reef-pi :: An opensource reef tank controller based on Raspberry Pi.

Maybe I'll turn that function off and reboot. I'm not getting any value out of the adafruit telemetry functions.

I was about to ask what the benefit of the adafruit telemetry was going to be lol

Agree I think this will be a good comparison, since that will be the only change...

Can anyone explain to me how the ATO Alerts is supposed to work? I attempted to test it yesterday and it did not behave like I had anticipated. I set the check interval to be 5 seconds and then the alert interval to be 40 seconds. I also marked that I wanted to disable the ATO on alert. Sticking the water level sensor in and out of the water it would turn on and off my pump. But when I leave it out of the water for more than 40 seconds I never received an alert, it never turned off my pump, and it did not disable ATO at this point. If I stick the probe back in the water then at this point the pump turns off and ATO is disabled. I never received an email. I tried this a few times and never had very consistent results.

How is it supposed to work? I assumed that after the alert interval it would 1. stop the pump, 2. Disable the ATO, 3. Send me an email.

@Ranjib
pH above 7 is negative voltage, the more negative the voltage the higher the ph

pH at 7 is zero volts

pH below 7 is positive voltage, the more positive the number is, the lower the ph

Woot thanks for getting to this before me. Still catching up on a bunch of replies. Ranjib also has one of the very first hand reworked RevC units - I may have made a firmware improvement in the interim but need to check my build log.

If you’re looking for more boards I’m doing 3 more panel builds (12 more boards) this weekend to put more stock into place.

Is this running on a pi zero or full pi? I doubt there should be any differences besides RAM availability, just curious.

Pi zero. The base board only works with pi zero.

Let me test out the scenario you just described and get back to you. You are using 2.0 ?

If your controller dies, you can use the adafruit.io telemetry to get a notification

Pi zero. The base board only works with pi zero.

Base boards work with pi3 as well, but it requires additional effort to mate the parts.

If the controller dies, how does adafruit receive telemetry?

 

[hockeyhead019]

@Ranjib has there been any discussion about power monitoring for devices connected to the relay power strip? I'm curious to keep an eye on it from an equipment function/life cycle aspect.

It does not, but I think you can alert based on absence of data or by some aggregate value that’s going down

That makes a lot more sense. LOL!

On and off. .. I want to get this in reef-pi . I don’t know when , but the hal changes will make it easier. I want to get the ph sorted, followed by clustering and then jump on to these things. Power monitoring, humidity sensor , custom pwm profile are all in my wishlist

Cool! No worries on the time line, there are some plug in solutions I can use for the time being. I was just curious if it was on the radar at all. I have the hat coming from @theatrus so if there is anything I can do to help out with the pH testing let me know!

Looking to make some fill in LED bars with some cheap 3w LED's from china that will be controlled by the ReefPi. I was looking at these inexpensive driver with PWM to work them. Just wondering if anyone has used them, or thoughts if they'd work, and maybe best way to wire them in? Here's the specs...

DC-DC 5-35V To 700mA Step Down Buck Power Supply For Arduino CC/CV Step-Down Power Module PWM Dimming LED Driver
Input :DC 5-35V
Output: 700mA ± 20mA
Drive 1-10 pcs 3W LED
Supports PWM dimming
High level turn off the output
Low level Open the output
LED buck mode to ensure the total total voltage difference is lower than the input supply voltage (2-3V) .
Ultra-small size design (length 3.6cm * Width 2cm)
Constant output current, low ripple.
LED used to ensure the safety, stability, improving the LED light efficiency, reducing the lumen.
Overload, short circuit, overcurrent protection, to ensure the supply security.
Wide input voltage, VIN + is positive electrode input, VIN-negative electrode power supply input.
LED + LED anode connection, LED-LED cathode connection

It doesn't say the PWM signal, but I'm thinking it's 0-6v like a lot of these size drivers are...

I believe I am using 2.2

 

[theatrus]

I’m still testing out the I2C lockup condition with pH on the Pico base board. I can reproduce it using ReefPi but trying to find the most sensible workaround or fix on it. Stay tuned :)

All been working perfectly, but just ran into this hiccup.

@Des Westcott could you post the full output of systemctl, from the screenshot the right side is cut off, would be good to have the complete message.
