Query P1 database with JSON

[Gingerpale]

Hi,
My current energy script filters the P1 meter log database per year and searches for specific dates in that year.
[url]http://<IPaddr>:<Port>/json.htm?type=command&param=graph&sensor=counter&idx=12345&range=year&year=2026[/url]
It returns the whole year, but filtering for 2026-01-01 it returns:

Code: Select all

{
			"c" : "6409.15",
			"d" : "2026-01-01",
			"p" : "11.8244",
			"v" : "9.91"
		},

So this works but queries a large JSON response.

Since I am only looking for data at one specific date (day of the year), I thought I could also do:
[url]http://<IPaddr>:<Port>/json.htm?type=command&param=graph&sensor=counter&idx=12345&range=2026-01-01T2026-01-01[/url]
However, in this case not all data is present, I get (only showing "result" section below), so "c" and "p" are missing:

Code: Select all

	"result" : 
	[
		{
			"d" : "2026-01-01",
			"v" : "9.91"
		},
		{
			"d" : "2026-01-01",
			"v" : "20.11"
		}
	],

What thinking error do I make?
Ultimately I want to fetch the data of the P1 meter for one specific day of the year (e.g. contract start date).

Any idea's?

What if you range from the contract date till today? You also only see the d and v value?

Another option, use the web gui. Click on your P1 meter, at the top click 'Report', then click on the right month to see a report by day
You ask for yearly data, so you get a year.. you can also query for the last month, has less values

@ waltervl If I range from contract date start till today it also only gives the d and v values back.
@gizmocuz I use this in a Dzvents script to calculate something like total counter = today counter - start counter, so using &range=year is nice as it gives values per day. As my script fetches quite a lot of JSON data every time and I had the issue with the callback function in other post, I figured it would be good to query for less JSON data or for exactly the data I need without fetching all the other useless data and searching through it.
Range felt like a good option but strangely enough it only fetches part of the data I need, actually I need the "c" which it doesn't fetch.
So I just wondered if I made a mistake or anything?
