by a long green blink.
Caution: Using batteries other than
the ones provided may result in loss of
performance, battery life, and also damage
to the device.
3. Mount the back panel securely to the
wall with at least 2 appropriate screws,
using some of the four mounting holes.
Alternatively, attach the sensor with double
sided adhesive tape.

4. Use the application to change any settings if needed.
5. Hold the smartphone on top of the NFC antenna
placement to transfer the new settings to the sensor.
6. Wait for the sensor to reboot (1 sec), indicated by the blue
LED flashing. Sensor settings have now been updated.
To read data
The rst scanning will wake up the sensor and collect current
meter value.
4. Within 30 sec, press on “SCAN” again and hold the
smartphone on top of the sensor’s NFC antenna.
The second scanning will show the current meter value.
TROUBLESHOOTING
The master does not receive any telegram from the sensor
Please verify that:
• The batteries are correctly installed.
• The master is connected to a power source and is correctly congured.
• The master is within range of the radio singal.
• The master antenna is properly mounted for ideal performance.
• The master and the sensor use the same wireless M-Bus mode (default C1).
• The sensor is not mounted inside a metallic cabinet.
• The sensor is not disturbed by other radio equipment.
• The sensor battery voltage is in operating condition, use Elvaco OTC App
(NFC) to verify.
• If the meter value does not show up in the OTC app after a second scanning
the sensor is not powered.
Temperature value is inaccurate

positioning of the product can sometimes result in unintended temperature
variations. When mounting the sensor, please verify that:
• The product is not mounted near any heat or cold sources.
• The product is not mounted in direct sunlight.
• The product is not mounted in a spotlight beam.
