# SwitchBot meters and sensors

*SwitchBot / 9 models*

> SwitchBot's meters and sensors are small battery devices that mostly use Bluetooth, so remote alerts, cloud history and Matter all need a SwitchBot Hub. A hub exposes every one of them to Matter, but the platform's own home gateway is still needed, such as a HomePod or Apple TV for HomeKit. The Water Leak Detector connects straight to Wi-Fi. The Presence Sensor works without a hub and links locally to a SwitchBot Bot, Relay or Light. Home Assistant reads all of them over Bluetooth with no hub.
