Features

CMi4110 has the capability to offer a combination of battery operation with very long lifetime and a versatile application through its many configuration options.

Key features of the module include:

  • LoRaWAN certified

    The CMi4110 is certified according to LoRaWAN alliance.

    See https://lora-alliance.org/lora_products/cmi4110ext/ for more information.

  • Long battery lifetime

    The module’s EcoMode feature enables the module to achieve a battery-lifetime of at least 11+1 years.

  • No meter installation needed

    As soon as the meter connectivity module has been mounted and started up, it will join the LoRaWAN network and start delivering meter data, i.e. no manual steps need to be taken in order to install the product in the meter.

  • Quick commissioning

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

  • A unique and flexible message scheme

    • Meter data aligned with meter’s internal clock and redundant daily energy values enables coordinated high-precision readouts without network congestion and assures reliable delivery of daily energy consumption.

    • Several message formats to choose between, including JSON, gives the right fit for the unique demands of each application.

Compatibility

CMi4110 is compatible with all L+G UH50 meter and L+G UC50 calculators with a compatible firmware version. Once the module is mounted and starts up, a compatibility check is made to ensure that it is compatible with the meter firmware. If the module is mounted in an incompatible meter, this is indicated in the OTC App.

CMi4110 is supplied with power from the UH50/UC50 D cell battery. The module is also compatible with Elvaco’s 230V CMip2110 PSUs and with the following PSUs from Landis+Gyr: WZU-AC230, WZU-AC110, WZU-ACDC24-00.
