Description

Shelly PRO LoRa Add-on is a galvanically isolated communication module that extends the range of selected Shelly Pro devices with wireless LoRa communication up to 5 km. It mounts on the DIN rail alongside the host device and connects via Shelly’s proprietary serial interface. An external SMA antenna is included and can be extended or upgraded for better coverage — for example, when the device is installed inside a metal enclosure.

Low RF power below 14 dBm and EU868 low-power mode ensure reliable operation without duty cycle limitations under normal use. Two LED indicators (RX and TX) show communication status directly on the device. The add-on supports custom scripting and can work with Bluetooth on the host device to forward data from Shelly BLU devices over LoRa. Note: A minimum of two LoRa modules is required to establish LoRa communication — either two Pro devices with PRO LoRa Add-on or a combination with Shelly LoRa Add-on. Compatible with Shelly Pro 1, 1PM, 2, 2PM, 3EM, EM-50, RGBWW PM and PRO Dimmer 0/1-10V PM, 1PM, and 2PM (firmware 2.0 or later). Use Cases: Street lighting — remote control and monitoring of street lamps over long distances, Agriculture and irrigation — automate pumps and irrigation on remote fields without local Wi-Fi, Parking facilities — schedule or motion-based lighting across large parking areas, Solar installations — monitor and control inverters and pumps across solar parks, Industrial and warehouse — zone-based lighting and equipment control in large halls
