MELCloud Optimizer for Homey - Now Available!

I’m excited to announce the release of MELCloud Optimizer, a new app that connects your Mitsubishi Electric heat pump with Homey to optimize its operation based on real-time electricity prices and weather conditions.

What It Does

MELCloud Optimizer automatically adjusts your heat pump’s target temperature based on electricity prices from Tibber, helping you save money while maintaining comfort. The app features:

  • Smart Price Optimization: Increases temperature during cheap hours and decreases during expensive hours
  • Advanced Thermal Learning: Uses a data-driven model that adapts to your home’s specific characteristics
  • Weather Integration: Incorporates weather data to adjust temperature based on outdoor conditions
  • Comfort Profiles: Adjusts temperature based on time of day and sleep patterns
  • Hot Water Tank Control: Optimizes hot water tank temperature based on electricity prices

How It Works

The app runs on two main schedules:

  1. Hourly Optimization: Every hour, the app fetches current electricity prices, weather data, and indoor/outdoor temperatures to calculate the optimal target temperature.
  2. Weekly Calibration: The app analyzes the past week’s data to refine its thermal model, making it more accurate over time.

Requirements

  • Homey Pro (SDK 3.0 compatible)
  • Mitsubishi Electric heat pump connected to MELCloud
  • MELCloud account credentials
  • Tibber account with API token

Installation

  1. Install from the Homey App Store
  2. Configure your MELCloud and Tibber credentials
  3. Set your preferred temperature range and comfort settings

All data is stored locally on your Homey, and credentials are only used for API calls to the respective services.

I’d love to hear your feedback and suggestions for future improvements!
