Data Logging

[michaldobrotka]

Hi Guys,
Is it possible to log my data readings (temperature and humidity) from Domoticz running on Raspberry Pi into internal folder or to LAN attached NAS storage (no external service). I need just hourly log with time stamp in some kind of text file.I have been searching on forum with no success.
Thanks a lot for suggestions.

what about a script that write a file?
somthing like:

Code: Select all

return {
	on = {
		timer = {
			'every minutes'
		}
	},
	execute = function(domoticz, device)
		local devName = domoticz.devices('myTempHumidDeviceName')
		local fileName = '/path/to/folder/filename.csv'
		local timeStamp = os.date('*t')
		
		fileOut = io.open(fileName, 'a')
		fileOut:write(timeStamp..','..devName.temparature..','..devName.humidity..'\n')
        fileOut:close()
	end
}

Hi emme,
Checked dzVents and changed your script to :

Code: Select all

return {
	on = {
		timer = {
			'every hour'
		}
	},
	execute = function(domoticz, device)
		local devName = domoticz.devices('Terrarium ground')
		local fileName = '/home/domoticz/scripts/Datalogger/Terarriumgroundtemp.csv'
		local timeStamp = os.date('*t')
		
		fileOut = io.open(fileName, 'a')
		fileOut:write(timeStamp..','..devName.temparature..','..devName.humidity..'\n')
        fileOut:close()
	end
}

.csv file was created, but no logs were written after hour.
Am I missing something in script?
Thanks

I didn't check your script logic, but wanted to point out for dzVents to be enabled, the checkbox for dzVents needs to be UNchecked.
