Round function - Help needed

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
}

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.

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.
