Goal

Set up an LXC container with a Node-RED function. A 7KN Powercenter 1000 data transceiver is integrated into Node-RED, which can be queried via Modbus TCP. Additional end devices can transmit data to the Powercenter via the energy monitoring system and be queried via Modbus.

Prerequisites

  • NetModule Wireless Router with wireless connection
  • NetModule Software 5.0.0.100 or newer
  • A license is required for the LXC container
  • Not available for legacy products NB1600, NB2700, NB3700, NB3710

The wiki was tested with router software 0.0.0.0 and the LXC container with Debian armhf bookworn.
