Change temperature format

[rkarolek]

Hi
I have two temperature sensors (DS18B20) both sending temperature to domoticz and both are visible as xx.x C.
I made script which read temperature value from both sensor, counting average and change other domoticz device value and.... i have problem
average temperature is visible as xx.xxxxxxxxxxxx C (yes, it has 12 digits after dot), is it possible to change?

its part of code

Code: Select all

	
	local Temp_100_1 = domoticz.devices('Temperatura_1').temperature 				this device have format xx.x C
	local Temp_100_2 = domoticz.devices('Temperatura_2').temperature 				this device have format xx.x C
	local Temp_100 = (Temp_100_1+Temp_100_2)/2
	domoticz.devices('Temperatura').updateTemperature(Temp_100)					but this device have format xx.xxxxxxxxxxxx C
	

sorry for my english

Please upgrade, there was an issue with float format (lengths) which should be solved

sorry for my english

change line

Code: Select all

domoticz.devices('Temperatura').updateTemperature(Temp_100)					but this device have format xx.xxxxxxxxxxxx C

to

Code: Select all

local decimals = 2
domoticz.utils.round(domoticz.devices('Temperatura').updateTemperature(Temp_100),decimals)					this device have format xx.xx C

unfortunatelly it not work
its error log

Code: Select all

i try change for

Code: Select all

local Temp=round(Temp_100,2)
domoticz.devices('Temperatura').updateTemperature(Temp)

but i got other error

Code: Select all

Sorry was to quick and advised incorrect. Try this

Code: Select all

local decimals = 2
domoticz.devices('Temperatura').updateTemperature(domoticz.utils.round(Temp_100,decimals))

didnt work too, but... i change it for

Code: Select all

	
	local Temp_100 = domoticz.utils.round(((Temp_100_1+Temp_100_2)/2),decimals)
       domoticz.devices('Temperatura').updateTemperature(Temp_100)

and its work fine, idk why it doesnt work in one line, anyway tyvm for help
