I bought an Emergy’nX: step-by-step commissioning

A new Emergy’nX is commissioned in nine steps, from the electrical cabinet to energy management: wiring, adding it to Can’nX Cloud, opening the application, describing the building, declaring the equipment and its KNX addresses, then setting up load shedding, solar surplus and tariff periods. Follow them in order: each guide ends with a link to the next step.

Before you start

Room for 2 modules on a DIN rail and a 9-30 V DC power supply of at least 2 W.
An RJ45 cable to a switch or the Internet box, with Internet access.
A Can’nX Cloud account allowed to create a project and add a gateway to it.
The characteristics of the grid connection and of the electricity contract: phase type, maximum apparent power, energy plan, prices and off-peak schedules.
The KNX group addresses and their DPTs validated for the installation, or the Modbus values: grid meter, solar production, battery, measurements and commands of each piece of equipment to control. For a Huawei inverter, its IPv4 address, its port and its Modbus identifier (Slave ID).

Commission the Emergy’nX, step by step

Wire the gateway to the KNX bus, the power supply and the Ethernet network. Note the MAC address and serial number before closing the cabinet.
Add it to a Can’nX Cloud project with its QR code, or with its MAC address and serial number, then start its initialization: about ten minutes, with the gateway powered and connected to the Internet.
Open Emergy’nX from Can’nX Cloud with the project’s Emergy’nX button, and generate the permanent link to hand over to the customer.
Describe the power network: phase type, maximum apparent power, Basic, Off-Peak or Tempo energy plan, then grid meter measurements over KNX or Modbus.
If the site has solar panels or a battery, configure production and storage through the KNX bus or Modbus, or through a Huawei inverter.
Create the equipment to control: heating, hot water, pool, air conditioning, ventilation, lighting, EV charger. Its fields depend on the type: see the characteristics by type and, for a charger, the IRVE configuration.
Map its KNX measurements and commands in the Monitoring and Control tabs, with the group addresses and DPTs validated for the installation.
Set up load shedding and solar surplus: threshold levels in watts, delays and commands sent to each piece of equipment.
Set up the tariff periods: equipment to start during off-peak hours, and to restrict during peak hours and the red peak hours of Tempo days.

Check the commissioning

In the gateway list of the Can’nX Cloud project, the icon in the Online column is green.
In Emergy’nX, the top bar shows the project name and the Connected indicator.
The dashboard shows the Solar, Battery, Grid and Building power values, and Equip. shows the cards of the equipment created.
From an equipment card, an ON or OFF request acts on the device: see the Auto, OFF and ON guide. Watch the device itself, then go back to Auto.

Depending on your installation

The general meter gives the building’s total consumption, calculated or measured on site.
The weather location places the site by its GPS coordinates.
Presence/Absence and Summer/Winter feedback then allows control variants.
EV chargers are monitored in the IRVE dashboard.
Install Emergy’nX on the customer’s devices from the permanent link: computer, iPhone or iPad.
History and measurement export are in Chart’nX.

Troubleshooting

For an offline gateway or an abnormal LED, see Emergy’nX wiring. Emergy’nX questions and troubleshooting answers the other frequent cases: menus hidden by TV mode, sections limited to the demo, Conso or Equip. missing, ON with no effect. If the problem persists, write to support@can-nx.com with the gateway name, its serial number and the step reached.
