Short description

Shelly 1 Gen3 is a small form factor smart switch with potential-free contacts, which allows remote control of electric appliances through a mobile phone, tablet, PC, or home automation system. It can work standalone in a local Wi-Fi network or it can also be operated through cloud home automation services. The device also has improved processor and increased memory compared to its predecessor.

Shelly 1 Gen3 can be accessed, controlled and monitored remotely from any place where the User has internet connectivity, as long as the device is connected to a Wi-Fi router and the Internet.

It can be retrofitted into standard electrical wall boxes, behind power sockets and light switches or other places with limited space.

Shelly 1 Gen3 has embedded Web Interface which can be used to monitor and control the device, as well as adjust its settings.

Main features

• Wi-Fi Connectivity: The device can connect to your home Wi-Fi network, allowing you to remotely monitor humidity and temperature data through a smartphone app or other compatible devices.

• Integration with Smart Home Platforms: You can integrate the Shelly 1 Gen3 with popular smart home platforms, including Google, Alexa, and Samsung SmartThings. This enables voice control and automation capabilities through these platforms.

• Local and Cloud Control: Can function independently in a local Wi-Fi network and can also be operated through cloud home automation services.

• Bluetooth Connectivity: Bluetooth and BLE gateway are available for inclusion purposes, which may be useful during the setup process.

• User-Friendly Interface: The device provides a user-friendly interface with a reset button for manual interactions.

• Improved Processor and Memory: Upgraded with an improved processor and increased memory for enhanced performance.

• Embedded Web Interface: Features an embedded web interface for monitoring, control, and adjustment of settings.

• Wireless Connectivity: The device supports Wi-Fi (802.11 b/g/n) and Bluetooth 4.2 protocols with specified indoor and outdoor range capabilities.

• Dry Contact: Allows switching on and off of lower voltage devices.

• BLE Gateway: Bridge between your Shelly BLU devices and the wider Shelly ecosystem. It receives Bluetooth signals and sends them to the cloud or locally to another non-bluetooth device.

• Wi-Fi Range extender for IoT devices: A Wi-Fi extender is employed to expand the reach of your Wi-Fi network by receiving your current Wi-Fi signal, enhancing its strength, and then transmitting the enhanced signal over a wider area.

• Scripting: https://shelly-api-docs.shelly.cloud/gen2/Scripts/ShellyScriptLanguageFeatures/

• Wide range of integrations: The device can be integrated with 3rd party home systems, documented HTTP API, MQTT(s), Web Hooks over HTTP and HTTPS, UDP

• Schedules: Allows scheduling of complex operations to be executed in predefined time window. Users can specify time windows based on date, time of day, weekdays, hours, minutes and seconds.
