Shelly LoRa Add-on | Long Range Shelly Gen3 & Gen4 Communication The Shelly LoRa Add-on extends the communication range of compatible Shelly Gen3 and Gen4 devices using reliable LoRa connectivity. Designed for long-range automation, it enables secure device communication up to 5 km in open conditions, making it ideal for remote facilities, smart lighting, farms, warehouses, and infrastructure projects. Compact, powerful, and easy to integrate, the Shelly LoRa Add-on helps you control and monitor devices where Wi-Fi, Bluetooth, or standard local networks may not reach. Product Description Extend Shelly Control Up to 5 km with LoRa The Shelly LoRa Add-on is designed to unlock long-range communication for compatible Shelly Gen3 and Gen4 devices. With support for communication up to 5,000 meters in suitable open conditions, this compact add-on helps extend smart automation into areas where traditional connectivity may be unreliable or unavailable. Whether you are managing street lighting, remote irrigation, parking areas, warehouses, or off-grid equipment, the Shelly LoRa Add-on provides a flexible communication layer for Shelly-based automation. It connects directly to supported Shelly Gen3 and Gen4 devices using the Shelly proprietary serial interface and supports custom scripting, allowing advanced users and installers to build tailored automation solutions. Key Features Long-range LoRa communication up to 5 km in suitable open environments Designed for compatible Shelly Gen3 and Gen4 devices Ideal for remote automation where Wi-Fi or Bluetooth is limited Supports unicast, multicast, and broadcast addressing via Shelly Protocol Built-in AES-CCM encryption for secure communication Supports custom scripts for advanced automation use cases Compact add-on design with external antenna support Suitable for smart lighting, agriculture, warehouses, parking areas, and remote facilities Supports EU868, US915, and BR915-928 regions AU915-928 support coming soon Low power mode support for EU868 Common Applications Smart Street Lighting Use LoRa-enabled Shelly relays to control and monitor street lighting over long distances. Adjust schedules, monitor energy usage, and receive alerts for faults or maintenance issues. Precision Agriculture & Irrigation Automate pumps, sprinklers, lighting, and environmental monitoring across remote fields. LoRa communication allows control over wider areas without relying on local Wi-Fi coverage. Parking Lot Lighting Manage parking area lights with scheduled automation, motion-triggered control, dimming, and fault monitoring to improve safety and energy efficiency. Warehouse Automation Control lighting zones, monitor energy usage, and improve automation coverage across large warehouse spaces where Wi-Fi coverage may be inconsistent. Remote Facility Control Monitor and automate equipment such as pumps, power systems, and lighting in remote or hard-to-access locations. Suitable For Residential automation Multi-dwelling buildings Light commercial buildings Government and municipal projects Universities and colleges Farms and agricultural sites Warehouses Remote facilities Smart infrastructure projects Connectivity Wireless Communication: LoRa Device Interface: Shelly proprietary serial interface for compatible Shelly Gen3 and Gen4 devices Compatible Shelly Devices Shelly Gen3 Devices Shelly 1 Gen3 Shelly 1PM Gen3 Shelly 2PM Gen3 Shelly DALI Dimmer Gen3 Shelly Dimmer 0/1-10V PM Gen3 Shelly EM Gen3 Shelly Shutter Shelly Gen4 Devices Shelly 1 Gen4 Shelly 1PM Gen4 Shelly 2PM Gen4 Shelly Dimmer 0/1-10V PM Gen4 Shelly EM Gen4 Specifications Specification Details Product Shelly LoRa Add-on Connectivity LoRa Size 40 x 42 x 11 mm Weight 10 g Mounting Via Shelly's proprietary serial interface Shell Material Plastic Shell Colour Black Power Supply 3.3 V from compatible Shelly device Power Consumption < 150 mW Ambient Working Temperature -20°C to 40°C Maximum Altitude 2000 m RF Bands BR915-928, EU868, US915 AU Band Support AU915-928 coming soon Max RF Power < 14 dBm Range Up to 5,000 m / 16,400 ft depending on local conditions Important Notes A compatible Shelly Gen3 or Gen4 host device is required. Host device firmware should be version 1.6 or later. Range depends on local conditions, obstructions, installation environment, antenna placement, and regional configuration. AU915-928 support is listed as coming soon. Please confirm band compatibility before use in Australia. Some advanced communication use cases may require custom scripting. FAQs Why is my Shelly device not recognizing the Shelly LoRa add-on? Check that the LoRa add-on is securely mounted to a compatible Shelly Gen3 or Gen4 device. Also confirm that the host Shelly device is running firmware version 1.6 or later and that the add-on is correctly connected to the Shelly proprietary serial interface. Do all Shelly devices need their own LoRa add-on? For the simplest and most reliable setup, each Shelly device that needs LoRa communication should have its own LoRa add-on. However, custom scripting can allow a Shelly device with a LoRa add-on to act as a gateway and forward data from other devices, including selected BLU devices via Bluetooth. Can the Shelly LoRa add-on support multiple devices? Yes. It supports flexible communication topologies including one-to-one, one-to-many, many-to-one, and many-to-many configurations. To maintain reliability, avoid having multiple devices transmit at exactly the same time, as this can cause radio collisions. Can I still use the normal Shelly device functions with the LoRa add-on installed? Yes. The host Shelly device can still operate as a standard Shelly device while also acting as a LoRa communication point. What is LoRa's spreading factor? The LoRa spreading factor controls the trade-off between range, data speed, and airtime. Lower spreading factors provide faster communication over shorter distances, while higher spreading factors increase range but reduce message speed and frequency. Can Shelly LoRa add-ons communicate with Shelly Pro LoRa add-ons? Yes, provided they use the same LoRa configuration.
