Notify about health state

◀ Go back to main README

Info: This script can not be used on its own but requires the base installation. See main README for details.

Description

This script is run from scheduler periodically, sending notification on health related events:

  • voltage jumps up or down more than configured threshold or drops below limit
  • power supply failed or recovered
  • temperature is above or below threshold

Note that bad initial state will not trigger an event.

Only sensors available in hardware can be checked. See what your hardware supports:

/system/health/print;

Requirements and installation

Just install the script and create a scheduler:

$ScriptInstallUpdate check-health;
/system/scheduler/add interval=1m name=check-health on-event="/system/script/run check-health;" start-time=startup;

Configuration

The configuration goes to global-config-overlay, these are the parameters:

  • CheckHealthTemperature: an array specifying temperature thresholds for sensors
  • CheckHealthVoltageLow: value (in volt*10) giving a hard lower limit
  • CheckHealthVoltagePercent: percentage value to trigger voltage jumps

Also notification settings are required for e-mail, matrix and/or telegram.
