Is it hard to install for someone without much experience?

Is the gateway compatible with my Kamstrup meter?

The Kamst-IR Gateway is designed for use with all of Kamstrup’s energy and water meters. Simply mount the sensor on the Infra-Red eye of your meter and start monitoring your energy and water consumption.

My Kamstrup meter is equipped with a battery, does it run down quickly?

Most Kamstrup meters are powered via an internal battery. To conserve lifetime of the battery, the Kamst-IR gateway can be set to read the Kamstrup meter every hour. This can be done by adjusting the IR-Read interval on the gateway. This allows you to determine how often the measurement data is refreshed. At 15-minute intervals, an average battery lasts 10 years.
