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

[Dwalt]

@korttoma

I tried to set up a new graph using the REST API and could not get it to register with Plot.ly. Without any explanation from Plot.ly, I tried sending the same data streams to ThingSpeak.com and it set up with out any trouble. The API is slightly different but just as easy to use. I set up a scene to run every 15 minutes with the following code:

-- Get Light Levels
local LR_LIGHT_LEVEL = luup.variable_get("urn:micasaverde-com:serviceId:LightSensor1", "CurrentLevel", 47)
local BR_LIGHT_LEVEL = luup.variable_get("urn:micasaverde-com:serviceId:LightSensor1", "CurrentLevel", 55)

- - Get Temps
local LR_TEMP = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1", "CurrentTemperature", 46)
local BR_TEMP = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1", "CurrentTemperature", 54)
local OUT_TEMP = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1", "CurrentTemperature", 23)

-- Send data to ThingSpeak.com
local http = require("socket.http")
http.TIMEOUT = 5
result, status = http.request("http://api.thingspeak.com/update?key=Insert Your API Key here&field1="..LR_TEMP.."&field2="..BR_TEMP.."&field3="..OUT_TEMP.."&field4="..LR_LIGHT_LEVEL.."&field5="..BR_LIGHT_LEVEL.."", "run=run") ````

The service has a limited functionality to manipulate your data but the base configuration is easy to tweak and can be made public or private.  See [here for my sample data](https://thingspeak.com/channels/25629).

...plus it is free to use.

Now plot.ly is back up again.
Apparently they upgraded the infrastructure and broke something. Hopefully that does not happen too often..

[korttoma]

Yes, now it is working again. Maybe you should try again @Dwalt ?

@korttoma
I noticed it back online right after I posted my Thingspeak scene. I had not deleted my Plot.ly scenes and they continued to send http requests during the outage and when Plot.ly came back online, my data resumed plotting.

I have both services running right now plotting similar data and I will leave them both running to test reliability and quirks. It seems the time reporting drifts a little in Plot.ly. I am also going to test Beebotte.

[korttoma]

There was an outage again last night. No data uploaded for 3h. Was it just me or plot.ly?

[Dwalt]

@korttoma I got it too.

This post is deleted!

[korttoma]

Did plot.ly change something or did I brake my own ploting somehow? Anyone else having problems?

[Dwalt]

@korttoma

My plots are still working.

[korttoma]

@Dwalt would you mind charing your lua? Remember to remove your username and api key ;)

Here is a nexample of what I'm using and it stoped working on 9th of this month.

local OutTemp = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentTemperature", 229)
local TankTopp = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentTemperature", 174)
local TankMitten = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentTemperature", 179)
local TankBotten = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentTemperature", 175)
local Solpanel = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentTemperature", 28)
local Solpump = luup.variable_get("urn:micasaverde-com:serviceId:SecuritySensor1", "Tripped", 212) * 50
local CirkPump = luup.variable_get("urn:micasaverde-com:serviceId:EnergyMetering1", "Watts", 98)


local ts = os.date("%Y-%m-%d %X")

local http = require("socket.http")
http.TIMEOUT = 8
result, status = http.request("https://plot.ly/clientresp", 'un=useruser&key=keykeyszx&origin=plot&platform=lisp&args=[{"x":["'..ts..'"],"y":['..OutTemp..'],"name":"Ute Temp"},{"x":["'..ts..'"],"y":['..TankTopp..'],"name":"Tank Topp"},{"x":["'..ts..'"],"y":['..TankMitten..'],"name":"Tank Mitten"},{"x":["'..ts..'"],"y":['..TankBotten..'],"name":"Tank Botten"},{"x":["'..ts..'"],"y":['..Solpanel..'],"name":"Solpanel Temp"},{"x":["'..ts..'"],"y":['..Solpump..'],"name":"Sol Pump"},{"x":["'..ts..'"],"y":['..CirkPump..'],"name":"Cirkulationspump"}]&kwargs={"filename":"Varme","fileopt":"extend","style":{"type":"scatter"},"traces":[0,1,2,3,4,5,6],"layout":{"title":"Värme Systemet"},"world_readable":false}')```

I get 2 values correct to the graph but after this it somehow screws up the time axis of the graph.

@korttoma

Here is my code.

This only tracks light level from one sensor. I did have a data outage that lasted 3 days last month (5/24 - 5/27) and I did not notice it at the time so I am unable to determine exact cause. It resumed plotting after 3 days and I assume the error was on plotly's side. Plotly had some 'offline' issues last year as well.

local Light_level = luup.variable_get("urn:micasaverde-com:serviceId:LightSensor1", "CurrentLevel", 47)
local http = require("socket.http")
http.TIMEOUT = 5
local ts = os.date("%Y-%m-%d %X")
result, status = http.request("https://plot.ly/clientresp",'un=XXXXX&key=XXXXX&origin=plot&platform=lisp&args=[{"x":["'..ts..'"],"y":['..Light_level..']}]&kwargs={"filename":"MHLux","fileopt":"extend","style":{"type":"scatter"},"traces":[0],"layout":{"title":"MHLux_Test"},"world_readable":false}')```

[korttoma]

Bingo. You only have one data source. That I can get to work also. I had over 10 different data in one graph and it was working fine but it is not anymore.

@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.

[Dwalt]

@5546dug

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'.

[korttoma]

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.

[BulldogLowell]

@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?

[korttoma]

@NeverDie ThingSpeak is workin but not plot.ly

[NeverDie]

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.

[korttoma]

@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.
