Writing historic value in Managed Counter [Solved]

[lavola]

Hi,
I'm trying to get an overview of how my yearly power (and gas) consumption changes over time. I know now we're working from home most of the time my power and gas consumption will be higher, and I want to see how much it changes.
I do have a script (Thanks @waaren, https://domoticz.com/forum/viewtopic.php?t=30376) which calculates the consumption over the last year (value(current) - value(today - 1 year)) and I now write that in a managed counter. That works just fine. But if I want to see how it evolves over time, I should also get these values into the history log.
parts of my code:

Code: Select all

local powerYearConsumption = dz.devices('Power Year consumption') -- Counter device showing power Consumption
powerTotal = (powerToday - powerLastYear)
powerYearConsumption.updateCounter(powerTotal)

Possible options I see now:
1. Use a custom sensor to register the values. That will keep a history log of all values and will also calculate the daily and monthly values. However, I don't need a value every 5 minutes (or every time I calculate it), I only need a daily value over time.
2. Store the value directly into the history log, which for me sounds ideal. I've found a way to do this using a JSON call:

Code: Select all

/json.htm?type=command&param=udevice&idx=IDX&nvalue=0&svalue=COUNTER;USAGE;DATE

But as I'm using a dzVents script, I'd rather have a dzVents code to do this.
Any way to directly store a historic value into a managed counter using a dzVents command?
Many thanks to you all!

Using this function? (call with updateHistory(id, date, nvalue, svalues )

Code: Select all

-- only available for managed counters
local function updateHistory(id, date, nValue, sValues)
	local url = domoticz.settings['Domoticz url'] ..'/json.htm?type=command&param=udevice&idx=' .. id ..
                '&nvalue=' .. nValue .. '&svalue=' .. sValues .. ';' .. date
   domoticz.openURL(url)
   return
end

Wow, why didn't I think of that?!
Actually not really the dzVents command I was looking for, but creating a function as a Workaround is of course just as perfect

Many thanks for the quick response
Kudos for being so inventive!

Thx. This needs some more thinking but could well be I will implement this as a dzVents method for managed counters. Quite a number of dzVents functions are already implemented in this way.

Dear Waaren,

I tried to use the dzvents (3.1.4) updateHistory function as decribed in the script.
Question: in your example: mCounter.updateHistory('2021-01-22', 10;1777193'), what means 10;1777193; I guess that one of the figures is the value to attach to the date, but the other?
Also I suspect a typo: missing ' beforer 10.

Anyway, I've created a managed counter (water) and launched:

dz.devices('VS_water').updateHistory( '2021-02-06','4.6' ).

As the result, the counter indicates: 20.210 m³ and nothing in the device log.

Thanks for your answer.

Also I suspect a typo: missing ' beforer 10.

Is indeed a typo. Corrected now

If you use this in your script (replace 783 with 'name' or idx of your device)

Code: Select all

        dz.devices(783).updateCounter(12345678 ) -- this sets the counter on the utility tab
        dz.devices(783).updateHistory( '2021-02-07','11;345678' ) -- this updates the long term log = one value / day  = table meter_calendar
        dz.devices(783).updateHistory( '2021-02-07 00:45:00','0;345678' ) -- this updates the short term log. Can be many values / day  = table meter   

You will get this in the database

Code: Select all

sqlite> select * from meter_calendar where devicerowid =783;
DeviceRowID|Value|Counter|Date
783|345678|11|2021-02-07

sqlite> select * from meter where devicerowid =783;
DeviceRowID|Value|Usage|Date
783|0|345678|2021-02-07 00:45:00

and this in the GUI (utility tab)

Hi Warren, thank you for all your great work for this community.

Did this updateHistory for counters get removed since your post here? It's giving me nil-errors when trying to use it
