Enabling Persistent Messages on LSMP

Enabling Persistent Messages on LSMP

We're excited to introduce a new feature for the LSMP-2103 (identified by device ID prefix '22', such as 220000) that enhances message reliability through persistence. Unlike standard messages that might be lost during transmission, persistent messages are designed to ensure delivery. If the Cloud doesn't confirm receipt of a message, the system will automatically retry and store the message in internal memory until successful transmission is achieved. This feature ensures continuous data integrity and service quality, even in the face of temporary network disruptions, such as issues with gateways or internet backhaul connections.

How to Activate Persistent Messages:

  1. Ensure your LSMP firmware is upgraded to version 25 or higher, and that you have the latest ZenConfig mobile app installed.
  2. Open the ZenConfig app, access the device configuration, and toggle the Persistent Messages option to "On."


Please Note: The Persistent Messages feature will only be visible and available in the ZenConfig app for devices that are compatible with this function. If your LSMP unit is either not equipped to handle this feature due to hardware limitations or is running on outdated firmware, the option will not appear in the app interface.

Storage Capacity:

The internal memory can hold several thousand messages, which equates to approximately 1 to 10 weeks of sensor data, depending on the message type. This capacity ensures a significant backlog of data can be retained and transmitted successfully.

Optional Settings:

  1. Number of Retries: You have the option to specify the number of retry attempts for each message if it fails to receive Cloud confirmation. To maintain efficiency, we recommend setting this limit to 2 or fewer retries.

Considerations:

While enabling persistent messages enhances data reliability, it may also lead to:

  • Reduced battery life due to the increased energy demand of repeated transmission attempts, particularly in areas with frequent connection interruptions.
  • Lower gateway bandwidth availability, as persistent message retries consumes more network resources.

Consequently, we advise against using this feature in environments with consistently weak radio signals or where a single gateway supports a large number of LSMP devices. This ensures optimal performance and longevity for both the LSMP units and capacity of the network infrastructure.
