    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 is activated, it will join the LoRaWAN® network and start to deliver meter data, i.e. no manual steps need to be taken in order to install the product in the meter.

  • Quick commissioning

    With Elvaco’s One-Touch Commissioning (OTC), deployment, configuration and key transferring can be performed in a secure and flexible way. Use the Elvaco OTC App to enter your desired settings and place your phone next to the meter. New settings will be applied via NFC.

  • A unique and flexible message scheme

    CMi4111 has several different message formats to choose from. This makes it easy to customize the product to the unique demands of each application.


CMi4111 is compatible with L+G T230 and L+G T330 heat/cooling meters 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.

The following table shows the minimum firmware versions required.
