4  Introduction 

4.1  Purpose 

This chapter provides a general description of CMi4110. In the next-coming sections you will learn more 
about possible applications for the product and how CMi4110 can be combined

 

with other products to 

build versatile solutions. 

4.2  Application description 

CMi4110 is a cost-effective LoRaWAN meter connectivity module, which is mounted in a Gyr 
UH50 meter or a UC50 calculator. It uses a very energy-efficient scheme to deliver meter data to a 
receiving (application) server over a LoRaWAN network. Meter data is securely transmitted, using 
LoRaWAN end-to-end security scheme.  
  
CMi4110 can both be retrofitted into deployed meters or mounted before deployment. 

 

4.3  Product 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: 

 

 

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. Us

ing 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 mete

r’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.
