LUA scene running with or without while true do



Dear All,


I'm confused to run scene with or without "while true do" cycle to use scene all triggered command change.

I have the following easy code without "while true do" to change the airfresh working status if the alarm system is on or off. Work without an problem, if the alarm system status ( thrue smart implant input ) is changed the wall plug of the airfresh also changed

Here is the LUA code:

%% autostart
%% properties
34 value
%% events
%% globals

local alarm
local airfreshId = 55;
local airfreshStatus

function airfresh()    
    alarm = tonumber(fibaro:getValue(34, 'value'));
      airfreshStatus = tonumber(fibaro:getValue(airfreshId, 'value'));
    if ( alarm == 0 and airfreshStatus == 0 )
        fibaro:call(airfreshId, "turnOn");
    elseif ( alarm == 1 and airfreshStatus == 1 )
        fibaro:call(airfreshId, "turnOff");
-- Main program



And here is the similar LUA code when I need to switch on or off the bathroom electrical radiator heating. If I use this LUA code without "while true do" cycle and I change the termostat adjustment no any action happened. If I use the same code with "while true do" cycle this work perfect.

%% autostart
%% properties
28 value
29 value
281 value
272 value
%% events
%% globals

local thermostat            -- id:28 radiator thermosztat
local roomtemp                 -- id:29 room temperature
local radiatorheatId = 54;    -- id:54 radiator heating 
local heatingwater            -- id:281 boiler heating water temp
local heatingwaterpump        -- id:272 heating water pump
local tempswitch = true;

function radiator()
    thermostat = tonumber(fibaro:getValue(28, 'value'));
    roomtemp = tonumber(fibaro:getValue(29, 'value'));
    heatingwater = tonumber(fibaro:getValue(281, "value"));
    heatingwaterpump = tonumber(fibaro:getValue(272, "value"));
    if ( (roomtemp - thermostat) >= 0 )
        tempswitch = false;
        tempswitch = true;
    if (
        ( tempswitch ==  true and
          heatingwater < 30  and  
          heatingwaterpump == 0 )
        fibaro:call(radiatorheatId, "turnOn"); 
        fibaro:call(radiatorheatId, "turnOff");
-- Main program
while true do
    fibaro:sleep(60000); -- Wait 1 minute


Can you please advise why I need to run while true do cycle in the 2nd program, if the 1st program run without this cycle perfect ?


Thank you
