Uplink Parser
A production-ready parser for the uplinks of this device is implemented within the Lobaro Platform. It covers the wireless M-Bus telegrams (including split telegram reassembly where applicable, AES-128 decryption for encrypted telegrams, and OMS-compliant data interpretation) as well as the add-on data of the respective variant, for example Modbus responses or sensor values.
Customers using the Lobaro Platform can utilize this parser directly as part of the platform processing pipeline.
If you are operating a Lobaro Gateway without using the Lobaro Platform, we can provide restricted platform access upon request. This allows you to inspect the parser behavior and use it as a technical reference for your own backend implementation.
