Energy Arbitrage: Automating Savings with Tibber and EVCC

With the current high energy prices in Germany, I decided to take matters into my own hands and optimize my energy consumption. I’ve built a system that automatically charges my house battery during cheap grid hours and discharges it during peak times, saving me around €2-3 per day in winter. It’s a fun and practical way to make the most of my energy usage!

Here’s how it works: I use Tibber’s integration to track real-time energy prices. My system identifies periods when prices are below a certain threshold (configured as €0.08) and charges the battery during those times. When prices rise above 50% of the daily spread, the battery starts discharging to power my home. This setup ensures I’m always using energy when it’s cheapest.

I’ve set up a few automation rules to manage this process. The first rule monitors price changes and adjusts the battery’s charging limit based on the current price. The second rule controls discharging, ensuring it only happens when prices are high enough to justify the energy loss during charging and discharging cycles.

The best part? This system is entirely automated, so I don’t have to lift a finger. It’s been running smoothly for months, and I’ve already noticed a significant reduction in my energy bills. If you’re looking for ways to save on energy costs, I’d highly recommend exploring similar automation strategies!

Who knew optimizing energy usage could be so rewarding? :blush:
