Node-RED easy configurator to read Schneider PowerTags over Modbus TCP

This module is a painless-to-use UI to read data from a Schneider PowerTag energy monitoring environment. This module is NOT a Modbus TCP client, it is meant to be used with node-red-contrib-modbus modules.

How to use

powerTag node

Use the powerTag node to configure which information you want to request from the gateway.

Wire the output of the powerTag to the input of the Modbus Flex Getter.

extractor node

Use the extractor node to convert the values from the modbus response into human readable numbers.

Wire the second output of the Modbus Flex Getter to the input of the extractor.

Single phase

For single phase, msg.payload contains the payload.

Multi phase

For multi phase, all three phases are delivered in msg.payload as an object. {L1: {topic: <L1value>}, L2: {topic: <L2value>}, L3: {topic: <L3value>}}

Example for 10 amps of current: {L1: {current: 10.00}, L2: {current: 10.00}, L3: {current: 10.00}}

Please note, multi phase extractor has not been tested on three phase hardware, it was simulated with code.

Equipment Compatibility

This module has been developed and tested on:

• A9XMWA20 Schneider SmartLink Gateway
• A9MEM1542 Schneider PowerTag
• A9MEM1520 Schneider PowerTag
• A9MEM1560 Schneider PowerTag Flex

This project is still a work in progress. Inspired by the work of hotswapster.
