Smart Sensors: Choose Detection Before Automation
Decide what you need to detect, how quickly someone must respond, and what should happen if the internet fails. A leak sensor is not a shutoff valve, a motion detector is not always a presence detector, and a compatible radio does not guarantee every feature in every hub. These guides help you compare the complete system rather than a sensor in isolation.
