Thank you! My multi-meter is coming tomorrow/Tuesday and I just spent an hour yesterday re-soldering the ADJ to find it made no difference. These instructions are exactly what I need (as well as a video I found on testing relays).

Give me a ping - I have more boards coming up, from a small shortage of TRS connectors![]()
Hello,
I have been following the Reef Pi for about six months now and would like to try it out. I am somewhat tech savvy with a few other Pis and Arduinos which work with my 3d-printer and other gadgets. I see your Reef-Pi Pico Controller which appears to still be in beta. I would like to know how to become a beta tester as well as the answers to a few questions. Does the DB18B20 "Stainless" Steel Temperature Sensor and ADJ SC-8 Relay Pack work out of the box or are additional parts (other than the Pi and DB9 cable) needed to make these work? Also, I have read that the PH will not work until 3.0 is this true or is there a way to make it work now? Is the PH sensor not working a result of software or something which will require additional parts to make work? I would also like to automate the dosing of 2 part eventually. Is this supported now? Also is https://blueacro.com/ the place to buy these?
Thank you,

Alright great thanks for your help. I would love to know a status on v3 because pH is a must for me and would be my main concern.I'll take a stab at a couple of these questions, anybody feel free to jump in and correct. I belive both the temp sensor and the ADJ power pack work out of the box. I would consult the master reef-pi thread or some of the other build threads in this section to confirm. pH is a feature coming in the software build of Reef-Pi 3.0. I'm not sure what the progress is on that, again I would consult the master thread run by @Ranjib. That link is the correct place to purchase from.

A firmware issue would suck if it can't be reprogrammed by the user and a different board would be needed. I'll keep an eye on that.I just read through the main build thread and the software developer is working with the board developer to figure out where the bug is occuring. It sounds like it might be a firmware issue on the pH board but that's just my interpretation of the thread. I would keep an eye on: https://www.reef2reef.com/threads/r...troller-based-on-raspberry-pi.289256/page-536 for the latest updates on the project in general

I completely agree and is glad he is up front about it being beta. I definitely like this and can't afford the Apex lol.Yes it would. But I believe the board builder already stated that he was holding shipment of the boards until it was figured out and had a plan in place to update/upgrade the boards already out there. In his defense, he has been open that anybody buying the boards is a beta tester for them
My honest advice is that if you're looking for something that will work out of the box to go with an off the shelf system (probably apex) but if you're looking to tinker and have some fun while getting a lot of functionality then this project is the way to go
Yikes I posted and it asked me to sign in and it apparently posted 3 times! Sorry, hope one of you can clean that up.
Check your ds18b20 wires and connectors closely. Several people have had issues and almost always root cause was a power or data line shorting to ground. Those are small wires. With a full circle of ground around it.Thanks for doing a great job with these boards @theatrus - really happy with how much neater (and more reliable) this setup is compared to my old homebrew Particle photon/breadboard rats nest.
Just a quick with a few observations (from using a Rev. D):
* I'm seeing a fairly significant number of incorrect DS18B20 readings (dozens per day when sampling each minute). I didn't see these previously when the same sensor was wired up to a particle photon. Being honest I've not done any investigation into this yet (doesn't bother me hugely as I've got nothing automated on temperature) but thought it might be worth mentioning in case others see the same. I'll try to get hold of a new sensor at some point and look into it a bit more.
Chris.
