Customize IP:2000/wifi server

[chachew]

Ill have to look around when i get home but where is the RA server housed? I see that it pretty much gets all the layout/images from the reefangel site as well as all the .css and .js, but the server itself is being hosted by the RA arduino board correct?

I was thinking about customizing this and housing it on my own webserver and customizing it with some jquery or something but was wondering if i can directly access the files that are being hosted by the RA unit. Any suggestions?

Cool
I'd love to see what you come up with!!
All you need from the controller is actually the XML data that contains all the data.
http://ipaddress:2000/r99

[chachew]

Oh sweet, all i have to do is parse the XML, easy enough. Does no one really run the server on their own? Figured that would be a pretty popular project..

Thanks Roberto

[chachew]

Roberto, i saw somewhere but i cannot seem to find it now. There was some documentation on http://ipaddress:2000/r12 values and such. I think it was a doc on how to control relays based on the RA webserver XML values. Where can i find that?

On a side note, it would be cool if the ./r99 was stored in a JSON string for easy crossDomain access

You are right about the JSON. I had to create a proxy on the portal server to talk to external controllers.
There hasn't been the need yet.
I'll include in the issues list. It would probably have to be an additional optional feature since we wouldn't be able to fit it in the standard RA memory.
How would the JSON data look like?? Just the values with no labels in a predetermined format? So, column 1 would always be id, column 2 always T1 and so forth?

[chachew]

Yes thats the link that i saw, thanks.

The JSON string would be really simple, something like:
{ "key" : "value", "key2" : "value2", "key3" : "value3" }

Or an array
{ "reefangel" : [ { "key" : "value", "key" : "value2", "key" : "value3" },
{ "key" : "value4", "key" : "value5", "key" : "value6" } ] }

Then you can parse through the string based on the key value or the array index if you go that route. Its also easy to access crossDomain with JSONP

We already do have json data that can be pulled from the server for historical graphing:
http://forum.reefangel.com/status/jsonp ... &filter=t1

I could also easily create a proxy on the webserver to pull xml from controller, parse and return json formatted data just like you posted above without incurring any overhead on the controller code size.
What do you think?

http://forum.reefangel.com/status/jsonp ... &filter=t1

Oh sweet that was going to be my next question, the historic data. Awesome thanks for the info on that! This is some good information to know, i just change out my ID and the filter criteria and boom i get my data! How far back does the data go back, just 7 days like the web chart displays and im assuming that the first value is the epoch date? [1344296765000,80.4] ~ [date(),temp.]

So this would all be server information from the reefangel webserver (reefangel.com) or from the actually RA unit i purchased? Im assuming all the historic data gets stored in a SQL database on your end? Is there no way to directly access the RA webserver locally to get direct access/control of the settings and readings?

IMO it would be super awesome if i could get JSON data returned from the controller, makes life a whole lot easier to access and parse through.

[rimai]

Yes, you can get your own data.
7 days is what you get from MySQL on the RA server.
The controller does not store data, only settings. Well, it does store minimal data to plot the tiny graph, but that's only 24hrs at 12min rate.
So, from the controller itself, you can read and write to internal memory to change settings, such as heater temps, light schedule etc. You can also get the latest data on the XML data you already know (/r99).
Is there any other info you think you could need from the controller itself?
Yes, the data on that link is epoch and data for whatever filter you choose.
You can use any filter from this list:

Ok, thats really all the data i would need i guess because i can control every aspect of the settings with the /rxy commands correct?

Hopefully when i get back from Florida vacation this weekend i will start to put a custom site together for monitoring/controlling my RA

Thanks Roberto

[DrewPalmer04]

I would be interested in seeing how you do this...very cool idea...a walkthrough with pics would be awesome.

Ok, thats really all the data i would need i guess because i can control every aspect of the settings with the /rxy commands correct?

Yes, you can control just about every aspect of the settings with the commands. That's exactly how the apps work (Android, iPhone, Portal). You just have to make sure that your controller uses the internal memory settings and is not hard coded with the values and you are good.

[chachew]

I am currently having an issue with polling the data through a php script.

<?
$file = 'http://www.yoursite.com:2000/r99.xml';
$xml = simplexml_load_file($file);
$json = json_encode($xml);
print_r($json);
?>

If i save the /r99 file and run the script it will work but i think its not working due to the port numbers....other external xml url's work just fine

[binder]

the /r99 does not have ".xml" after it. try removing it and it should work.

[chachew]

the /r99 does not have ".xml" after it. try removing it and it should work.

Yea i have tried both ways and its not currently working. You can actually access the r99 with the .xml extension

...its beginning to look like i cannot get the contents of that file for some reason... argg

[chachew]

OK, i was able to get the file to load, it was actually my hosting company blocking me from port 2000 through their webservers.. So i have a php script get the file and encode it straight to json format and return the string. After that i parse the JSON string and go from there

Looks good progress
Are you planning on a fancy jquery ui?
I'd love to see what you come up with and possibly even put into the webserver js file.
We need a new interface

[chachew]

I really like jquery so im sure it will be written in that.
Are you referring to a refresh on the /wifi interface?

[rimai]

Yeah. that's what I was refering to

[chachew]

Cool, i just got back from a dive trip in south Florida so ill start working on some things this week. Ill keep you posted.

Is there a list that details all of the memory locations and what they control??

It starts at 200 and go to 329.
Each one can be read or written with the command /mb.
So for example you would like to read the hour that StandardLights will turn on, you are going to use memory location 204.
To read that memory location, use command /mb204
To write to that memory location, use command /mb204,10 where 10 is the number of hours in military time.
The trick part is that there are two types of memory. the memory with byte size, which can store values from 0 and 255 and the int size that can store values from 0 to 65536.
The size of the variable can easily be identified by the list above. Mem_B_ means byte size location and Mem_I_ means int size location.
To read and write an int size location, you need to use /mi
For example, you want to read the temperature the StandardHeater function will turn on, you will use memory location 222.
To read that memory location, use command /mi222
To write to that memory location, use command /mi222,775 where 775 is the temperature that the heater will turn on without the decimal point.
I hope this explains a bit.
Let me know if it is still confusing.

Roberto - Are the labels from the Portal available via XML or JSON by chance?
