I would like to share non-trivial AppDaemon app for optimizing energy usage and battery management to maximize self-consumption and minimize grid costs.
By integrating real-time solar production data, household consumption patterns, weather forecasts, and dynamic electricity pricing, the system makes autonomous decisions about when to store, consume, or discharge battery energy.
- Dynamically adjusts battery reserve SOC to prevent grid import during high-tariff periods
- Automatically determines the optimal hybrid inverter storage mode to maximize PV energy sales to the grid
- Calculates optimal battery discharge windows to maximize earnings from grid energy sales
Besides the features presented, you may also be interested in how I designed the application so that it is easy to write automated tests. That was very important to me because the optimization logic is quite complex, and verifying the algorithm’s behavior without tests would be very time-consuming. I believe that the ability to write automated tests is a huge advantage of AppDaemon compared to Home Assistant automation.
