A Home Assistant blueprint for optimal and automated management of your air conditioner, focused on comfort and energy savings.

NOTE: This blueprint now supports multi-language notifications. It was mainly developed and tested with the Daikin Onecta integration (via HACS), but it may also work with other brands of air conditioners that have a Home Assistant supported climate entity. For any issues or suggestions, please do not hesitate to contact the author.

:dart: The “Comfort Temperature & Energy Saving” Principle

Enjoy a perfect climate at all times, knowing that your air conditioner automatically adapts to maximize comfort and energy efficiency.

This blueprint is based on a simple yet effective principle:

  • Prioritise Comfort: Maintains your ideal temperature.
  • Energy Efficiency: Detects when comfort is reached and switches to a low-power mode or turns the air conditioner off.
  • Adaptability: Automatically reactivates if the temperature rises again, ensuring continuous comfort.

:brain: How It Works

This blueprint combines constant ambient temperature monitoring with air conditioner control logic, creating a management system that:

  1. Activates the air conditioner in the desired mode when the temperature is out of range or at the start of the time window.
  2. Maintains comfort until the set target temperature is reached.
  3. Switches to “eco” mode (fan or off) once the target temperature is reached.
  4. Automatically reactivates if the ambient temperature rises above a defined threshold over the target.
  5. Allows for hourly scheduling for activation/deactivation of monitoring.
  6. Includes a dedicated master switch (an input_boolean) to quickly enable/disable the entire logic.

Main Scenarios

:sleeping: At the Start of the Time Window or High Temperature

  • At the start time (if configured) or upon activation of the automation/master switch (e.g., HA restart, master switch ON) and the temperature is already above the reactivation threshold → The air conditioner turns on in the Initial Climate Mode and sets the Target Temperature.
  • Notifications inform you of the activation.

:crescent_moon: During the Time Window and Ideal Temperature is Reached

  • Ambient temperature drops below the Target Temperature - Turn Off/Fan Offset → The air conditioner switches to Low Power Mode (e.g., fan_only or off).
  • This prevents frequent on/off cycles and reduces energy consumption.
  • Notifications inform you of the mode change.

:chart_with_upwards_trend: During the Time Window and Temperature Rises

  • Ambient temperature rises above the Target Temperature + Turn On Offset → The air conditioner reactivates in the Initial Climate Mode and sets the Target Temperature.
  • This ensures comfort is maintained without you having to intervene.
  • Notifications inform you of the reactivation.

:rocket: Prerequisites

Before importing and using this blueprint, make sure you have:

  • An ambient temperature sensor in your room.
  • A climate entity that controls your air conditioner.
  • ESSENTIAL: A Helper of type Toggle created in Home Assistant, which you will use as a master switch to enable/disable the automation. You can create it from: Settings :gear: > Devices & Services > Helpers > Create Helper > Toggle. Give it a recognizable name, e.g., Climate Master Switch.
Entity Status
Daikin Onecta :heavy_check_mark: (Tested)
Generic Climate :question: (May work)

:gear: Configuration Options

Parameter Description Type Required Default
master_enable The master switch. Select the input_boolean (the toggle helper) created in the prerequisites. It controls all the blueprint’s logic. entity (input_boolean) Yes
climate_entity The climate entity of your air conditioner. entity Yes
temperature_sensor The sensor that detects the room temperature (e.g., sensor.studio_room_temperature). entity Yes
target_temperature The desired temperature that the air conditioner should maintain. number Yes
turn_off_offset Degrees the temp. must DROP below the target before mode change (e.g., 1.0°C). number Yes 1.0
turn_on_offset Degrees the temp. must RISE above the target before reactivation (e.g., 1.5°C). number Yes 1.5
initial_climate_mode The operating mode when the air conditioner turns on (e.g., cool, heat_cool, heat). select Yes
low_power_mode The mode the air conditioner switches to when the target is reached (e.g., fan_only, off). select Yes
turn_off_timer_eco Timer in minutes to turn off the unit after entering low-power mode. Set to 0 to disable. number No 0
start_time The time at which management should start (e.g., 23:00). Leave blank for manual activation via the master switch. time No null
end_time The time at which management should end (e.g., 07:00). Leave blank for manual deactivation via the master switch. time No null
end_of_time_action Choose the action to perform at the end of the time window (e.g., turn off the climate, switch to fan mode). select No off
turn_off_timer_end Timer in minutes to turn off the unit at the end of the time window. Set to 0 to disable. number No 0
enable_notifications Enable or disable the sending of notifications. boolean No true
notification_service Service to send status messages to (e.g., notify.mobile_app_your_phone). text No notify.persistent_notification
language The language for notifications (it or en). select No en

:hammer_and_wrench: Installation & Configuration

  1. In Home Assistant, go to Settings > Automations & Scenes > Blueprints.

  2. Click on “Import Blueprint” in the top right corner.

  3. In the “Blueprint URL” field, paste the RAW link to your YAML file: https://raw.githubusercontent.com/tax987/ha-smart-management-hvac/v1.5.3/ha-smart-management-hvac.yaml.

  4. Click on “PREVIEW BLUEPRINT” and then on “IMPORT BLUEPRINT”.

  5. Once imported, click on “Create automation” next to the blueprint’s name.

  6. Carefully fill in all the fields, especially “Enable Management” by selecting the input_boolean Helper you created.

  7. Give your new automation a name and save it.

  8. Test the automation by turning the master switch on/off, simulating temperature changes, or forcing the times.

:shield: Handling Edge Cases

This automation has been designed to fluidly manage state changes:

  • Smart Activation: The air conditioner activates immediately at the start of the time window, on Home Assistant restart, or upon activation of the master switch if the temperature is already outside the comfort range.
  • Prevents continuous on/off cycling: Thanks to the configurable offsets, the air conditioner does not “cycle” continuously when the temperature approaches the target.
  • Home Assistant Restart: The logic restarts correctly after a system reboot, checking the current state and acting accordingly.
  • Time Flexibility: You can choose to have fully automated management based on times or control it manually via the master switch.
  • Master Control: The input_boolean master switch allows you to completely disable/enable the automation’s logic at any time, even if the times are configured, acting as a true kill switch.

:bulb: TIPS

This blueprint is perfect for use at night, for those who don’t want to wake up feeling cold or sore in the morning!

I’ve just used your blueprint to set up automations for AC units from Daikin and TCL. So far, they work great. Should make a real difference in the hot summer we’re about to have in my part of Australia.

Thanks a bunch!
