We strongly recommend PIERRE Brightness sensors for optimal integration and performance within the PIERRE smart home system. These sensors accurately detect ambient light levels, allowing your smart home to automatically adjust lighting, ensuring energy efficiency and a comfortable environment.
- Compatible brightness sensors: Compatible sensors, such as the BH1750, are essential for automating lighting based on real-time brightness detection. These sensors connect to the PIERRE system using standard CAT6 cables and are easily configured through the PIERRE Partner application. This makes them ideal for both new installations and retrofits, providing flexibility in upgrading existing systems.
- Automation possibilities: In addition to lighting control, brightness sensors can be integrated with other smart devices within the PIERRE system to enable advanced automation scenarios. For instance, they can trigger the closing of blinds when light levels exceed a set threshold, helping to prevent heat build-up, or they can work with HVAC systems to optimize temperature control based on the amount of sunlight entering the space.
- Energy efficiency: This integration enhances both comfort and energy efficiency in your smart home by ensuring that systems only operate when necessary. The precise detection of light levels helps reduce unnecessary energy use, making your home more efficient and improving the overall smart home experience.

What color mean what on Controller LED?
Green – Online:
The controller is online and connected to the network, functioning as expected.
Red – Offline:
The controller is offline, indicating a disconnection from the network or that there is no internet access.
Light Blue – AP Mode:
The controller is in Access Point (AP) Mode, meaning it is broadcasting its own network, allowing devices to connect directly to the controller for setup or configuration.
Dark Blue – AP Mode with Pierre Partner:
The controller is in AP Mode, and it is actively being managed through the Pierre Partner system. This mode is used for more advanced setup or partner-level configuration.
Purple – Searching for IP Address:
The controller is attempting to obtain an IP address from the router or network. It is searching for an internet connection.
Orange – Firmware Update:
The controller is in the process of downloading a firmware update, ensuring that the system stays up-to-date with the latest software and features.
These LED color indicators provide essential information about the controller’s current status, making it easy to monitor its connection, operation mode, and maintenance activities.
Has the device been added to the configuration?
If not: Add it in the PIERRE Partner application.
Check the GND, +5V, SDA, SCL cables, are they properly connected?
If not: Pay attention to the polarity, if you reverse it, the sensor will be damaged. (Must be +5V)
100% sure that the cables connecting the Pierre to the BH1750 are not mixed up?
If not: Find the correct cables, for example, using an “Acoustic Wire Detector with Tone Generator”.
Is the Address PIN on the BH1750 sensor connected to GND?
If not: Connect them.
Are the SCL and SDA checked?
If not: If it doesn't work, try swapping the SDA and SCL pins.
There is nothing else connected to the digital input of the Pierre where the BH1750 is connected.
If so: Remove everything else and leave only the BH1750 connected.
Is there a voltage on the side of the BH1750?
If not: Check the wiring.
Is the distance not greater than 15m?
If so: Use a 'Differential module' to increase the distance.
In which cases should Input and Output be added to the same Controller?
If one Input has influence on the Output they both should be added to the same Controller.
For example in situation when one Motion sensor triggers a Lamp they should be add to the same Controller for best performances.
How should the sensors be wired?
Each sensor (motion, light, contact, etc.) should be individually wired to the PIERRE control cabinet in a star pattern.
