+As of Feb 2020, the integration will discover all sensors from Emoncms and will use the unit of measurement specified in the Feed from Emoncms, in preference to the one set in the configuration. Tested with [Emoncms](https://github.com/emoncms/emoncms) V10.1.13 - `unit` was added to the API around version V9.9.1.

 ## Configuration variables
 
-- `api_key` (*Required*): The read API key for your Emoncms user.
-- `url` (*Required*): The base URL of Emoncms, use <https://emoncms.org> for the cloud based version.
-- `id` (*Required*): Positive integer identifier for the sensor. Must be unique if you specify multiple Emoncms sensors.
-- `include_only_feed_id` (*Optional*): Positive integer list of Emoncms feed IDs. Only the feeds with feed IDs specified here will be displayed. Can not be specified if `exclude_feed_id` is specified.
-- `exclude_feed_id` (*Optional*): Positive integer list of Emoncms feed IDs. All the feeds will be displayed as sensors except the ones listed here. Can not be specified if `include_only_feed_id` is specified.
-- `sensor_names` (*Optional*): Dictionary of names for the sensors created that are created based on feed ID. The dictionary consists of `feedid: name` pairs. Sensors for feeds with their feed ID mentioned here will get the chosen name instead of the default name
-- `value_template` (*Optional*): Defines a [template](/docs/configuration/templating/#processing-incoming-data) to alter the feed value.
-- `scan_interval` (*Optional*): Defines the update interval of the sensor in seconds.
-- `unit_of_measurement` (*Optional*): Defines the unit of measurement of for all the sensors. default is "W".
