The netdata sensor platform allows you to display information collected by Netdata.


A running Netdata instance, accessible from your Home Assistant instance. For more information on setting up Netdata, check out their documentation.


Getting the details to configure the sensors is a bit tricky as Netdata uses different name for the element: value that is required. To get the value for the data_group: use Netdata’s web interface. 1. marks the name for the data_group:. 2. are the names for the element to show in Home Assistant. The name that is shown can be different than the name under which the metrics are available.

To check if the element: name matches the name in the Netdata frontend, use curl with the IP address of your Netdata instance, its port and the data_group:

$ curl -X GET "http://[Netdata_Instance]:19999/api/v1/data?chart=[data_group]&points=2&options=jsonwrap"
   "api": 1,
   "id": "system.ipv4",
   "name": "system.ipv4",
   "dimension_names": ["received", "sent"],
   "dimension_ids": ["InOctets", "OutOctets"],
  • dimension_names: Names shown in the frontend.
  • dimension_ids: Names to use for element.

Alternatively you can browse to the built in Netdata API in your browser http://[Netdata_Instance]:19999/api/v1/allmetrics?format=json and search for the data_group identified in the Netdata frontend. In the example JSON below the data group is “system.load”.

	"system.load": {
		"last_updated": 1558446920,
		"dimensions": {
			"load1": {
				"name": "load1",
				"value": 0.1250000
			"load5": {
				"name": "load5",
				"value": 0.1290000
			"load15": {
				"name": "load15",
				"value": 0.1430000

Once the data_group “system.load” and the element “load15” have been identified from the JSON it can be configured in your configuration.yaml like the example below.


Add the following to your configuration.yaml.

# Example configuration.yaml entry
  - platform: netdata
        data_group: system.load
        element: load15
