Yes , another Alarm script ...

Same same but different !

You may find some source of inspiration and I will publish in the Wiki, if you are interested and ask for.

- Motion sensor: PIR wireless AND PIR wired sensor (HC-SR501). Search the forum to see my nice case.
- 2 wired siren inside and outside.
- Alarm Mode is a selector with : Off, On, Auto (auto is for auto Arming the alarm based on my system of presence detection of the familly by beacon (bluetooth low energy tracker). Each key of the familly has a beacon. If no beacon is detected inside the house, the alarm is activated.
- The alarm sounds 30 sec after an intrusion detected. And this may be stopped everytime before and after with domoticz switch AND with hardware switch.
- The Alarm may sound only 1 every 3 hours to prevent the neighborhoods to become crazy ...
- The night, special mode : the alarm is always On. (Last TODO, I planned to check a PIR near the chamber, If it detects something before the PIR elsewhere then i will switch off the alarm because a member of the familly wake up.)
- everything on battery (UPC)

Code: Select all

   year = string.sub(s, 1, 4)

nice! I think that is better to build zones with group of sensors and also place security status (arm away/arm home/disarm) inside the script.
I see that most of scripts did not check the status of sensors when they place the alarm. for example I have some z-wave sensors that fail due to bad quality of signal, so if I place alarm without check them I will get after a while an alarm.
Also an extra parameter could be the HOLIDAY mode that if you are on holidays to get an another notification (SMS for example) and check also for any power failure (if intruder had powered off main power of house).

Thank you for your feed back,

place security status (arm away/arm home/disarm) inside the script.

I don't understand. what do you mean ?

And what do you advice in case of power outage ? (I have my domotic + internet box + siren backed up on an UPC. And I can detect a power outage with the upc)
