YAAS - Yet Another Alarm Script

[emme]

Ok... this is nothing new...
but it's my way to handle alarms and notification.... and I wish to share and ear your opinion about

My setup works like this:
All PIRs, Magnets, Tamper and flood/gas sensors have the same 4 digits prefix (PIR_, MAG_ etc etc)

Based on the Donoticz Security Panel Status it takes actions

Actions are NOT included here.... this script simply update few variables that will trigger other scripts (not yet implemented) for eventually other actions

Probes and Tampers does not conseder the Domoticz Security panel status
(actually the Arm Home status is not implemented yet)

After 2 minutes with no events, alarm resets and restart:

Code: Select all

local PIR = 'PIR_'       -- Prefisso per devices Sensori Movimento
local MAG = 'MAG_'       -- Prefisso per contatti magnetici
local TMP = 'TMP_'       -- Prefisso per TAMPER
local PRB = 'PRB_'       -- Prefisso per sonde (Allagamento e Gas)
local SECSTATUS = globalvariables['Security']   -- Stato impianto allarme
local AllOff = true      -- Switch per valutazione allarme cessati
local DEBUG = false  
local prfPrompt = '>>> [SECURITY] <<< '

if DEBUG and SECSTATUS ~= 'Disarmed' then print(prfPrompt..'Stato impianto: '..SECSTATUS) end 

function timeDiffVar(vName)
    t1 = os.time()
    updTime = uservariables_lastupdate[vName]
    year = string.sub(updTime, 1, 4)
    month = string.sub(updTime, 6, 7)
    day = string.sub(updTime, 9, 10)
    hour = string.sub(updTime, 12, 13)
    minutes = string.sub(updTime, 15, 16)
    seconds = string.sub(updTime, 18, 19)
    
    t2 = os.time{year=year, month=month, day=day, hour=hour, min=minutes, sec=seconds}
    
    tDiff = os.difftime(t1,t2)
    return tDiff
end

commandArray = {}

    if SECSTATUS == 'Disarmed' and uservariables['Alarm_generic_Staus'] ~= '0' then 
        table.insert (commandArray, {['Variable:Alarm_Generic_Status'] = '0' })
        table.insert (commandArray, {['Variable:Alarm_Sirena'] = '0' })
    end

what do you think about?
