DLMS FOR RASPBERRY PI 3B+ GATEWAY -- 2

We are a small startup located in Yumbo Colombia (town next to Cali) who is working in IoT projects. We are interested in obtaining a software that should run in our Raspberry Pi 3B+ gateway. For reading Smart Energy meters under DLMS protocol. Software should be developed using Node-Red. In particular we are using Microstar P2000-T smart meters, but ideally software should work with a variety of meters. DLMS Software Overview I send more details for the development of the DMLS module Description A Node-RED block must be developed that allows communication with Microstar's P2000T meter or other Smart meters. INPUTS • OBIS ADDRESS or OBJECT IDENTIFICATION SYSTEM: The OBIS address to be requested will be entered, which can be a single address or a set of OBIS addresses, or Meter variables to be read. • Json file: OBIS address information will be provided in a JSON file. The file structure will be defined by the module developer. • Meter Password: The meter password will be included in the input message. OUTPUTS • Json format: The DMLS module must return the information obtained from the meter in JSON format. The data structure will be defined by the module developer. Additional Details • Structure of the JSON input: The developer will be free to define the structure of the JSON input file containing the OBIS addresses and meter password. • Structure of the JSON output: The developer will also be free to define the structure of the JSON output that will contain the information obtained from the meter. This block should be designed to be easily integrated into Node-RED flows, allowing efficient configuration and use by the end user. Certainly, the developers can propose alternate descriptions of their proposed approach for our evaluation. Please provide details on how you propose to demonstrate functionalities of your application.
