Not sure where the fault is?
Smart home · routines

Alexa routine runs only sometimes

Intermittent routines usually fail at the trigger, one action, device reachability or timing condition. The activity history shows where the chain stopped.

Smart home · alarms

Connected smoke or carbon-monoxide alarm behaves incorrectly or produces the wrong result

A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. This record isolates connected smoke or carbon-monoxide alarm through local alarm sensor/power versus network, notification and account.

Open record
Smart home · alarms

Connected smoke or carbon-monoxide alarm is not working

A complete failure should be separated into power or eligibility, the external path, and the component itself before any reset. This record isolates connected smoke or carbon-monoxide alarm through local alarm sensor/power versus network, notification and account.

Open record
Smart home · alarms

Connected smoke or carbon-monoxide alarm is unusually slow or delayed

A delay can come from capacity, weak signal, background work, protection or a service wait; measuring the exact stage prevents the wrong repair. This record isolates connected smoke or carbon-monoxide alarm through local alarm sensor/power versus network, notification and account.

Open record

Connected smoke or carbon-monoxide alarm keeps disconnecting or working intermittently

Intermittent behavior is diagnosed by the trigger—movement, heat, load, sleep, distance or time—not by repeating broad resets. This record isolates connected smoke or carbon-monoxide alarm through local alarm sensor/power versus network, notification and account.

Open record
Smart home · alarms

Connected smoke or carbon-monoxide alarm stopped working after an update, outage or hardware change

A failure immediately after a known change should be checked for new defaults, stale pairing, power sequencing or compatibility before factory recovery. This record isolates connected smoke or carbon-monoxide alarm through local alarm sensor/power versus network, notification and account.

Open record
Smart home · alarms

Connected smoke or carbon-monoxide alarm works for one member, room, routine or controller only

A smart-home failure limited to one member, room, automation or controller belongs to that ownership or execution path. This record isolates connected smoke or carbon-monoxide alarm through local alarm sensor/power versus network, notification and account.

Smart home · contact sensor

Door or window sensor says open when it is closed

A contact sensor can misread when magnet alignment, gap, orientation, battery or mounting has changed. Move the magnet near the sensor before deleting it from the system.

Open record
Smart home · voice processing

Google Home keeps saying something went wrong

That response can mean internet loss, account/service trouble, unsupported command or one linked provider failure. A basic time/weather request separates core assistant access from a linked service.

Open record
Smart home · HomePod

HomePod plays music but will not control the smart home

Music playback proves speaker and some network access, while home control also depends on the Home membership, hub state, accessory reachability and account permissions.

Smart home · night vision

Security camera night vision is blinded by a window

Infrared light reflects from glass back into the lens, so an indoor camera aimed through a window may show glare instead of outdoors. Turn off IR or mount outside using an outdoor-rated model.
