Use an Echo Device + AC/Heat Controller to automate HVAC system

Step 1: Address Your Home’s Temperature Challenges

  1. Understand the Space:
    • Identify areas where temperature is uneven (e.g., kitchen/dining room vs. living room).
    • Note factors like partition walls, open spaces, or single-pane windows affecting air circulation and insulation.
  2. Enhance Airflow:
    • Use a powerful, oscillating fan like the Dreo 16-inch Smart Air Circulator to move warm air into cooler areas.
    • Place the fan on top of a partition wall or in a location where it can effectively distribute air.

Step 2: Enhance Temperature Monitoring

  1. Use a Smart Temperature Sensor:
    • Place an Amazon Echo Dot (4th or 5th Gen) or Echo Smart Air Quality Monitor in the cooler area to act as a temperature sensor.
  2. Positioning:
    • Ensure the Echo device is placed in a part of the room where you want better temperature control, away from direct heat sources or airflow.

Step 3: Upgrade Control with a Sensibo Device

  1. Install a Sensibo Controller:
    • Position the Sensibo AC/Heater Controller near the Mitsubishi unit, ensuring it has a clear line of sight to the unit for infrared communication.
  2. Connect to WiFi:
    • Use the Sensibo app to integrate the controller with your smartphone and link it to Amazon Alexa or Google Assistant.

Step 4: Create Smart Routines for Automated Control

  1. Set Up an Alexa Routine for Heating:
    • Open the Alexa app on your smartphone.
    • Go to Routines > Create Routine.
    • Name the routine (e.g., “Heat Control”).
    • Select When this happens > Smart Home > Choose your Echo device with a temperature sensor > Set a temperature threshold (e.g., below 68°F).
  2. Add an Action:
    • Select Device > Choose your Sensibo Controller > Set the action to turn on the heater.
  3. Create a Second Routine for Turning Off Heat:
    • Repeat the process, but set the temperature threshold to turn off the heater (e.g., above 72°F).

Step 5: Test the Setup

  1. Test the Fan:
    • Ensure the oscillating fan is distributing air to all areas.
    • Adjust the fan’s speed and oscillation using the app or voice commands with Alexa or Google Assistant.
  2. Test the Routines:
    • Observe how the system responds to temperature changes. Adjust thresholds as needed to achieve consistent comfort.

Step 6: Adjust for Summer Cooling

  1. Modify Alexa Routines for Cooling:
    • Set similar routines for summer to turn on cooling when the temperature exceeds a certain point and off when it drops.
  2. Fan Placement:
    • In summer, reposition the fan to optimize cool air distribution.

Optional Improvements

  1. Upgrade Insulation:
    • Consider insulating single-pane windows with thermal curtains or adding weatherstripping.
  2. Install a Secondary Unit:
    • If the fan isn’t sufficient, consider installing an additional mini-split unit in the dining area.

By following these steps, you can optimize your Mitsubishi mini-split system with smart controls to maintain a comfortable temperature throughout your home.
