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

Can someone who is experiencing the supposed dashboard memory leak use wireshark and post a capture? Ideally, start the capture before you open the dashboard, then we can see what the traffic is like, if there are connections that aren't closing or being reset that should be.

Before you post it...PLEASE please please remove the packets containing your login credentials (if you aren't using HTTPS). I'd also use a filter so that you don't post all the other stuff flying around on your network (use a capture filter (not a display filter at the top of the capture window) of host <reef-pi_ip_address>)

yes. in fact entire UI is backed by reef-pi's HTTP/JSON based api. Anything you do by reef-pi UI can be done by API, and it can be any external program. the API was thoroughly documented for 1.0, for 2.0 i didnt get the time to work on API docs. If you want to do somethig specific, let us know, happy to chalk out the details (in case code is not helpful).
API is what gives us the foundation to do clustering

Any chance you could share what did get written for documentation of API v2? I'm seeing some API v1 endpoints returning 404 though the module is enabled (and running).
Thanks

I agree that it does look pretty good now, however the 60-80% I was getting after leaving the window open for a few days was the main concern.


What version are you using? Also, is that directly from the pi's browser? The usage that I am seeing is coming from my laptop, as I am running a headless zero W.

I'm running version 2.2 with VNC connect on a pi3. I'm running raspbian with the chromium browser.
I just checked it again this morning and it has stayed under 15% memory usage with a significant drop in cpu usage as well. So my conclusion would be that leaving the browser open is where my extra memory and cpu usage is coming from.

@dmola and @Ranjib and anyone else more familiar with this than I am.

Seems like the power methods mentioned with the options wanted are quite expensive. I've not been able to find one for less than several hundred dollars. At that price I believe it has become cost prohibitive for many people. Not sure if it's possible but could we not simply "daisy chain" another Rpi to do what we want it to do?

Something along these lines or similar?

Once again, simply throwing ideas out there because I don't know any better!

The one I have is around $150. Not cheap but lots of bang for the buck. I agree that the 16 outlet model is pretty spendy.

Edit to add: Pretty much any "smart" switch is going to be $$, more features = more $, whether or not they really cost the implementor any additional cash.

The nice thing about reef-pi is that if it's decided that a switch like the DLI will be supported, the option is still there for folks to use the less expensive ADJ models if they don't want to spend the extra money.

Does anyone know what the "Alert on Health Check" option box is for?

Just checked out the open source energy monitor you linked to - it's AC only (makes sense, since it's contact-less, relying on inductive sensing). That won't work on the DC power that (most of) our equipment runs from. A smart switch which can monitor a per-outlet load is most likely the best option if this is to be pursued.

Brain fart - we could do inductive sensing on the output of the 'dumb' switch outlets. Need more coffee.

Gah! Good catch... I missed that tiny useful bit of info. I'll blame my eyesight! ;Watching

See my 'brain fart' comment I appended to that post :)

It’s sets up alerts against high cpu or memory usage

I'm rubbish with updating reef-pi, is there a page maintained for links to latest release with the code to use to update ?

yeah seen that but its not the latest release is it?

 

[dmolavi]

wget -c https://github.com/reef-pi/reef-pi/releases/download/2.2/reef-pi-2.2-pi0.deb - for Pi zero or

wget -c https://github.com/reef-pi/reef-pi/releases/download/2.2/reef-pi-2.2-pi3.deb - for Pi 3.

O.k you inspired me to get back on my reef pie project..thank you for all the work you have and continue to do on this . Best wishes Tj

I may be dumb lol but I cannot view the releases from the browser on my phone. If I go to the same github link via my PC the links for new releases are visible. Took me awhile to figure that out trying to navigate the github website.

thank you very much, that worked and i managed to figure how to install the update

yeah :-/ , some UIs of github are not visible from mobile, unless you explicitly type out the URL/address
