I have changed the settings from "All" to "Device" which one caused

Error: EventSystem: in 001: [string "commandArray = {}..."]:3: attempt to index global 'devicechanged' (a nil value)

and i have added the tonumber function several times in my code wich caused ...

I have changed the code:

commandArray = {}

if (devicechanged['Tempsensor']) then

local hysteresis = 0.2
local setpoint = 0

if (otherdevices['Modus'] == 'MANUAL') then
setpoint = otherdevices['Setpoint MANUAL']
elseif (otherdevices['Modus'] == 'AUTOMATIC') then
setpoint = otherdevices ...
