Summary

This pull request extends the HWg-STE SNMP plugin by adding support for additional sensor types exposed by HWg devices.

Motivation

The current implementation supports temperature and humidity sensors only.

Some HWg devices also expose:

  • CO2 sensors
  • Water leak detection sensors

These sensor types are currently not monitored by the plugin.

Changes

CO2 support

Added a dedicated CO2 component.

Features:

  • Detects CO2 sensors
  • Supports numeric thresholds
  • Exposes performance data in ppm
  • Integrates with the existing hardware sensor framework

Water leak support

Added a dedicated water component.

Features:

  • Detects water leak sensors
  • Supports common water sensor naming conventions
  • Treats water detection as a binary alarm condition

Status mapping:

normal -> OK
all other states -> CRITICAL
