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

@korttoma said:
@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.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.

@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.
<username>
<APIKey>
<nameForGraph>
<graphTitle>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":trueNow test your lua code from apps -> develop apps -> test loop code (lua). Do you get any errors?
-
@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/".

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. -
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.. -
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")``` -
Like others, I've (regrettably) given up on plot.ly, and gone over to ThingSpeak.
I'm using the following Python code to send values from Domoticz:
thingURL = 'https://api.thingspeak.com/update?api_key=_YOUR_KEY_HERE' url = thingURL + "&field1=%s&field2=%s&field3=%s&field4=%s&field5=%s" \ % (inside, target, outside, lounge, heating) f = urllib2.urlopen(url) f.close() -

I use the base url as the first argument and the field list as the second
r, s = http.request(baseUrl, "field1=XX&field2=XX")Hope that fixes the issue.
Also You have to setup the "Channel" and "Plugin" in the website accordingly and name the fields there.
