of course@Ranjib is it possible to make the current ph pnly have 2 decimals?
I think 4 decimal spots should be accurate enough.of course. We wrote the controller, we can do anything. Lets just think through this, if thats what make sense. I dont know yet. Lets see what other think. I think it should be ok. Just remember i'll be adding ph based action (equipment control etc) and there is a chance (small) that we'll use the ph thing for titrations, so i am cautious what kinda precision we want to aim for.
My certified calibration fluid is only rated to 2 decimals so I don’t think we need more than that.of course. We wrote the controller, we can do anything.

Cheers.As for the higher PH trend ive noticed that the KH guardian that is based off this same type of test states in there manual. That the machine must be 3 feet or less from the water and to not cut the tubing. So maybe it has something to do with the amount of tubing you have. Just a guess though. Im going to be following this I would love to build it. and try it out.
Is there any manual or schematic and installation instructions that you could give me im interested in building one for my tank and I would appreciate it if you had anything that coul help me to understand it a little better. That site that says calkulate is hard to understand but if I had a little guadiance i think I could figure it out. Thanks in advance.Cheers.
The tubing is only short. That thought had crossed my mind. At this stage I think the most likely culprit is the reaction time of the pH probe when subjected to large changes in pH.
Have just built a new test unit. Will post some details later.
The unit itself is surprisingly simple to build.

W00t. If you want to get rid of the old readings , you can delete the current probe, recreate it again in disable state, apply calibration first and then enable it. Otherwise you wont see the daily ph swing in historic trends due to those high un-calibrated values (3000 in range).
What pH probe is everyone using?

I'm going to get a BRS double junction and test against my Hanna pH meter.
@Ranjib Separately - good to see the TPLink support (I use the outlets for various lamps in my house, my kids don't shut lights off and I'm too lazy to get up haha). Can I use the basic 'framework' for those as a starting point for the Digital Loggers web switch? (Basically, it's just 8 outlets accessable via an API to turn off/on).
YesCan those outlets be used in conjunction with the ADJ strip?
I don’t know . I highly doubt this. This one uses a autokey encrypted tcp based protocol, that I was able to understand by going through the nidejs library. We need to know the specifics of control mechanism of that particular vendor. You have such doc?I'm going to get a BRS double junction and test against my Hanna pH meter.

Just saw this. This is indeed, exciting.
Yeah. They use a RESTful API to interact with the controller..I can post a link in a bit..I don’t know . I highly doubt this.

I can test these as well. I have a couple of use cases. Would we be able to tie them to equipment and into macros and timers? I can build an automatic water change system with these...... maybe.Yeah. They use a RESTful API to interact with the controller..I can post a link in a bit..
