CMi4110

CMi4110

The CMi4110 is a Meter Connectivity Module (MCM) that is integrated into LoRaWAN networks to forward meter data to the receiving server. The meter module can either be installed directly from the factory in an L+G UH50/UC50 or retrofitted to the meter later. Last but not least, the CMi4110 is characterized by a long battery life of at least eleven years, low acquisition and operating costs and a long communication range of up to 25 km. This makes the meter module a powerful and reliable building block in the Internet of Things (IoT).

CMi4110 - Integrated MCM for Landis + Gyr UH50/UC50, LoRaWAN

The rapid growth of IoT (“Internet of things”) has resulted in new communication techniques, specifically developed to meet the growing demand of high energy-efficiency and long range. LoRaWAN is one such technique. CMi4110 is mounted inside a L+G UH50/UC50 to deliver meter data to a receving server via a LoRaWAN network. The product is energy-efficient (battery-life of at least 11 years), has a long communication range (up to 25 km) and is easily retrofitted inside an already-deployed meter. With CMi4110, Elvaco offers an MCM designed for customers that require a cost-effective solution with lesser demand for bandwidth.

An easy-to-understand user interface shows what status the CMi4110 is currently in. Self-explanatory are the green or red LEDs, which indicate perfect operation or an error. While a push button is used to switch on the meter module, the configuration is done via NFC and the Elvaco OTC app or via a LoRaWAN radio connection through a downlink. 

Available in two versions with an internal or an external antenna with magnet or for wall mounting, the CMi4110 can be optimally adapted to the requirements of your metering infrastructure.

Transmissions

As a Meter Connectivity Module (MCM), the CMi4110 combines a long communication range of up to 25 km with high energy efficiency and cost-effective operation. The meter module collects and structures the data determined by heat meters in order to compile them into radio telegrams and deliver them to the receiving system on the basis of a LoRaWAN network. In this way, the CMi4110 becomes an essential part of modern IoT systems. 

A major advantage of the CMi4110 is its ease of retrofitting, which means that it can also be easily connected to already installed meters. Alternatively, the meter module can also be mounted before the meter is commissioned. 

An important advantage of the CMi4110 is the long battery life of at least 11 years, which guarantees long and reliable operation as well as high energy efficiency. The combination of a high communication range and economical operation with low broadband requirements also speak in favour of using the CMi4110 in your metering processes. Last but not least, the meter module can be easily integrated into any LoRaWAN network management, as it transmits the telegrams in the LoRaWAN payload using standardized M-Bus coding.
