The plugin is based on pimatic-alarm which is a very neat and powerfull solution to realize a simple alarm system with pimatic sensors and actuator devices.

The new pimatic-alert plugin was build to replace my multi-instance alarm system which required 83 rules to maintain configuration, states and actions of (HomeduinoRF-) contact/PIR sensors (27) and switch devices (8). The system works fairly reliable but administration and change management is painful and error-prone.

This plugin provides an AlertSystem device which can be easily configured through the mobile frontend. Many devices, rules and actions required by such kind of alert systems are configurable through the controller device. The alert system can be reconfigured on the fly even without restarting pimatic. It's also simple, to maintain several alert profiles (day, night, vacation, etc.) and activate them on demand.

Once you setup the alert system you can easily react on alert events with simple rules like:

when alert-switch is turned on then log "alert triggered by
$alert-trigger at $alert-time" and turn alert-switch off after 5 minutes

Use the sample configuration from github to start playing on a test system.

An alert system is build from the following components:

  • Sensor Devices: most probably something like HomeduinoRFPir or HomeduinoRFContactSensor to trigger an alert.
  • AlertSystem: main controller device to enable/disable the alert system
  • AlertSwitch: main switch turned on by the sensor trigger devices
  • Rules: to do something when an alert is triggered ...

The alert switch as well as some runtime variables are generated automatically in the background with the following pre-defined IDs (where ALERT stands for the ID of the AlertSystem device):

  • ALERT-switch: AlertSwitch device triggerd by sensor
  • ALERT-enabled: EnabledSwitch reflecting the state of the system
  • ALERT-state: VariablesDevice to be used in the frontend
  • $ALERT-trigger: the device that triggerd the alert
  • $ALERT-time: the timestamp of the last update
  • $ALERT-reject: device that caused a rejection (see below)
  • $ALERT-error: some error descriptions

Set the autoConfig option to false if you don't want the plugin to generate devices but create them manually.

In adition their are some optional properties which may be useful for your environment:

  • remote: additional switch which is kept in sync with the system switch. Can be used to enable/disable the alert system via the mobile frontend and an optional HomeduinoRFSwitch remote control

  • switches: a list of additional switch devices that will be automatically turned on when an alert is triggered (and turned off when disabling the alarm system) without the need of additional rules

  • required: sensors marked "required" are checked for a valid state if you try to turn on the alarm system. The activation will be rejected if, for example, a contact sensor is open. You have to close the door/window first before activating the alert system ;-) If you use this feature (can be disabled with the checkSensors option) make sure to use the ALERT-enabled switch to trigger actions on enabling the alert system. The controller switch may immediately switch back to off if the activation is rejected but fires your rule by accident.

Create an AlertSystem device which is the main control switch to enable/disabe the alert system and references the sensor devices and actuators of the system. The device provides an "autoConfig" option to generate required slave devices and runtime variables in the background.
