Round function - Help needed

[areg]

Hi,
I need to use the round function to round the PM2.5 value to an integer.
I used code:

Code: Select all

rreturn {
	on = {
		devices = {'airly'},
	
	},
	
	execute = domoticz.round('PM2,5 Norma',0)

	end 

}

However, it does not work.
Device name: Airly
Value: Pm2.5 Norma

Please, tell me what I'm doing wrong.
Thanks

I would assume the round function needs a value and you are feeding it with a sting which also contains regular characters.

Please begin with reading the introduction and getting started of the wiki
After that try this

Code: Select all

return {
   on = {
      devices = {
         'airly'}
      }
   },
   
   execute = function(domoticz, item)
      if (item.state == 'On') then
         domoticz.log('Hey! I am on!')
         domoticz.log('rounding now 2.23435 to 2 decimals .... : ' .. domoticz.utils.round(2.23435,2))
      else
         domoticz.log('Hey! I am off! ; No rounding today')
      end
   end
}

Can you show what's in the log ? And try this one.

Code: Select all

return {
   on = { devices = { 'airly'}},
   
   execute = function(domoticz, item)
      if (item.state == 'On') then
         domoticz.log('Hey! I am on!')
         domoticz.log('rounding now 2.23435 to 2 decimals .... : ' .. domoticz.utils.round(2.23435,2),domoticz.LOG_FORCE)
      else
         domoticz.log('Hey! I am off! ; No rounding today',domoticz.LOG_FORCE)
      end
   end
}

Script

and logs


it doesn't show any errors but it doesn't work
I will add that data from airly is sent via http to the Nextion display.

I need the data from the first row (25,0)to be sent in the second row as a whole number (25).




This is the way values without rounding are displayed.

Is it possible to do?

Is it possible to do?

It is not clear to me what you want to do based on the information you provided. Is this value that you want to round in a device or in a variable and where do you want the converted value. In the log, -in a device or in a uservar.
Please elaborate.

I want the percentage value of PM2.5 (airly, unit 11)to be sent after rounded via http. Currently it is eg 32.00 and I need 32.
