Interesting,
I am planning to drive the dosers with ph probe feedback at the end.
I think the rj11 based control works same as kessil controller. But not sure. Is this a jebao doser ?
I plan to implement programmability (this is similar to feed mode) as part of the 2.0 release. I am still brain storming on the type of interface.

What salt you went with?

Yes the jebao doser which by their own literature is not meant for controller use.

Salt is DD h2ocean bought from marine depot. About the same parameters as the blue bucket from red sea when mixed to 35ppt.

Someone is super happy to have a Reef-Pi Perch to enjoy some through the glass hunting lol ignore the cloudy water, just dosed the tank but this is definitely his new favourite spot

Hi
I have cut a new release of reef-pi , 1.4.
This release contains couple of important changes:

1. pH sub- system. reef-pi now has ph monitoring capabilities. Users can now add ph probes (more than one), calibrate them through the UI, and configure them to monitor tank ph at a fixed interval and alert based on it. This new subsystem likely to see some changes, like equipment control based on ph etc. But anyone wants to monitor ph, should be up and running.
2. Camera sub module received a lot of new updates. Notably an image browser UI and streaming video UI using motion.

There is no doc on the new features yet, they;ll come in due time, if you are planning to use any of them, let me know , I can share some details, but they should be intuitive mostly. pH probe details are mostly covered by atlasscientific documents itself
release builds can be found in usual location: https://github.com/reef-pi/reef-pi/releases/tag/1.4

Awesome! Thanks for the continued support and build. Time to order some pH supplies. Just the chip and probe?

At a minimum
- pH probe
- ezo circuit
- Famale bnc connector

Its good to have some sort of calibration solution, does not necessarily have to be atlas scientific ones.. I think the probe can also be from different verndor, but I have not tried anything else yet, so cant confirm. ezo circuit have to be from atlasscientific, thats the part reef-pi depends on.

 

[Jean-Pierre Renaud]

Super !

Quick question, can I simply upgrade with the upgrade command in ssh?

 

[Ranjib]

I went with the pH kit, which comes with probe+ezo+bnc connector + 3 calibration solution + storage solution and cost 180$. I have not checked how much each of them individually will cost. After couple of months of testing, I 'll try to build a cheaper version (probably swap out probe and bnc connector) that will bring down the cost to below 100$.

 

[ReeferMadness88]

I’ve got a couple China probes that I threw into my last order. I’ll pick up a ezo chip for sure, probably the atlas probe as well to reduce the risk of it not working ha

Yes. You mean this one:

[Jean-Pierre Renaud]

Yes, i was reading that page exactly lol

another question.. i did the mistake of not writing down all my GPIO pins, and my PI3 is kinda in a no reach place lol
can i find the info on waht GPIO i have on what relay with a ssh command before i wipe it all off ?

Do I have to buy an EZO circuit for each ph probe?

Yes .

 

[Ranjib]

Yes .

And probably a voltage isolator as well

reef-pi UI should show them

 

[Jean-Pierre Renaud]

reef-pi UI should show them

here is a screenshot of mine version 1.0

Hmm.. can you run this command

curl -u <user>:<password> http://<reef-pi IP>/api/outlets

change user name, password , and IP to your setup, for example

curl -u ranjib:password http://10.0.0.17/api/outlets

Should show the pin numbers

 

[Jean-Pierre Renaud]

got it working !
[{"id":"13","name":"AC1","pin":6,"equipment":"39","reverse":true},{"id":"14","na me":"AC2","pin":5,"equipment":"37","reverse":true},{"id":"16","name":"AC3","pin" :19,"equipment":"36","reverse":true},{"id":"22","name":"AC4","pin":13,"equipment ":"38","reverse":true},{"id":"23","name":"LED 1","pin":21,"equipment":"34","reve rse":true},{"id":"24","name":"LED 2","pin":20,"equipment":"35","reverse":true}]

 

[Jean-Pierre Renaud]

OK i got it, i was using the ssh password not the reef-pi user and pass

When you're free can you take a pic of the ph setup on your perma board/breadboard? Thanks!
