KPN Conditionsensor CO2 II

Last updated 2 months ago

Also known as Elsys ERS device. A Smart Building Sensor for indoor environment monitoring.

Supported network type(s): KPNLORA
Device Specification ID: kpn-conditionsensor-co2-ii
Device Specification UUID: 1dafa763-a81c-4452-a593-0517cd55e4d0

+ LoRa Geolocation data

Add LoRa Geolocation data to messages where location could be calculated.

› Decoded payload for environment monitoring

Decoder for v9 Elsys ERS payload.

Expected SenML records

› Decoded payload for environment monitoring (v2)

Decoder for Elsys ERS payloads. Fixes bugs in '› Decoded payload for environment monitoring':

distance was incorrectly converted to dm instead of m. Now the containing value is in meters.
soundAverage was decoded incorrectly, resulting in a number that is way too large.
soundPeak was decoded incorrectly, resulting in a number that is way too large.
The grideye fields were decoded incorrectly, where most results would be too big.
Time offsets were added as positive ts instead of negative ts.
acceleration values were processed as unsigned values, but they should have been processed as signed values.

This decoder also decodes Geolocation and Local Gateway data.

The following SenML records can be present, amongst others:

Example SenML

SenML can be structured in different ways, and we do not guarantee the examples below will look the same as what you will receive on your Destination. To make sure you can handle the SenML optimally, take a look at our documentation about Understanding and Interpreting SenML Data.
