I was only having issues with that one .. the color was working fine. but I did reverse it and it seems to be working now.That sounds strange. Might be useful info for @Ranjib
Did you try that „reverse“ checkbox on the Jack(s) as well ?

Not personally, no.@Sral , Are you using a telemetry server? I believe this will be my next step. I am assuming this is just for graphing and saving data from reefPi and not controlling? I just set up my tank and would like to have a small screen beside the tank showing the data. But I am unsure if I do this will it auto launch? Like if I have a power outage and when it comes back on will it auto launch to the graphs, or will I have to launch the graphs myself? What I am reading from the guide the server will launch automatically but I am unsure about the UI.
No, the PCA9685 can't read temperature probes, it only sends out PWM signals.Adding more Temp probes is just adding each set of wires to the correct pin on the PCA9685 Correct?
Not personally, no.
As far as I understand a Telemetry server based on Prometheus and Grafana is just for visualization, right @Ranjib ?
There were however other people using somethign like a Home-Assistant setup that could do both graphing and control, If I recall correctly.
A telemetry server is a lot more CPU and memory intensive. As far as I have heard it wont run on a Pi Zero. Ranjib has recommended a regular x86 miniPC system at least (He is running his with Linux I think). You might get away with running one dedicated PI 4 or higher, but I don't know how well that would work, if at all.
How were you plammimg on running a display ? Meaning, what computer architecture and what interface, e.g. ReefPi on WebBrowser, Custom display or Grafana ?
The only such thing I have seen was "Kivy Reef", but that would run from a PI 3 or 4 that runs ReefPi in parallel as well, if I recall correctly. That, or or Home Assistant systei
That means what exactly ? Do you have a link to a specific product or thread ?I was thinking about one of them Portable monitors.
I was going to get a mini PC x86 base and get a portable monitor like theseThat means what exactly ? Do you have a link to a specific product or thread ?
As mentionend before, you can add them to the same pin, as I have done here:@Sral or really anyone... I was looking around online about how to add a second probe. I think I found a way.. but I want to ask to make sure...
I was thinking about adding the probe to "GPIO16" and adding this line to the config file
"dtoverlay=w1-gpio,gpiopin=16"
... If I am correct, could I add the "gpionpin=16" to the original line or will I have to add a second line?
dtoverlay=w1-gpio,gpiopin=4
dtoverlay=w1-gpio,gpiopin=16
As mentionend before, you can add them to the same pin, as I have done here:
Although, if you have the pins to spare, just use a second pin. THanks for the code, thatw ay I was able to find @robsworld78 's post I mentioned earlier, here
So you can just add a second line with the other pin:
that would enable OneWire on pins 4 and 16Code:dtoverlay=w1-gpio,gpiopin=4 dtoverlay=w1-gpio,gpiopin=16
That works, yes. Just watch out that you solder it right, otherwise a bad contact in the chain will compromise the network/bus.sorry I need too edit I can Daisy chain the PCA9685 and the PH mod to the PI
Something like this.. I'm assuming I can do this as the pins are the same on both sides..
... I want to use one PI so I will only have to remember 1 IP address.. unless there is a way to connect 2 pis to the same IP address. not asking that correctly, hope it makes sense..
sweet! ill look at starting the PH Mod soon .. just need to figure out about the dosing pump..That works, yes. Just watch out that you solder it right, otherwise a bad contact in the chain will compromise the network/bus.
Oh, right, forgot about that, sry.sweet! ill look at starting the PH Mod soon .. just need to figure out about the dosing pump..
Right, sry. It is basically 16 pins that do the same as pins 18 and 19 on the PI that are used in the dosing module. They put out a rectangular voltage wave that oscillates between 0V and nominal output voltage. Depending on the setting it will stay between 0% to 100% of the time of one period on the output voltage. That’s called PWM or a PWM signal.I really need to research more into PCA9685.. Im not quite understand fully what it is... when looking at the Guide on Adafruit it doesn't use a PCA9685 it uses some of the same pins as the power bar.
