I had a calibrated temp probe controller that i used to control heaters before reef pi, i tested the ds18b20 DROK probes against it and my 4 ds18b20 were all within .2 degrees of the calibrated probe, and all within .1 degrees of each other.

If you have doubts. Make an ice water bath, see how close each of them read to 32f.


That's interesting, I did it this morning, and it seems to work as intended. Confirmed my suspension that one of my probes wasn't as sensitive as the other and took longer to get down to the known temp and still wasn't as on, but still within <0.5F

Temp1 seems to acclimate faster and is more "accurate" than two. Might have to grab 2 more probes and run two of the best and others as back up.

Hey, not sure if you already know but if have spaces in your device name, telemetry to adafruit spits back a URL not found error and the feed doesn't update.

I had named my temperature probe "Reef Temperature" and while it did initially create the feed on adafruit IO, it never updated it. I then renamed it to "Reef" and the error went away and the updates started passing.

I'm on 2.5 pi3.

On another note: I also tried 3.0 pre-alpha 2 and the PWM hz function wasn't taking. I would update the PI PWM hz setting in the configuration and reload but the setting never updated, so I reverted back to 2.5.

The adafruit io issue is a regression. I'll file a bug to track this.
I am yet to pull in the pwm fixes that were shipped in 2.5 to 3.0 branch, so that bug is expected. I'll make sure we have it fixed in next 3.0 prereleases.
Thank you so much for testing and reporting these.

I just noticed i have messed up the BOM link during the recent website update. I'll make it visible there.
Darn. I just checked, and most of the items from the list is gone. Not sure if this is due to missing items. Give me some time to consolidate this list again. I have to check first if the links in the individual guides (they are direct amazon links of specific parts) are still intact. If they are, we have to just consolidate them.

How are you guys mounting temp and pH probes in your tanks/sumps?
I’m using a 3d printed contraption. Before that I was using a bracket from intank.

Talking about 3d printing , I have racked up a decent stock of reef-pi enclosures now :-) . In the coming days I plan to improve upon this simple design to make it aesthetically more pleasant and more functional

Can this be done with a raspberry pi 4 and is it expensive? I would love to do an ATO and a doser.

Yes. Whether it’s expensive or not is but subjective . A simple ato might cost around 20-100$ including sensor, pi, power adapter, WiFi /relay based outlets . Since you can choose individual parts the cost can vary a lot. Pi 4 itself cost 50$ while pi zero is only 10-15$

Can it be done through the api?
The number of analog pins are fixed for individual driver. Ph boards have only one pin per driver while Kasa plugs can have one or 6 analog pin (hs110 vs hd300)

At present in my tank ..... when the power came back after failure, my main motor will start first after the 30 seconds my skimmers will start. when my skimmer starts at the time of the main pump ... my skimmer starts to over glow due to water level ... at present to make the 30s delay I'm using time delay relay. ... is there any way I can do this with reef pi. I'm having a separate relay for main motor and skimmer
