# Mounting guidelines

Proper installation ensures reliable Bluetooth communication and accurate measurements. Verify that the chosen location follows the [installation best practices](/efento-ble-loggers/installation/installation-best-practices.md).

{% hint style="warning" %}
Before mounting any logger, **make sure it is powered on** and visible to a smartphone or gateway.

### **Mounting steps**

1. Clean the surface where the logger will be placed (dry, smooth, and dust-free).
2. Peel off the protective film covering the 3M adhesive pad on the back of the logger.
3. Press the logger firmly against the surface for several seconds.
4. Avoid touching or repositioning the logger for a few minutes to ensure proper adhesion.

{% hint style="info" %}
Adhesive mounting is ideal for walls, doors, racks, and other flat indoor surfaces.

## **Mounting IP67** loggers

Efento loggers in IP67 enclosures are designed for harsh or outdoor environments and require more secure mounting.

### **Mounting options**

* **Screws** – use mounting holes in the enclosure to fix the device to walls, equipment, or structural surfaces.
* **Cable ties** – suitable for poles, frames, or places where drilling is not possible.

### **Mounting steps**

#### **Using screws**

Use the screws included in the set, as they are corrosion-resistant. If using alternative screws, make sure they are also corrosion-resistant.

1. Position the logger on the wall and mark the locations for drilling.
2. Drill holes using a 5 mm drill bit.
3. Remove dust from the holes and insert wall plugs.
4. Mount the logger using the screws, ensuring it is firmly secured.

#### **Using cable ties**

1. Choose cable ties of appropriate length and strength for the mounting location. The cable tie used should not exceed a width of 10 mm.
2. Thread the cable ties through the logger's mounting slots and tighten them firmly so the logger does not move or vibrate during operation.
