# Package: Node-RED Health Checks
|
|
# File: health_checks.yaml
|
|
# Version: v1.2.0
|
|
# Date: 2025-08-25
|
|
#
|
|
# Purpose:
|
|
# Monitors the Node-RED Panda instance through independent HTTP and MQTT health
|
|
# signals and combines them into one connectivity status.
|
|
#
|
|
# Behaviour:
|
|
# - Polls the HTTP health endpoint every 30 seconds with a three-second timeout.
|
|
# - Tracks the MQTT birth/will topic with QoS 1 and a 180-second expiry.
|
|
# - Reports the combined check as available when either source is available.
|
|
# - Reports the combined check as connected when either source is connected.
|
|
#
|
|
# Dependencies:
|
|
# - Reachability of the configured Node-RED HTTP health endpoint.
|
|
# - Home Assistant MQTT integration and the Node-RED birth/will publisher.
|
|
#
|
|
# Version History:
|
|
# - v1.2.0 (2025-08-25): Reduced MQTT expiry to 180 seconds and clarified the
|
|
# combined HTTP/MQTT sensor name.
|
|
# - v1.1.0 (2025-08-22): Split HTTP and MQTT probes and added a combined sensor.
|
|
# - v1.0.0 (2025-08-21): Initial Node-RED health-check package.
