CMi4170

The CMi4170 is a meter communication module, which is installed in the heat meters Sensostar/Sensostar C from Engelmann and is used to transmit the meter data to the receiving server. As an internal Meter Connectivity Module (MCM), the CMi4170 is based on the LoRaWAN network, which is used to send the meter data combined into telegrams. A long battery life, first-class energy efficiency and an excellent communication range characterize the MCM for the Engelmann Sensostar heat meter.

CMi4170 - Integrated LoRaWAN MCM for Engelmann Sensostar heat meters

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. CMi4170 is mounted inside an Engelmann Sensostar/Sensostar C to deliver meter data to a receiving server via a LoRaWAN network. The product can achieve up to 10+1 years of battery life, is energy-efficient, has a long communication range and is easily retrofitted inside an already deployed meter. CMi4170 is easily configured through Elvaco OTC mobile app (via NFC). With CMi4170, Elvaco offers a meter communication module designed for customers that require a user-friendly and cost-effective solution.

In just a few simple steps, the CMi4170 can be mounted in the Engelmann Sensostar/Sensostar C heat meters with little expertise and then put into operation. An easy-to-understand user manual helps with activation and NFC configuration via the Elvaco OTC app. The CMi4170 has two colored status LEDs as well as a push button for switching on, off and rebooting the meter module.

 

The individual setting of the transmission interval in which the meter module communicates with the server also influences the battery life of the CMi4170. In order to achieve the maximum battery life of eleven years, the energy-efficient EcoMode can be used. Another practical feature of the CMi4170 is the configuration lock, which prevents unauthorized access to the meter module and can only be managed by authorized persons via the Elvaco OTC app.

Elvaco CMi 4170 is an established Meter Connectivity Module (MCM) for transmitting meter data from Engelmann Sensostar heat meters over a LoRaWAN network to the receiving server. The internal meter communication module is mounted directly in the heat meter, wired to the meter via a special interface and integrated into the LoRaWAN network. The configuration works in a simple way via the associated OTC app from Elvaco. For this purpose, NFC technology is used, which enables a simple way of activation and configuration in a few simple steps.

 

The user interface of the CMi4170 consists of two colored status LEDs and a multifunctional pushbutton. Thanks to the long battery life, which can be significantly extended by using the practical EcoMode, and the long communication range, the meter module is particularly energy-efficient and extremely reliable.
