SlimLaden creates a dynamic charging plan for your home battery. The app pairs cheap charging quarters with expensive discharging quarters, maximizing profit from price differences. Pairs are only scheduled when the price difference is sufficient (after accounting for battery losses).
Configuration and diagnostics at: http://[Homey IP address]:8778/diagnostics.html
The plan combines dynamic energy prices, solar forecasts, and consumption patterns. Consumption forecasting automatically adapts to your actual usage via Homey Energy and accounts for degree days. Marstek and Sessy (beta) batteries are controlled directly, other brands can use the plan via flows.
Triggered after adaptive learning updates and blends usage fractions.
