I just remembered where I have another script with variable number of data points.
I use this:

    				    local response=item.json.result
				        for datehour,value in pairs(response) do
				            domoticz.log("solar forecast date "..domoticz.utils.stringSplit(datehour)[1].." hour "..domoticz.utils.stringSplit(domoticz.utils.stringSplit(datehour)[2],":")[1].." value "..value,domoticz.LOG_INFO)
				            local previousHour=domoticz.utils.stringSplit(domoticz.utils.stringSplit(datehour)[2],":")[1]-1
				            if previousHour<10 then 
				                previousHour="0"..tostring(previousHour)
				            else
				                previousHour=tostring(previousHour)
				            end    
				            domoticz.log("previousHour "..previousHour)    
				            if value>0 then
				                sensorDateHour=domoticz.utils.stringSplit(datehour)[1].." "..domoticz.utils.stringSplit(domoticz.utils.stringSplit(datehour)[2],":")[1]..":00:00"
				                sValueStr="0;"..value
				                domoticz.log("sensorDateHour "..sensorDateHour.." sValueStr "..sValueStr,domoticz.LOG_INFO)
				                domoticz.devices(idxSolarForecastCounter).updateHistory(sensorDateHour,sValueStr)
				                if sensorDateHour==currentHR then
				                    domoticz.devices(idxSolarForecastCounter).updateCounter(value)
				                end    
				            end    
				        end

Hello willemd
Thanks for you reply.
I will have a look into later - for the time being I'm trying to adapt your script to retrieve the data for 2 or 3 production types for which I'm sure there are 24 values. This will take some time because of my limited skills....
Btw I have some very basic questions:
- I understand for each production type I need to create a "device". But do I need to create also a "hardware"?
- If I have 3 devices (representing 3 production types) how to I display them in a single log (i.e. with 3 curves)?

In advance thanks a lot for you valuable help.

You can use either an existing or create a new hardware setup of the type "dummy (does Nothing, used for virtual switches only)." and then create your devices linked to that hardware.

To display 3 devices in one graph you will have to use dashticz.

Hello willemd
Thanks for your reply

I could create the devices for each production type creating a hardware as "dummy" and each device as "counter"

But in your script you have also a device called idxCurrentHourIndicator.

How did you create this device?

PS: for the time being I want to run the script which only gets the XML data (i.e. processing of the responseKey is empty)

@willemd,

Thanks for sharing the script I was looking for! However, I am amazed at the script's output. I created a user variable VAT (integer 21) and a user variable energy tax (string 13.2).

I know the option to set a divisor. But I don't understand the result of the 2 counters on the right?

Thanks in advance.

You need to adapt the counter divider on the managed counter to 100000.

The first counter is excluding tax (red line below), the second is including tax(blue line below). Both show the full list of available prices.

The third counter only shows the tariff of the current hour and is used as a sort of arrow in a dashtic graph to highlight the current hour, see the yellow line below in the graph.

Here is also the graph definition

Code: Select all

blocks['graph_ElPrice'] = {
    title: 'Dynamic El Price',
    width:12,
    height: '260px',
    graph: 'line',
    steppedLine: ['before','before','before'],
    buttonsText: ['last hours','today',''],
    devices: [177,179,184],
    beginAtZero: true,
    customHeader: 'devices[184].Data+" incl taxes"',
    range: 'today',
    legend: false
}

I could complete my script after having solved a Domoticz crash:
