FAQ

1. Why is my Shelly device not recognizing the Shelly Pro LoRa Add-on?
   Please check the following:

   • Ensure your Shelly Pro LoRa Add-on is mounted securely on a compatible Shelly Pro host device.

   • Confirm that the host device is running firmware version 2.0 or later.

   • Verify that the Pro LoRa Add-on is properly connected to the proprietary Shelly serial interface (used to connect Add-ons to Pro devices).

2. Can multiple Shelly devices transmit data over LoRa via a single Shelly device with a Pro LoRa Add-on? Or do all devices need a Pro LoRa Add-on?

• If you have a Shelly Pro device with a Pro LoRa Add-on acting as a gateway, it can receive data from other devices (including BLU devices via Bluetooth) and forward or process it.
  For example, data from BLU devices (e.g., BLU H&T) can be collected via Bluetooth by the Shelly device with the Pro LoRa Add-on and transmitted over LoRa. This setup requires custom scripting, and template scripts for transmitter and receiver use cases are available. You can refer to the examples in our GitHub:

  • For Shelly device that acts as LoRa gateway and listens to Bluetooth devices: GitHub Link

  • For Shelly device that receives data over LoRa: GitHub Link

• If you want the simplest and most robust setup, it is recommended that each Shelly device that needs LoRa communication has its own Pro LoRa Add-on.

3. Is the Shelly Pro LoRa Add-on limited to a one-to-one connection, or can it support multiple devices?
   The Shelly Pro LoRa Add-on supports flexible communication topologies:

   • It can operate in one-to-one, one-to-many, and many-to-one configurations.

   • You need at least one transmitter and one receiver, but you can also have:

     • One sender communicating with multiple receivers

     • One receiver receiving data from multiple transmitters

     • Multiple transmitters and multiple receivers

   • To ensure reliable communication, it is recommended to avoid multiple transmitters sending data at the same time, as this can lead to radio collisions.

   • Make sure that all Shelly Pro LoRa Add-ons use the same LoRa configuration (e.g., frequency, bandwidth, spreading factor) to ensure proper communication.

4. Can I still use the standard functionality of a Shelly Pro device when it has a Pro LoRa Add-on?
   Yes. The device can simultaneously operate as a LoRa communication point and a locally controlled Shelly device.

5. What is the LoRa Spreading Factor (SF), and how should I use it?
   The LoRa Spreading Factor (SF) defines the trade-off between range, data rate, and airtime:

   1. Lower SF (e.g. SF7) - provides a shorter range but allows faster transmissions and more messages per hour.

   2. Higher SF (e.g. SF12) - increases communication range, but results in longer airtime and fewer messages per hour.

When using multiple devices, set the SF based on the farthest device in the network. This ensures reliable communication for all nodes.

6. Why did my Shelly LoRa Add-on suddenly stop transmitting, even when the sender and receiver were very close?
   This is most likely caused by the LoRa Safety Stop, which is triggered when transmission limits are exceeded:

   • In the EU868, LoRa devices are subject to regulatory duty cycle limits (for example, typically 0.1% per hour per sub-band). This limits how long a device is allowed to transmit within a one-hour period.

   • To protect against misconfiguration, faulty scripts, or unintended excessive transmissions, the Shelly Pro LoRa Add-on implements a Safety Stop mechanism.

   • The Safety Stop is triggered when 25% of the recommended hourly transmission time is reached.

   • Once triggered, the Pro LoRa Add-on temporarily blocks further transmissions, regardless of distance between devices.

   • Transmissions will automatically resume once the hourly usage drops back below the recommended limit.

7. Can LoRa Add-ons and Pro LoRa Add-ons communicate with each other?
   Yes, both add-ons can communicate with each other, provided they use the same configuration.
