Recommendations for the following probes to use with Reef PI;
PH
Salinity
ORP
Not exactly sure if that's a question or a statement... But if it's a question regarding recommendations for probes to be used with ReefPi then:

pH: double junction with BNC connector like an Atlas scientific, Milwaukee, or one sold by BRS. I've got the Milwaukee one from amazon, $40.

As for ORP/Salinity, to my knowledge ReefPi does not support them at this time. @Ranjib will be better suited to answer that.

Due to their high cost, frequent need of calibration and less usefulness (compared to other sensors) I have not tinkered with ec and orp probe.
That being said, I think the ezo ph driver will work as it is for orp and ec as far as reading goes. Calibration and rest needs to be done out of reef-pi using atlas scientific libraries
There you go.

Wonder if any of you gurus could take a new vertex cerebra VII and get it functioning? They are out of business and never finished the raspberry pi based controller. It has a brain, touchscreen and controllable powerbar. I know a guy who got stuck with quite a few and might let someone get one to see what they can do. Just curious ....

We can tinker with it and salvage what's usable. It will be really cool if we can get reef-pi running in one of those. I dont know how many custom components it has, and how easy it will be to get those working with reef-pi. If its a lot of work, its probably not worth , since theres only a handful of these units present. But without testing out, its hard to say how much effort involved

Hi
@Ranjib, @Michael Lane, @BenB
Thanks for all your help, i connected a second PCA9685 as suggested earlier and it is working fine, i was not brave to use 5V from the goby hat since it is the max PCA can handle so i thought it is best to use 3.3V as standard.
woot :) , keep us posted

HELP!!

Got up this morning and the reef-pi is dead. Nothing running. NOt sure when this happened. Was fine last night at around 23H00 but no Alerts from the 05H30 water change that should have happened this morning.

Rebooted the Pi and got the following from the screen connected to it.

Has the card died?

Bought a new card and started it from scratch. All up and running again.

I must say, Raspbian does seem a lot more responsive on my touch screen. Who know how long this card was on it's way out.

I bought two identical cards. Once I'm happy with the setup, I will cut an .img and flash the other card and keep it as a spare. Should have done that ages ago.

Thanks, Des. Out of curiosity besides the tinkering factor do you think this will still be viable option to Apex once the Coralife Hydros 4 is released?
I'm afraid I am not familiar at all with the Apex unit at all. In South Africa, they are prohibitively expensive. I doubt there are more than a handful in the whole country.

Apart from the tinkering factor, that is my main reason for going the reef-pi route.

Probably not too long. It’s not like mechanical drives that die a slow death. SDcards, m2, SSDs usually just go belly up all of a sudden. The new card may just have have better r/rw than the last one.

I have found out one very odd thing.. If I connect led pwm signal wire to raspberry then my ph rises to 12;) I control leds with ir520 mosfet. This was just a test, so I can build new light fixture. So seams like something is making noise hire.

Is there a way to go manually via terminal and delete an ATO from reefpi? Trying to avoid resetting config.

I can't seem to be able to delete ATOs from the UI. I've tried untying them from any equipment and sensors and still won't delete.
