Reef Pi Build

[ScottBrew]

Ok is there a way to add current monitoring to the outlets?

Need to figure out how to replicate something like this https://shop.controleverything.com/...c-current-monitor-for-i2c?variant=25688334347 or have software be able to compare what devices are on vs what the current usage is. I'm not a software guru, so no idea how to integrate either idea into the reef-pi. I have the current monitor on the input to the reef-pi and I just turn devices on or off to see individual power usage.

No I actually scrapped that part of the build. If the power was turned off to the GFCI it tripped and needed to be manually reset so I just used the fused power switch.

That shouldn't happen. What terminals did you hook hot and neutral to, line or load?

This is the plug I used and this is how it was wired. I checked the power cord with a multi meter to make sure the wires were correct.

Ahhh, a plug in style, thought you were talking about a hard wired GFCI. Does (did) it trip when you just unplugged it with nothing plugged in to it? If so, that may be by design.

Yeah that's exactly what it did so I just scrapped it and run everything from a GFCI in the wall.

@ScottBrew This is a bit ambitious for my DIY skills but you might find it interesting.

The fabri-cobbling (nod to AVE), I can do... The designing, not so much, need diagrams ;Bucktooth. I can navigate Linux just fine, edit stuff as long as I have the script to copy from. Haven't played with I2C yet, still have this board to install for my pump speed control and then I can check it out. Maybe this weekend.

Been reading up on the subject just now. https://www.amazon.com/gp/product/B00UT7U982/ref=ox_sc_act_title_1?smid=A34K5WF5Z9R33P&psc=1
https://www.amazon.com/Gravitech-12-Bit-Analog-Digital-Converter/dp/B00VL6AZ2K the current transformers are inexpensive and an ADC I2C board may do the trick. Might have to run it through @Ranjib or @theatrus

@ScottBrew @Diamond1

They also have these

Seems a bit much to be honest the other option I’m seeing.

https://www.amazon.com/CTYRZCH-SCT-...-Transformer/dp/B01C5JL5IY?ref_=fsclp_pl_dp_2

Would love to have this feature. Not super important but it would be neat. I have no idea how to make it work. Lol. Maybe once I start building this thing and learning......

Are you wanting to monitor each device or just overall? For a permanent install, the second option would require one for each device you want to monitor. Currently there is no support for monitoring in reef-pi BUT there are a number of options to turn a Raspberry Pi in to a current monitor. From post #307, https://www.amazon.com/gp/product/B00UT7U982/ref=ox_sc_act_title_1?smid=A34K5WF5Z9R33P&psc=1 these are the same type device, just without the plug and don't open. Plus more compact.

 

[Ranjib]

Shouldn’t be to difficult to through in a filtering circuit or two to prevent that though.

Should be , try and let us know . One of us just has to experiment with it

Yeah I was thinking monitoring of each device or particularly pumps and powerheads. I wouldn’t want it separate though would like reef pi to keep track of it and give me a nice history and such. Again not super important just would be nice to have.

I need to get started building the thing first. Waiting on stuff to arrive currently. And then I need to learn Linux. Never enough time in a day! @Ranjib on a different note are there probes for nitrates, calcium, phosphate, magnesium, etc?

Some , but most are prohibitively expensive or not available in a form factor suitable for home aquarium. New things employ titration based solutions . I think a general purpose titration system will be more doable

I think we ca pn bring adc support in reef-pi , via ads115 breakout from adafruit

Very nice where are these done through so I may order my own? OSHpark?

@speedstar was nice enough to send me one, not sure where they were made but OSHpark can make them for you.

You can download the files here: https://github.com/vandegraaf/Reef-PI_PCBs

Unlikely, oshpark pcbs are purple

 

[Jonathan Troutt]

Well I ordered 10 of them. Since 10 was the same price as 5. So if anyone wants one......

So, this is the pi "hat" then?
