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

I just have my old Samsung galaxy tab 8 that I leave on a charger and just have the browser open to ReefPi (dashboard default).

Once everything is set I really don't have a lot of need to have the info constantly displayed. And if I do, just VNC from anywhere with an internet connection.

The zetlight lights that work with apex
Is there a way reefpi can replicate the apex signal for the zetlights?

I do something similar

I always have a mobile or a desktop available and my home router has a vpn server so I can vpn into my home network and simply pull up the webpage from anywhere.

Hello,

I just purchased a reef-pi hat goby.

I noticed he also had a module for the Mars aqua. Would this work to control the viparspectra lights?

Thanks

The Mars Aqua Adapter is not designed or tested with viparspectra. My adapater was designed specifically for Mars Aqua to control on/off and dimming without being destructive. As @Bigtrout mentioned, there are variations in the lights, and even the pictures from @AbjectMaelstroM aren't definitive for your lights.

Tag me if you start a build thread, I'll be happy to offer opinions and advice. We can probably figure out a way for reef-pi to drive the lights if you are comfortable opening them up and taking voltage and frequency measurements with a multimeter.

That's a very good question. I'd also like to know the answer.

If it takes 0-10v analog signal then it should be doable. There were a couple of couple in this thread that have done it.

Guess my waterproof temperature probe wasn’t waterproof after all. Seems the DS18B20 worked great for 8 months reading air temp. After being in the tank for about 2 hours it started reading 262 degrees ! Pretty sure the tank isn’t boiling lol! Anyhow , after pulling it out and drying overnight it now reads air temp correctly. Anyone else have something similar happen ? I ordered a replacement. I am running reef-pi 2.3 for what its worth.

I have been experiencing issues with mine for the last few months.. suspecting similar issues, so I just ordered replacements for them.

I am thinking about trying this kind of sealant for the replacements.

But then I'm sure you won't be able to use the standard Apex control plug to the QMaven Range. It's like a stereo headphone jack.

I'm not sure how exactly Mars Aqua work, but by looking at this thrad:

My Reef pi build - Well, my Viparspectra PWM light controller :D

Where is your uln2803? That I think is your problem. You are trying to run the relays directly off of the raspberry pi outputs which draws too much current thru the pi output pins causing the undervoltage error. The uln2803 is part of the power controller for a few good reasons. It isolates...

Looks like Vipars are PWM out of the gate. The issue is that it needs a signal to turn on/off. I believe, and this is without a detailed look at MA light and Mike might be able to speak to this more, they operate in the similar manner.

So you would need something like a 5/12v relay which would get signal from the pie to turn on/off the light, then simple pwm signal from the pi or the PCA to adjust each channel.

I'm out of town for next two weeks, but I should have my replacement Vipar fixture by the time I get back and I can give it a crack then.

Thanks guys! When you said dipped in silicone I was thinking something comparable to Plasti Dip. I think the idea of heat shrink tube and seal up the edges with silicone it a solid approach.

My first one was the lighter weight sensor(not drox type). I potted the entire sensor up to about 1/2 inch of wire in epoxy. Still working about 10 months later. the next two were drox type and went into a freshwater tank with no extra coating.

Belated thanksgiving everyone. I was too busy wrapping up reef-pi 3.0 followed by thanksgiving food coma

I have installed a reef-pi outside in the patio yesterday to monitor outdoor temperature. It was almost 40 F last night. And its raining

Wify made hot chocolate

Now off to the next set of things. Son has a big agenda for the holidays... have to follow his lead here..

As the wise man said , happy wife == happy life

@ Ranjib I noticed a strange behavior in reef pi 3.0.

Is there a reload built in on a timer. Looks like my reef pi reloads on its own every night at midnight. It shows that on the about page and i can see the typical drop in memory usage that a reload brings every night near midnignt

We dont have anything built in that will do it. None of my build experienced this yet with 3.0

and

Theres are many things in linux/raspbian that can cause this. Can you run this and check what was happening during that time:

journalctl --since "2019-11-29 23:55:00" --until "2019-11-30 00:05:00"

Im getting nothing in the logs...strange

Hello

Any News to cut the Temp-graphs ?

 

[pais]

hi everybody, just upgraded to 3.0 from 2.4. First thing i noticed is changements in Atlas ezo circuits management: my arduino is not responding the same way as before. (I use an arduino to emulate the behaviour of an ezo circuit through the i2c communication). Did you remove some character transmission from rpi ? I receive correctly all the "requests" from rpi but no more "transmissions" from rpi. Difference lies in different behaviour of Wire.OnReceive and Wire.OnRequest functions i am not aware of. However thank you all for your great work !

Shoot, Ranjib, I owe you a bill of material on that hat I sent you. I'll get that done shortly. Same with a schematic.

I've got to order some boards for my business in a few days, so I'll probably be doing a fresh revision shortly. The funny part is I have two of mine built-up here and I haven't even tried either one yet. Haven't had time to do much other than get the base Pi OS installed. So if you've got any requests, now is a perfect time.

@Ranjib
Caught this logging real time as it happened. Reef pi fails at 11:59pm every nite since installng. It reloads and works fine.

Heres a copy of what i caught

Im ready to upgrade to 3.0 but I am not sure how to backup the database.
I know its located at /var/lib/reef-pi/reef-pi.db but how do you actually do it?
