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: 1Configuration 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 - xvariable.
- 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.

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