Milesight EM300-TH: Switching On/Off

Preparation

Download the Milesight ToolBox app from the App Store or Play Store.

When using the app for the first time, you need to select the reading method. Choose NFC.

Complete the tutorial. Press the blue icon to scan your Milesight meter.

If you don’t know where the NFC sensor on your smart device is located, tap Can’t find the NFC location?
When you select Mobile, some devices will show you where the NFC sensor is located.

Attention!
On Android devices you must enable NFC in the settings.

Power On/Off with NFC

Scan the NFC sensor of the EM300-TH. It is located near the Milesight logo.

Turning the sensor on

Tap the toggle switch.

Scan the NFC sensor of the EM300-TH again.

Turning the sensor off

Tap the arrow behind Setting.

Tap the toggle switch next to Device Status.

Scan the NFC sensor of the EM300-TH again.

Power On/Off without NFC

If it’s not possible to turn on the Milesight via NFC, the sensor can also be switched on manually.

Remove the screws on the back of the sensor and open the device.
Press and hold the button for 3 seconds. The sensor will now change its status.

You can check the status of the sensor by briefly pressing the button.

• The LED lights up: the device is on.
• The LED does not light up: the device is off.

Warning!
If the LoRa base station is switched off while the Milesight EM300-TH is on, the sensor will continuously try to establish a connection. This will drain the battery more quickly.

All new sensors come preinstalled with fresh batteries. If a sensor goes offline shortly after activation, depleted batteries may be the cause.
The type of battery used is critical for proper operation. For this sensor, you should use ER18505 Li-SOCl2 lithium-batteries.
