1. An arrangement for sensor node calibration, comprising
a calibration chamber comprising or being connected to a controller configured to facilitate control of at least one calibration quantity or attribute in said calibration chamber,
a reference meter arranged to measure at least one calibration quantity or attribute inside the calibration chamber, and
a gateway device arranged to obtain from at least one sensor node
sensor node identifier (ID) information,
sensor node measurement information, wherein the gateway device is arranged to
identify a sensor node based on sensor node ID information received from the sensor node,
obtain measurement information from the identified sensor node,
obtain calibration quantity or attribute measurement in formation from the reference meter, and
compare said calibration quantity or attribute measurement information with said sensor node measurement information,
wherein the gateway device is further arranged to determine based on the comparison whether the calibration quantity or attribute measurement information and
the sensor node measurement information correlate, and
based on correlation, whether a sensor node measurement information measures the controlled calibration quantity or attribute in the calibration chamber.
