3. System requirements

Image

The PIERRE Wave (Zigbee 3.0, 2.4 GHz) system consists of the following components.

Required

  1. PIERRE Wave products: switches, modules, sensors, thermostats and other devices. They connect wirelessly to the gateway.
  2. Gateway: a PIERRE display and/or gateway. It links all PIERRE Wave devices and handles the communication with the app.

Optional

  1. Smart PIERRE app: control and monitoring from a smartphone or tablet. Not required for basic operation.
  2. Router: gives the gateway internet access for remote control.

Operation: the gateway connects to the router by Wi-Fi or LAN. PIERRE Wave products communicate wirelessly with the gateway in both directions: commands are sent and status updates are received through the Smart PIERRE app.

What you need

A PIERRE Wave (Zigbee 3.0, 2.4 GHz) gateway: a PIERRE display and/or gateway.

Two runs. Mains into the module is the line in and the switched line L1 back out to the fitting, all at 1.5 mm². The wall switch is looped on 0.75 mm²: common and S1. Do not bring a neutral to the module: this variant has no neutral terminal and does not act as a Zigbee repeater.

7. FAQ

Q1: What should I do if I cannot configure the light module?

  • Check that the module is powered.
  • Make sure the PIERRE Wave gateway (PIERRE display and/or gateway) is online.
  • Check the wiring against the diagram.

Q2: What loads can be connected to this module?

Lighting loads such as ceiling lamps and panel lights, within the rated load given in the specifications.

Q3: What happens if the Wi-Fi or internet goes down?

The module keeps working locally. You can still switch the light with the wall switch and control it from the PIERRE display and/or gateway; only remote access from the app is unavailable.

Q4: How do I reset the module?

Either toggle the connected wall switch 5 times, or press and hold the reset key for about 10 seconds, until the indicator light flashes.

Q5: What happens during a power cut?

The module keeps its last state and comes back when power is restored.

Q6: What size wall box does the module need?

See the Product Size section. The module fits behind the switch in a standard wall box; a deep box makes wiring easier.

Q7: What is the difference between the neutral and no-neutral modules?

Modules with a neutral also act as Zigbee repeaters and strengthen the network. Use the no-neutral module where no neutral is available at the switch.

Q8: Can any switch or button be used?

Yes. Any standard wall switch or push-button can be connected to the S inputs.

Q9: Does it support multi-way switching?

Yes. See the diagrams in the Wiring Instructions and Diagrams section.
