Product overview


  • IoT-ready

    As soon as the meter connectivity module has been mounted and started up, it will automatically initiate transmission of meter data without any manual steps needed. The CMi6110 is prepared for seamless integration with all leading IoT platforms. It utilizes standards such as LWM2M, MQTT-SN and SenML-CBOR for fast and easy integration.

  • Battery or mains supply operated

    CMi6110 has several options for power supply. It can be battery operated for up to 10 years with daily transmission of meter data.

  • One-Touch Commissioning

    The product uses the Elvaco One-Touch Commissioning (OTC) to configure and deploy products quickly and securely. Using the Elvaco OTC App, simply enter your desired settings and place your mobile phone on the right side of the UH50 meter/UC50 calculator. New settings will be applied instantaneously via NFC.
