Base sensors filters¶

Some sensors allows to specify filters which allows transformation of value before sending it to MQTT.

Currently available sensors to filter values are:

Filters are always list of dictionary, where key is name of operation and value is value to use in operation eg

filters:
  - round: 2

means that filter will round sensor value to 2 decimal places.

Configuration variables:¶

Available filters¶

offset¶

Adds a constant value to each sensor value.

- platform: dallas
  ...
  filters:
    - offset: 5

round¶

Round sensor value to X digits after .

- platform: dallas
  ...
  filters:
    - round: 2

multiply¶

Multply sensor value by constant value.

- platform: dallas
  ...
  filters:
    - multiply: 1.5

filter_out¶

Filter out value if it is equal to constant value

- platform: dallas
  ...
  filters:
    - filter_out: 17

filter_out_greater¶

Filter out value if it is greater than constant value

- platform: dallas
  ...
  filters:
    - filter_out_greater: 17

filter_out_lower¶

Filter out value if it is lower than constant value

- platform: dallas
  ...
  filters:
    - filter_out_lower: 17
