Wiser KNX Home Energy Management System (HEMS)

This chapter guides an installer through the setup of the controller to enable energy monitoring in the mobile application.

It requires a system integrator or an installer to know the general setup of the controller, which involves device commissioning and KNX object management.

The mobile application and its energy management provide information about house consumption, solar energy production, actual power flow, etc. It can also give insights into energy costs and CO2 impact.

Required settings and installations:

1. Energy monitoring devices, as described below, have to be installed, connected to the controller, and commissioned:

   Devices	Examples
   Modbus or KNX Energy meters	Schneider’s KNX Energy Meter REG-K/3x230V/16A (MTN6600-0603) Schneider’s iEM3150 energy meter - 63 A - Modbus (A9MEM3150) iEM3155 energy meter - 63 A - Modbus (A9MEM3155)
   Power Tag Modbus	Energy sensor PowerTag Resi9 80A 6xLN Modbus 1-Phase (R9M80X6M) with 80A Current transformers (R9MCT80) More info is available here: Supported Energy Meters. Find out more about creating a Modbus profile in the controller user guide here.
   Power Tag Link and A9 Power Tags	Acti9 PowerTag Link - Wireless to Modbus TCP/IP Concentrator (A9XMWD20) Acti9 PowerTag Link HD - Wireless to Modbus TCP/IP Concentrator (A9XMWD100) Power Tags: A9MEM1521 A9MEM154 A9MEM1561 Find out more about creating a Modbus profile in the controller user guide here.
   KNX actuators with current detection	Switch actuator REG-K/4x230/16 w (MTN647595) Switch actuator REG-K/8x230/16 w (MTN647895) Switch actuator REG-K/12x230/16 (MTN648493)
   Modbus Solar inverters	Currently supported: Kostal Plenticore Solax X3 G4 More info available here: Supported Solar Inverters Find out more about creating a Modbus profile in the controller user guide here.
   Other devices with energy monitoring options supported by KNX and/or the controller	Smart plug Smart socket

2. The Energy plugin has to be installed and configured. It is available in the controller’s Marketplace and is designed to map the energy data from the devices described above.

3. The mobile application is installed on your mobile phone (the latest version available in the Google Playstore and Apple Appstore), and the valid account is linked with the controller.

4. You must set your controller location in the mobile application (see more in Home Management).
