Trends API - buuuudzik - 28.05.2016

Is there an API for a new trends mechanism? e.g. for using some average values in scripts?

RE: Trends API - Habib - 28.05.2016

Hi buuuudzik,

I think it must be possible for own values made them via script to write them in new "virtual" GA's, which you can log for trends. So I made it with custom values.

RE: Trends API - Erwin van der Zwart - 28.05.2016

Hi buuuudzik,

Try this:

require('trends')
name = 'my trend name'
dates = {}
dates['start'] = { year = 2016, month = 4, day = 12 }
dates['end'] = { year = 2016, month = 4, day = 13 }
-- resolution (in seconds) is optional
-- default trend resolution is used when not set
resolution = nil
res = trends.fetch(name, dates, resolution)

log(res)
BR,
Erwin

Nice work Erwin, in your first script you can replace IP with 127.0.0.1 and remove "if-json" call.

Hi Pawel,
in this case don't you create .csv file?
Thanks.

No this script creates automaticaly trends attached to objects, way faster then creating them by hand (:

BR,

Erwin

Got it! Thanks.

Hi
This script lacks the aggregate function. Could you update the script? Is there a function to delete all trends via script?

RE: Trends API - admin - 24.09.2019

You can add aggregation parameter to the function arguments and trend parameter table. Possible values are MIN, MAX, LAST and AVERAGE.

To delete a certain trend, replace "save" with "delete" in URL and pass trend ID like this, where 123 is the ID you want to delete.

Code:
data = json.encode({ id = 123 })

Hi

I am using a somewhat minimized version of this script. I have used it many times before, but today it wont work. I get the error 'Host not found'. I was thinking it was because I had set the IP address and password wrong in my first attempt, but no... still after changing, it did not work. Any idea where to look for errors?

I have the script in a Wiser FW 2.7.0 it that is important...

My script is this one:

Code:
require('json')
require('socket.url')
require('socket.http')

-- parameters
daily = 365*24*60 -- 1 day
daily1year = 365*24*12 -- 365 day
daily2year = 2*365*24*12 -- 365 day
year5_d = 5*365 -- 5 year
tag = 'nyNyTrend'

obj = grp.tag(tag)


for _, addr in ipairs(obj) do

  object = addr.address
  alias = addr.name

  trend = {
    object = knxlib.encodega(object), -- object id in db
    name = alias, -- trend name
    type = trend_type,
    resolution = 5, -- every 5 minute
    precision = 2, -- floating point precision
    count_resolution = 365*24*12, -- 1 year
    count_daily = 5*365 -- 5 years
  }

  data = json.encode(trend)
  post = 'data=' .. socket.url.escape(data)
  grp.removetags(addr.name, tag)

  res, err = socket.http.request('http://admin:qSHs5FAcfY@HRdn@192.168.68.249/scada-main/trends/save', post)
  log(res, err)

end

RE: Trends API - admin - 17.06.2022

Host not found is usually a DNS error. Are you trying to do a request to a remove device or to a local one? For local requests you should use 127.0.0.1 as the IP address.

I did use the IP address of the device. I have changed it to 120.0.0.1, and now the error is timeout.

RE: Trends API - admin - 17.06.2022

Not 120 but 127.0.0.1
