What are the differences between the different generations of Shelly products?

Each new generation adds more power, memory, and features:

Gen 1 offers basic control;

Gen 2 (Plus Series, Mini Series, Pro Series) adds Bluetooth, scripting, and better security;

Gen 3 improves performance, adds Matter (starting from firmware version 1.6.0 or newer) and advanced monitoring;

Gen 4 offers multi-protocol connectivity, featuring Wi-Fi 6, Bluetooth, Zigbee, and Matter.

Can I control the device via Bluetooth?

No, the protocol is used only for device inclusion, allowing for quick and easy setup through the Shelly Smart Control app.

For bluetooth control it is required to have another Bluetooth device such as Shelly BLU Button or Shelly BLU Motion to interact.

Additionally, Shelly devices can function as a BLE gateway, bridging Shelly BLU devices to your Wi-Fi network.

Is it possible to use the device without a hub?

Yes, Shelly devices (except for Wave devices) operate independently without the need for a hub. They connect directly to your Wi-Fi network, and you can control them via the Shelly Smart Control app, web interface, or through integrations with platforms like Google Home, Alexa, Home Assistant and Samsung SmartThings.
