3. System requirements

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

Required

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

Optional

Smart PIERRE app: control and monitoring from a smartphone or tablet. Not required for basic operation.
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 display and/or gateway for the PIERRE Wave (Zigbee 3.0, 2.4 GHz) network.
Two AAA batteries, or a USB supply through the USB interface. No wiring.

9. FAQ

Q1: Where should the sensor be installed?

At eye level (about 1.5 m), away from draughts, direct sunlight, heat sources and external walls.

Q2: How many sensors do I need?

One per room or zone where you want to measure or control temperature and humidity.

Q3: Does it need calibrating?

Not always. Calibrate if the reading disagrees with a reference thermometer, or if the sensor sits where electronics, sunlight or poor airflow affect it. In the Smart PIERRE app an offset can be set for the temperature and humidity values.

Q4: Where should the humidity sensor be placed?

Where moisture matters most (bathroom, kitchen, cellar), at head height and in free air. Do not hide it behind furniture or in a cavity; it needs airflow to measure correctly.
