Plotting graphs with plot.ly service with luup scene using REST API

@samppa just wondering what the numbers at the end of the luup code refers to is 83. 347 etc?
I am reading and what to try to graph my temp/hum.

The numbers are the device id numbers within Vera. They tell the 'Get' command exactly which sensors/devices to pull the data from. They can be found under the 'Advanced' tab under each devices' 'settings'.

I gave up on plot.ly. I can no longer send many data to one graph using their API so I started looking in to ThingSpeak.com that @Dwalt mentioned. I seems like you can use plugins to create graphs with multiple series, seems to work nicely.

@korttoma

maybe try the new Maker channel on IFTTT and send data to google spreadsheet.

then just feed your plotting software (or excel) from the data on your google drive.

Did you get it to work?

@NeverDie ThingSpeak is workin but not plot.ly

Here Plot.Ly has been working:
https://plot.ly/~WhiteRabbit/997

About 6 months or so ago it seemed to stop plotting, and it wouldn't resume even if I rebooted the Arduino. So, I requested all new stream tokens, plugged those into the Arduino program, rebooted, and it has been working since. What I like about Plot.ly is that I can both pan and zoom the data.

I'm presently driving Plot.ly using just the Arduino API. I get the impression I'd have finer grained control if I were to drive it using Python instead.

@NeverDie Thanks for posting, I created a new API key and deleted my old plot and so far so good, it is working again.
Like you I also prefer the UI and plots produced by plot.ly but I'm not convinced by the reliability so far.

Hi Guys

How much work is it in Plot.ly to get in to work

Becuase i test to Copy the examples upper here and put my INFO in the text
But nothing happens, Must i change a lot of thing on the Plot.ly page

I share your concern. It has been a bumpy ride. If it weren't for the pan and zoom UI, I would have tried switching to another free service.

Any one that can explain for me how to get plot.ly to work, I really don't get it :(

korttoma

@Hoffan if you have an APIKey and username from plot.ly all you need to do is to change the following from the first post in this thread:

("urn:micasaverde-com:serviceId:HumiditySensor1", "CurrentLevel", 83) If you don't know what this should be let me know so I can explain further.

You should make sure you remove all the < >

Also I noticed that you can only have one private graph so if you already have one the second one will not get created.
Try changing "world_readable":false to "world_readable":true

Now test your lua code from apps -> develop apps -> test loop code (lua). Do you get any errors?

Hoffan

@korttoma

So if i understand this right, If i have a User and a APIKey, i dont need to do
anything on plot.ly page

I will test to change false to True when i get back home tonight :)

korttoma

@Hoffan no you should not need to change anything at plot.ly your graph should just appear among "YOUR RECENT FILES" on the right when you go to "https://plot.ly/".

Hoffan

@korttoma
Big thanks. Now its working :)

samppa

It seems that plot.ly has new limitations to the free API in their price plan:

Only one free private graph
API rate limits: 50 per day or 30 per hour

Then you have to pay 20 USD/month to get unlimited access.
Damn. There goes the cheap solution.

@samppa Yeah, one another, again. Personally, started with Pachube a few years ago. Gone, a long time ago.

korttoma

Thanks @samppa I was wondering why my plots were not working properly, this explains it.

I converted my code to use ThingSpeak.
It is even simpler to call since the formatting is done on the website. Here is how I use it:

local url = "https://api.thingspeak.com/update?api_key=_YOUR_KEY_HERE_"
result, status = http.request(url,'field1='..HotWaterTemp..'&field2='..HotWaterPump..'&field3='..HotWaterLimit..'&field4='..PumpTime)

On the https://thingspeak.com website you just define the "channel" that receives all the data and copy the example "plugin" and modify it to render your graph.
Quite easy. And free at least so far..

korttoma

I converted some to ThingSpeak now also but I could not get it to work using your example @samppa ,don't know why but this works for me:


local http = require("socket.http")

result, status = http.request("http://api.thingspeak.com/update?key=<API_KEY>&field1="..TankTopp.."&field2="..TankMitten.."&field3="..TankBotten.."&field4="..StatTemp.."&field5="..StatMode.."&field6="..Solpanel.."&field7="..Solpump.."&field8="..CirkPump.."", "run=run")```
