Template Number

The template number platform allows you to create a number with templated values using lambdas.

# Example configuration entry
number:
  - platform: template
    name: "Template number"
    optimistic: true
    min_value: 0
    max_value: 100
    step: 1

Configuration variables

• min_value (Required, float): The minimum value this number can be.

• max_value (Required, float): The maximum value this number can be.

• step (Required, float): The granularity with which the number can be set.

• lambda (Optional, lambda): Lambda to be evaluated every update interval to get the current value of the number.

• set_action (Optional, Action): The action that should be performed when the remote (like Home Assistant’s frontend) requests to set the number value. The new value is available to lambdas in the x variable.

• update_interval (Optional, Time): The interval on which to update the number by executing the lambda. Defaults to 60s.

• optimistic (Optional, boolean): Whether to operate in optimistic mode - when in this mode, any command sent to the template number will immediately update the reported state. Cannot be used with lambda. Defaults to false.

• restore_value (Optional, boolean): Saves and loads the state to RTC/Flash. Cannot be used with lambda. Defaults to false.

• initial_value (Optional, float): The value to set the state to on setup if not restored with restore_value. Cannot be used with lambda. Defaults to min_value.

• All other options from Number.

number.set Action

You can also set the number for the template number from elsewhere in your YAML file with the number.set Action.
