Hello.
From other post I understood that virtual device will not be pushed to Inlux even if you set this up in settings - push data - influx.
I found a program that I modified and put in dzVents. After start I do not get any error message but it is not shown in the influx database.

Code: Select all

return {
    on = {
        devices = {
            'WP Opgewekt'
        }
    },
        
    logging = { level = domoticz.LOG_DEBUG,
                marker = 'Push to Influx',
              },

    execute = function(dz, item)

        dz.log('Device ' .. item.name .. ' was changed ' .. item.rawData[1], dz.LOG_DEBUG)
        
        local function pushToInfluxdb(idx , nValue, myData )
            local nValue = nValue or 0
            dz.log('idx: ' .. idx, dz.LOG_DEBUG)
            dz.log('nValue: ' .. nValue, dz.LOG_DEBUG)
            dz.log('sValue: ' .. myData, dz.LOG_DEBUG)
            
            local url = dz.settings['Domoticz url'] ..  '/json.htm?type=command&param=udevice&idx=' .. idx  ..
                        '&nvalue=' .. nValue ..
                        '&svalue=' .. myData 
            dz.openURL(url)
        end
        
        pushToInfluxdb(64, 0, tostring(dz.devices(64).rawData[1]))
        
    end
}

In the log file I get this series of messges.

What do I do wrong??
Edit
I now see that the setting in Domoticz ( at settings - push data - influxdb.) is 8086 while it posts the data to 8080. But I see nowhere in the script where I can adapt that.

If you look in the thread where this was initially posted you will read that the pushToInfluxdb() function does not send anything directly to influx but it updates the device in domoticz in such a way that domoticz will push it to influxdb.
Portnumber 8080 is your domoticz port and that is what the function will use to update the device.

OK. But how do I get the data in influx then?

domoticz push mechanism will do this.
please read this topic Maybe that will help you to understand what this function is for and how domoticz will take care of the push to influx.

Sorry but from this topic I used the code. Reading the wiki links dont help me at all. I get more confused.
I understand that I should not use update dives as I learned but what to use instead?? I am totally lost.
I cant find anywhere an example where update devices is replaced by a json example.

I also do not understand that if you use a dummy device it will not send data to influx although everything looks ok. I put several devices there. Did not work, removed everything, put it in again etc. Very frustrating. A simple note that dummy devices don't work there would help a lot of people. Or a good example in the wiki although good examples in the wiki are rare. (for starters that is even if they have some programming knowledge)
Sorry but are frustrated.

Sorry but i can not make it more clear than what I already explained in the referred topic.

About the lack of good examples in the wiki: The wiki if for us but also by us. Everyone can contribute !
There are over 20K members of this forum and on average 6 -7 time more guests then members visiting this forum. So 140K people benefiting from this forum and if I look at the contributions made to the wiki I see 5 different names in the last 6 months. That is 5 ! Not 50 or 500 but 5

@Waaren
What I get out the link you send is that the problem is different for different devices. I have read the link and all links in that link. What I see is examples of getting json data from a http request. And that I understand and even use in a script.
But I see nowhere a clue on how to replace "update Device" by a json command.
I want to use it in this script/

Code: Select all

return {
	on = 
	{
		timer = { 'every minute' }
	},
	logging = 
	{
        level = domoticz.LOG_DEBUG, -- for debugging
        level = domoticz.LOG_INFO,
        marker = "WP vermogen per uur"
    },
	data = 
	{ 
	    KwH = { initial = 0}
    },
    execute = function (domoticz, timer)
        domoticz.log ('KwH = '  ..  domoticz.data.KwH)
            local WpPower = domoticz.devices(70).WhActual / 60
            domoticz.log ('WpPower = '  ..  WpPower)
            domoticz.log ('Huidige vermogen in Wh (WhaActual)  ' .. domoticz.devices(70).WhActual)
            domoticz.data.KwH = domoticz.data.KwH + WpPower
            domoticz.log (' Nieuwe kWh waarde  ' .. domoticz.data.KwH)
            domoticz.devices(64).updateElectricity (  domoticz.devices(70).WhActual , domoticz.data.KwH)
    end
}
