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.
Use cases
Automatic Protection Against Electrical Faults
Prevent damage and hazards by automatically interrupting electrical current during overloads, short circuits, protecting equipment, and reducing fire risk.
Disaster Reaction
Remotely or automatically disconnect power to affected circuits when Shelly Flood Gen4 detects water or Shelly Gas detects a gas leak - helping isolate the area and reduce the risk of further damage.
Timely Fault Notification and Diagnostics
Alerts and logs all on/off events with timestamps and sources manual, remote, trip, allowing quick identification of faulty circuits and reducing downtime.
Remote Monitoring and Control
Enables monitoring breaker status and input voltages in real time from anywhere via Wi-Fi, LAN, or cloud services, providing peace of mind and faster response to issues.
