The product is easily configured through Elvaco OTC mobile app or via DM-system, has several different message formats and is ideal for applications where long range is required. The CMi6140 can be battery operated for up to 10 years. Meter data delivery and device management utilizes standard protocols, such as MQTT-SN and LWM2M for easy integration to existing systems.
