Home Assistant fault monitoring guides.
Sixteen builds for catching a household fault in Home Assistant early: a failing freezer, an aircon that has stopped cooling, a hot-water system, a pump, a water tank, a UPS battery, bathroom extraction, a Bluetooth proxy, the internet link, electricity cost, a frozen sensor, an automation that silently stopped, and a house-wide health score.
Each guide is a self-contained build: example entity names, the detection logic, and the thresholds you calibrate from your own device history before switching notifications on. None of it is a substitute for a proper safety-rated alarm where one is required; it is an earlier warning layered on top.
FAULT MONITORING
Pick the build for what you want to watch.
Each one links straight to the guide, including the FAQ and the commissioning checklist.
Detect a failing freezer before it gets warm
Detect an aircon that runs but is not cooling properly
Detect a hot-water heating fault before the shower
Detect a pump running dry before it fails
Detect pump short cycling from start count and runtime
Detect a water tank leak from behaviour
Catch a weak UPS battery before the next outage
Detect a bathroom extraction fault from recovery time
Find a failed Bluetooth proxy before sensors vanish
Separate an NBN outage from a local network fault
Catch an electricity cost fault before the bill
Detect a sensor that has frozen on a believable value
Detect an automation that silently stopped working
Detect a silent remote shed sensor before you need it
Detect a server cupboard cooling fault early
Build a house health score without hiding faults
Rather we built it for you?
We build and calibrate these against your own devices and history, and wire the alerting so it stays quiet until something is actually wrong.
