Create new service which allows the boosting of hotwater in a similar way to boosting heating ( service wiser.boost_heating)

This is what I use for calling the script in a lovelace button.

Press and hold returns the hot water setting to auto:

type: button
tap_action:
  action: call-service
  service: script.boost_hot_water_for_one_hour
  service_data: {}
  target: {}
entity: sensor.wiser_hot_water
name: Boost Hot Water
show_state: false
hold_action:
  action: call-service
  service: wiser.set_hotwater_mode
  service_data:
    hotwater_mode: auto
  target: {}
