4. Configuration et installation
4.1. Note importante concernant la compatibilité
The SAMOTECH SM301Z is a Zigbee device and requires a compatible Zigbee hub for operation. It is not a Wi-Fi device and cannot connect directly to your Wi-Fi network. Ensure you have a compatible Zigbee hub (e.g., Samotech SM310ZHA Hub, deCONZ, SmartThings, Hubitat Elevation, Home Assistant) before proceeding.

4.2. Installation de la batterie
- Ouvrez délicatement le couvercle arrière du détecteur de mouvement.
- Insert the three AAA batteries into the battery compartment, ensuring correct polarity (+/-).
- Fermez bien le capot arrière.
4.3. Pairing with Your Zigbee Hub
Follow these general steps to pair your SM301Z sensor with your Zigbee hub. Specific steps may vary slightly depending on your hub's application:
- Assurez-vous que votre hub Zigbee est allumé et en mode d'appairage (reportez-vous au manuel de votre hub pour obtenir des instructions spécifiques).
- On the SM301Z sensor, locate the RESET button (usually a small pinhole button). Press and hold the RESET button for approximately 5 seconds until the LED indicator on the sensor begins to blink. This indicates the sensor is in pairing mode.
- Within your Zigbee hub's application, initiate the device search or 'add subdevice' function.
- The hub should discover the SM301Z sensor. Once detected, follow the on-screen prompts in your app to complete the pairing process.

4.4. Montage du capteur
The SM301Z sensor is designed for wall mounting. Choose a location where motion detection is desired, keeping in mind the 3-meter maximum range.
- Assurez-vous que la surface de montage est propre, sèche et lisse.
- Peel off the protective film from one side of the provided mounting adhesive.
- Attach the adhesive firmly to the back of the sensor.
- Peel off the remaining protective film from the adhesive and press the sensor firmly onto the desired wall location for at least 30 seconds.

5. Mode d'emploi
Once successfully paired and mounted, the SAMOTECH SM301Z motion sensor will detect movement within its 3-meter range and communicate this information to your Zigbee hub.
5.1. Détection de mouvement
The sensor uses Passive Infrared (PIR) technology to detect changes in infrared radiation caused by moving objects, such as people. When motion is detected, the sensor sends a signal to your Zigbee hub.

5.2. Creating Smart Routines
Leverage your Zigbee hub's capabilities to create automated routines based on motion detection:
- Automatisation de l'éclairage : Configure lights to turn on when motion is detected in a room and turn off after a set period of no motion.
- Alertes de sécurité : Receive notifications on your smartphone if motion is detected when you are away from home.
- Économie d'énergie : Automate devices to power down when no activity is detected.

6. Entretien
6.1. Remplacement de la batterie
The SM301Z sensor is designed for long battery life (3+ years). When the batteries are low, your Zigbee hub application may notify you. To replace the batteries:
- Ouvrez délicatement le couvercle arrière du détecteur de mouvement.
- Retirez les piles AAA usagées.
- Insert three new AAA batteries, ensuring correct polarity (+/-).
- Fermez bien le capot arrière.
- Jetez les piles usagées conformément à la réglementation locale.
7. Dépannage
If you encounter issues with your SAMOTECH SM301Z motion sensor, refer to the following common problems and solutions:
- Le capteur ne se connecte pas au hub :
- Assurez-vous que votre hub Zigbee est allumé et en mode appariement.
- Verify the sensor's batteries are correctly installed and charged.
- Perform a factory reset on the sensor by holding the RESET button for 5 seconds until the LED blinks, then attempt pairing again.
- Ensure the sensor is within range of your Zigbee hub during pairing.
- No motion detected or inconsistent detection:
- Check the sensor's placement. Ensure there are no obstructions blocking its field of view.
- Verify the batteries are not depleted.
- Confirm the sensor is still connected to your Zigbee hub in the app. If not, re-pair the device.
- Avoid placing the sensor near heat sources (e.g., vents, direct sunlight) as these can cause false detections.
- False motion detections:
- Review the sensor's placement to ensure it's not detecting pets, curtains moving in a draft, or reflections.
- Ensure the sensor is not exposed to direct sunlight or strong drafts.
