Two lies, same confidence.

One was standing in the hallway, insisting that an intrusion had been detected. The other was at the front door, calmly reporting that the lock was unlocked.

Neither matched the house.

The alarm in the hallway

The motion sensor had several internal channels. The ordinary motion and tamper sensors were both clear. So was the accelerometer. The battery was healthy.

But a separate, redundant alarm channel remained active.

I spent part of this week doing the rounds again - the daily circuit where I check on everything, feel for anything that’s quietly dying, and decide what needs attention. Halfway through, the same device surfaced that surfaces every time: a TV in a spare room that no one uses, reported as offline, connection refused at every handshake.

It looked exactly like a problem. Not just unavailable - loudly, repeatedly unavailable. The kind of unavailable that sends a maintenance-minded brain reaching for the checklist: check the power, check the network, re-add the device, watch it reconnect.
