SwitchBot Hub 3

The central processing unit that handles the hub's computing tasks.

A more powerful CPU enables faster processing, better multitasking, and support for more connected devices.

Random Access Memory (RAM) used for temporary data storage and processing.

More memory allows the hub to handle more simultaneous connections and run more complex automations smoothly.

Internal storage capacity for system files, logs, and local data.

Additional storage space allows for more extensive local processing, longer history retention, and offline capabilities.

A slot for inserting a MicroSD card to expand storage capacity.

PoE port that can provide both power and network connectivity through a single cable.

Power over Ethernet simplifies installation by eliminating the need for separate power adapters.

Built-in audio output for alerts, announcements, or media playback.

Integrated speakers enable voice announcements, alarm sounds, and audio feedback for hub interactions.

Built-in audio input for voice commands or sound detection.

A built-in microphone enables voice control and can detect audio events like glass breaking or smoke alarms.

Range: The 2.4 GHz band offers a longer range, meaning it can cover larger areas and penetrate solid objects like walls more effectively than 5 GHz.

Speed: Generally, 2.4 GHz provides slower speeds compared to 5 GHz due to a lower maximum data rate.

Interference: More prone to interference since many other devices (like cordless phones, microwaves, and Bluetooth devices) operate on the 2.4 GHz frequency, leading to potential congestion and slower network performance.

Range: Offers a shorter range compared to 2.4 GHz and may have difficulty penetrating walls and other obstacles.

Speed: Typically provides faster speeds and higher data rates due to more available bandwidth.

Interference: Less prone to interference as fewer devices operate on this frequency, leading to a more stable connection.

Ethernet is a widely used technology for wired networking, providing a stable and high-speed connection between devices on a local area network (LAN).

Speed: Ethernet can offer higher and more consistent speeds compared to Wi-Fi. Modern Ethernet standards can support speeds from 100 Mbps (Fast Ethernet) to 10 Gbps (10 Gigabit Ethernet) and beyond.

Stability and Reliability: Because it uses a wired connection, Ethernet is less susceptible to interference from other devices and physical barriers, leading to a more stable and reliable connection.

Lower Latency: Ethernet typically offers lower latency compared to Wi-Fi, making it ideal for applications that require real-time data transfer, such as online gaming and video conferencing.

Security: A wired connection is generally more secure than a wireless one, as physical access to the network is required to intercept data.

Bluetooth is a wireless communication technology used for exchanging data over short distances.

Bluetooth enables devices to communicate wirelessly within a short range, typically up to 10 meters (about 33 feet) for most consumer devices.

Z-Wave is known for its low power consumption, making it ideal for battery-powered devices. It supports a mesh networking topology, allowing devices to communicate with each other directly or through intermediary nodes, thus extending the overall network range and enhancing reliability. The protocol supports data rates of up to 100 kbps, suitable for transmitting control commands and sensor data.

A Zigbee Coordinator or Controller is the central device that creates and manages a Zigbee network. It starts the network, selects the Zigbee channel, handles security keys, and acts as the main bridge between your hub and all Zigbee devices.

A Thread Border Router is a device that connects your Thread mesh network to your home IP network (Ethernet or Wi-Fi), letting Thread devices communicate with apps, hubs, and the internet. It doesn't control Thread by itself, it acts as the bridge that enables setup, remote access, and cross-network communication.

A Matter Bridge is a device or software component that makes non-Matter devices (like Zigbee, Z-Wave, or proprietary ones) appear and behave like Matter devices. It translates commands and status between the original network and Matter, so you can control those devices from any Matter-compatible platform without replacing the hardware.

Whether the hub pairs devices from other brands through its own radios or as a Matter controller (Zigbee, Z-Wave, Thread, Bluetooth). Many hubs only pair devices of their own brand, so a sensor that needs a Zigbee hub will not work with every Zigbee hub.

Partially means the hub accepts other brands only in part, for example Matter devices but not Zigbee ones, or only certified Zigbee 3.0 devices. Controlling TVs and air conditioners by infrared is covered by IR, and exposing the hub's own devices to other platforms is covered by Matter Bridge.

Infrared capability for controlling IR-enabled devices like TVs and air conditioners.

IR control allows the hub to operate traditional remote-controlled devices, expanding smart home integration.

Google Home serves as a central hub for a variety of smart devices, including lights, thermostats, cameras, and speakers. It leverages Google Assistant for voice control, enabling users to manage their smart home with simple commands.

Amazon Alexa is one of the most widely used smart home systems, known for its compatibility with a vast array of devices. Users can control everything from smart lights to appliances using voice commands through Echo devices.

Apple HomeKit is designed for users in the Apple ecosystem, providing a seamless way to control compatible smart devices through iOS devices using the Home app or Siri. It emphasizes security and user privacy.

SmartThings is a flexible platform that connects a wide range of devices from different brands, offering a unified interface for control. It supports various communication protocols, allowing for extensive device compatibility.

Home Assistant is an open-source platform that allows for extensive customization and integration of a wide variety of smart devices. It supports a multitude of protocols and brands, making it ideal for tech-savvy users.

Measures ambient temperature in the surrounding environment.

Temperature monitoring helps maintain comfortable conditions and can trigger heating/cooling automations.

Measures relative humidity levels in the air.

Humidity monitoring helps prevent mold growth and maintains optimal indoor air quality.

Built-in light sensor for ambient light detection and monitoring.

Light sensors can automatically adjust device behavior based on lighting conditions and provide environmental monitoring data.

Built-in motion sensor for detecting movement in the hub's vicinity.

Motion sensors enable automated responses to presence detection and can trigger scenes or security alerts when movement is detected.

Maximum number of individual devices that can be connected to and managed by the hub.

Higher device capacity allows you to build larger smart home systems with more sensors and controllers.

Support for ONVIF protocol cameras for universal IP camera integration.

ONVIF support allows integration with a wide range of IP cameras from different manufacturers.

Support for RTSP (Real-Time Streaming Protocol) cameras.

RTSP support enables integration with professional and prosumer IP cameras for advanced surveillance systems.

Support for Node-RED visual programming environment for advanced automations.

Node-RED support enables complex automation logic and integration with numerous third-party services.

Built-in Tailscale VPN support for secure remote access.

Tailscale integration provides secure, encrypted remote access to your hub without complex network configuration.

It keeps working, and can be controlled from inside your own network, when the internet is down: over Zigbee, Z-Wave or Thread through a local hub, a native Matter or HomeKit connection, a documented local API or an official local integration.

A product without local control stops answering during an internet outage and depends on the maker's servers staying online.

Every advertised feature works without a paid plan: app control, alerts, history and the smart home integrations.

Some products put video history, monitoring or their integrations behind a monthly plan that can cost more per year than the hardware did.
