 The same is true for the endpoints for sensors configured under `"dynamic"`.
 Currently only the sensors with the `value/unit/location/name/description` schema are implemented.
-At the time of writing this includes `temperature`, `barometer`, `humidity`, `beverage_supply`, `power_consumption`,
-and `account_balance`.
-Out-of-spec sensors may also be used as long as they share the same schema.

 ```shell
 curl -X PUT -u user:password -d 23.42 http://[::1]:8080/sensors/{temperature,humidity,...}[/location[/name]]
 ```
 
 As can be seen in the example, the http urls are generated from sensor type and optionally `location` and `name`.
-Depending on sensor type `location` might be required for your sensors, see the schema for details.
