EMS question about connect

A script written via Lua does not change the value

How do I get it updated at regular intervals?

After luaScriptResourse is executed in cmd, update the value only once at the first time.

module ("templates.PiTemplate", thingworx.template.extend)
    properties.cpu_temperature  =     { baseType="NUMBER",  pushType="ALWAYS", value=0 }
    properties.cpu_freq  =     { baseType="NUMBER",  pushType="ALWAYS", value=0 }
    properties.cpu_volt  =     { baseType="NUMBER",  pushType="ALWAYS", value=0 }
serviceDefinitions.GetSystemProperties(
output { baseType="BOOLEAN", description="" },
description { "updates properties" }
)
services.GetSystemProperties = function(me, headers, query, data)
log.trace("[PiTemplate]","########### in GetSystemProperties#############")
    queryHardware()
--  if properties are successfully updated, return HTTP 200 code with a true service return value
    return 200, true
end
function queryHardware()
local a = math.random(0,10)
local b = math.random(10,20)
local c = math.random(30,40)
     properties.cpu_volt.value = a
properties.cpu_freq.value = b
properties.cpu_temperature.value = c
end
tasks.refreshProperties = function(me)
queryHardware()
end

I want to update the value regularly with a random function.

Help plz

thanks

seonho Cha​: I believe you can create Tasks in Lua which are functions that executes periodically by the ThingWorx Lua framework. They can be used to execute background tasks, monitor resources, and fire events. You can review the example.lua available ( microserver\etc\custom\templates) with the EMS setup package for more detail with an example usage.
