Emoncms Sensor

The emoncms sensor platform creates sensors for the feeds available in your local or cloud based version of Emoncms.

To enable this sensor, add the following lines to your configuration.yaml, it will list all feeds as a sensor:

# Example configuration.yaml entry using cloud based Emoncms
sensor:
  platform: emoncms
  api_key: API_KEY
  url: https://emoncms.org
  id: 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 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”.

Default naming scheme

The names of the sensors created by this component, will be a combination of static text, id from the config and feedid from the Emoncms feed, unless sensor_names is used. An example name would be emoncms1_feedid_10.

Examples

In this section you find some more examples of how this sensor can be used.

Display only feeds with their feed IDs specified in include_only_feed_id.

# Example configuration.yaml entry
sensor:
  - platform: emoncms
    api_key: API_KEY
    url: https://emoncms.org
    id: 1
    unit_of_measurement: "W"
    include_only_feed_id:
      - 107
      - 105

Display all feeds except feeds with their feed id specified in exclude_feed_id.

# Example configuration.yaml entry
sensor:
  - platform: emoncms
    api_key: API_KEY
    url: https://emoncms.org
    id: 1
    unit_of_measurement: "KWH" 
    exclude_feed_id:
      - 107
      - 105

Display only feeds with their feed id’s specified in include_only_feed_id and give the feed sensors a name using “sensor_names”. You don’t have to specify all feeds names in “sensor_names”, the remaining sensor names will be chosen based on “id” and the Emoncms feedid.

# Example configuration.yaml entry
sensor:
  - platform: emoncms
    api_key: API_KEY
    url: https://emoncms.org
    id: 1
    unit_of_measurement: "KW" 
    include_only_feed_id:
      - 5
      - 120
    sensor_names:
      5: "feed 1"
      48: "kwh feed"
      61: "amp feed"
      110: "watt feed"

Use a value_template to add 1500 to the feed value for all specified feed IDs in include_feed_id.

# Example configuration.yaml entry
sensor:
  - platform: emoncms
    api_key: API_KEY
    url: https://emoncms.org
    scan_interval: 15
    id: 1
    value_template: "{{ value | float + 1500 }}"
    include_only_feed_id:
      - 107
      - 106

Display feeds from the same Emoncms instance with 2 groups of feeds, different scan_interval and a different unit_of_measurement.

# Example configuration.yaml entry
sensor:
  - platform: emoncms
    api_key: API_KEY
    url: https://emoncms.org
    scan_interval: 30
    id: 1
    unit_of_measurement: "W" 
    include_only_feed_id:
      - 107
      - 106
  - platform: emoncms
    api_key:  put your emoncms read api key here
    url: https://emoncms.org
    id: 2
    scan_interval: 60
    unit_of_measurement: "A" 
    include_only_feed_id:
      - 108
      - 61
