 You need to configure the following environment variables:
 
 - `KNX_GATEWAY_IP` is the address of the gateway/router. Default value is *10.0.0.36*
-- `KNX_TOPOLOGY` is the CSV export of the group adresses. It's used to map the monitored data with types and store the proper values. It defaults to *export-addresses.csv*. PLease see below how to export the right format.
+- `KNX_TOPOLOGY` is the CSV export of the group adresses. It's used to map the monitored data with types and store the proper values. It defaults to *export-addresses.csv*. Please see below how to export the right format.
+
+- `LOG_ONLY` only logs the collected information, doesn't push to InfluxDB. It defaults to *1*
 
 - `INFLUX_BUCKET` - the bucket to store the data. It defaults to *my_bucket*
 - `INFLUX_ORG` - the organisation (defined when you initialise the bucket). Defaults to *example.com*
