Which Shelly devices does the LoRa Add-on work with?

With Shelly Gen3 and Gen4 devices such as Shelly 1 Gen3, 1PM Gen3, 2PM Gen3, EM Gen3, Dimmer Gen3 and the Gen4 equivalents. It connects through the proprietary serial interface inside the device.

What is the real range of the LoRa link?

Shelly states up to 5,000 m line-of-sight under ideal conditions. In a city with walls and buildings in between, the usable distance is shorter but still beyond Wi-Fi or Zigbee. The band used in Moldova is EU868.

Does the module work on its own without a Shelly device?

No. It is an accessory with no power of its own: it plugs into a Shelly Gen3 or Gen4 host that supplies 3.3 V. You also need a second paired LoRa module at the other end of the link.

Can I install it myself?

Installation means opening the Shelly host device, which is usually wired to 230 V, and fitting the module onto the serial interface. For this reason CasaSmart recommends installation by an electrician.

Is the transmitted data secure?

Yes. The LoRa Add-on uses AES-CCM encryption and supports unicast, multicast and broadcast traffic, so commands and readings sent over long distances stay protected.

What is the warranty and availability in Moldova?

The warranty is 24 months. The item is currently out of stock; contact the CasaSmart team for lead time and to check which Shelly Gen3 or Gen4 devices you already have so we can confirm compatibility.

About this product

Shelly LoRa Add-on is an expansion module that plugs into Shelly Gen3 and Gen4 devices through the proprietary serial interface and gives them long-range LoRa radio. It works in the EU868 band (plus US915 and 915-928 MHz regional variants where available) and keeps a link over distances of up to 5,000 m, depending on local conditions.<br><br>This is an accessory, not a standalone device: it needs a compatible Shelly host such as 1 Gen3, 1PM Gen3, 2PM Gen3, EM Gen3 or the Gen4 equivalents, supplying 3.3 V at under 150 mW. Data is encrypted with AES-CCM. Fitting it means opening the host, so installation is best handled by an electrician.
