How to Choose the Right Sensors
When shopping, pay attention to compatibility—such as Zigbee or wireless protocols—to ensure everything works smoothly. Think about the coverage you need: motion and smoke sensors for safety, climate sensors for comfort. Also check how each device is powered (batteries or plug-in) and whether it supports app notifications. Basic models are fine for small apartments, while larger homes might benefit from networked solutions with several sensors working together.
Your selection will depend on your needs—start with essentials like motion and temperature sensors, and expand your smart home setup as you go. Choosing devices that work with popular platforms like Zigbee or Tuya makes integration much easier.
