Not a bad ideaI will do that this afternoon when I get off of work.
Thanks for checking in on me.
In other news, I had three temp probes successfully working displaying temps within 0.3 degrees of each other for over a week before this latest speed bump.
I have the circuit built for 2 dosing pumps, but I must have something a bit off as they do not work....yet. I am trying to trace what I did to see if I made a simple mistake. Parts for my ATO and pH system should arrive by the end of the month, so I should be set.
Oh yeah, I made the enclosures. One for the Reef-Pi and pumps and associated boards, and another that has a 7 inch display and a 1TB HDD.
Just thinking out loud here, but I might scrap my initial board and start over. I started with the idea that I wanted to control 8 outlets, but now I am planning on getting this controllable 4 outlet device (https://www.adafruit.com/product/2935) if it ever comes back in stock. I think that I have wiring issues trying to use pins from the power switching for doser motor instead. It might just be easier to get a new perma-proto board and start fresh. It would give me a chance to learn to fritz and combine 2x doser pumps, pH, 3x temp probes, the control for the commercial outlet, and the ATO into a single diagram.
The errors in the log indicate the reef-pi is not able to initialize the pca9685 driver . Is i2c enabled? Can you see pca9685 via i2cdetect ?Ok, rebuilt the Pi and am back up and running.
Dosers still do not work, but I think it is a wiring issue that will need to wait until mid-week to fix. Waiting on some new boards.

I don't think a grounding probe should have an impact, but you should be able to get fairly stable readings from the calibration solutions. I'll follow up this weekend with approximate values to expect for the raw readings.I am now having issues with my pH probe. I have a hand held probe as well as a probe connected through Michael Lanes' pH board to his Goby board. Last week everything was working very well. I saw about .5 difference between the hand held pH and the wired probe so I decided to calibrate. I bought 4 each of the 7.01 and 10.0 calibration solution packets and proceeded to calibrate the wired probe. I was very careful to only open the packet the bare minimum to get the probe inside to reduce atmospheric interference and CO2 absorption. I calibrated and now the wired probe is reading all over the place. I know for a fact that my tank is not sitting at a pH of between 2.1 and 5.3, but that is what the probe is reading. I have re-calibrated 3 times and still get wild results.
Is there any information out there on what my raw data should be for a pH of 7 and a pH of 10 so I can verify that my probe is working?
Could a grounding probe have any impact? I just added one of those to the tank as a "just in case" measure.
Standing by for your thoughts.
