Emoncms	Instructions on how to integrate Emoncms feeds as sensors into Home Assistant.	Sensor	0.29	Local Polling	emoncms	@borpin	sensor	integration

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

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 V10.1.13 - unit was added to the API around version V9.9.1.

Configuration variables

{% configuration %} api_key: description: The read API key for your Emoncms user. required: true type: string url: description: "The base URL of Emoncms, use https://emoncms.org for the cloud-based version. For self-hosted Emoncms or EmonPi you may need a URL of http://x.x.x.x/emoncms." required: true type: string id: description: Positive integer identifier for the sensor. Must be unique if you specify multiple Emoncms sensors. required: true type: integer include_only_feed_id: description: 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. required: false type: list exclude_feed_id: description: 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. required: false type: list sensor_names: description: "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." required: false type: [integer, list] value_template: description: Defines a template to alter the feed value. required: false type: template scan_interval: description: Defines the update interval of the sensor in seconds. required: false type: integer unit_of_measurement: description: Defines the unit of measurement to be used for any sensor where the unit is not set in Emoncms. If no unit is set in Emoncms or in the configuration, the default (W) will be used. required: false default: W type: string {% endconfiguration %}

Default naming scheme

The names of the sensors created by this integration will use the feed names defined in Emoncms if available, or the feed ID otherwise, and will be prefixed with "Emoncms", e.g., "Emoncms Total Power" or "Emoncms Feed 5". If the id property is anything but 1, the ID will be shown as well, e.g., "Emoncms 2 Feed 5".

If sensor_names is used, any feeds with defined names will get those names exactly, with no prefix.

Examples

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

Minimal configuration. All Feeds are added as sensors with the unit of measurement being set by the Emoncms Feed or the default unit.

sensor:
  - platform: emoncms
    api_key: API_KEY
    url: https://emoncms.org
    id: 1

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.

{% raw %}

# 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

{% endraw %}

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:  API_KEY
    url: https://emoncms.org
    id: 2
    scan_interval: 60
    unit_of_measurement: "A"
    include_only_feed_id:
      - 108
      - 61
