The decision before the product
| What matters | Buy or skip logic |
|---|---|
| Coverage point | Match the sensor or alarm to the sink, door, smoke/CO location, or entry point it will cover. |
| Alert path | Check whether it is a local alarm, an app alert, or an ecosystem accessory. |
| System fit | Do not buy a platform-specific sensor without confirming compatibility. |
