijack their board and have reef-pi control it?
This would also be cool if we could figure out a way to use the Jebao wireless OW series pumps and have the rpi control the with wireless but that might be a bit of a stretch since their wireless capability is just to link the pumps not to control them remotely from a main controller.

I have a Jebao SW2 and I've looked into both controlling it wirelessly via slave mode and controlling it via the input in the controller. I assume the other models are similar. If you search for Jebao in the previous conversations (...somewhere in this thread) you'll find it.

I haven't dug into wirelessly because their system uses a nrf24l01 transceiver and you can't sniff the signals from it. It's possible to wire into the transceiver and record the different signals for emulation but not something I want to dive into.

According to the previous convo, it's possible to build the circuit according to the Kessil light diagram but without the transistors (to bring 10v down to 5v) and use it in the same way - audio cable to Jebao input. Not sure what the other controllers look like but my Jebao input needed to be rewired to use an audio input but that was fairly simple. It worked for on/off control but I didn't test it further (speed, etc). The issue is on the programming side. It's possible to script different waveforms and patterns but it's a big job and not something I'm familiar with.

This means the dtparam line is missing from /boot/config.txt

dtparam=i2c_arm=on

Just tried within raspi-config and rebooted. Still getting error.

That line is in boot/config.txt already.

ok, i2c-1 is present. Then reef-pi should not complain about it being absent. Lets check how you running reef-pi., What is the out put of this, this will restart reef-pi and we'll see what happens once it comes up.

Code:

sudo systemctl restart reef-pi.service
journalctl -fu reef-pi.service

Question, how you installed and started reef-pi? and what version you are using?

Can I ask, I have mars aqua leds 165w x4 all stripped down so modding them I'm not worried about, but if I want to pwm them properly how could I do it? The panels themselves contain 55 3w leds, I have 4 panels, so a total led count of 220 3w leds.

Now there split into 2 channels per panel, white and blue channel, blue channel uses 27 leds 3w each, white channel 28 leds 3w each, it uses 8 drivers that have manual dimming.

Now I'm thinking to replace how there powered by a better system than supplied so they can then be fully controlled by reef-pi via pwm and timers from the pi.

I've been researching some but it's very confusing on the power side of things, has anyone done anything like this? Or any advice about powering a strip of 108 blue 3w leds and pwm and a strip of 112 mixed white channel leds 3w.

Is it even possible to power and pwm so many leds in series?

Is the manual dimmer something like this?

This is the circuit that has been working for my SBReefLights with Reef-Pi control.

It is plug and play into the system and uses the 12V from the light system, so all you need to send is signal and GND.

I have been looking into this as well. Mars Aqua use 0-10v analog dimming . The dimmer is different than that ( on mine at least) They have VDM connection but this wiring should work.
