Home Assistant is excellent and endlessly flexible. With enough time you can build price-based charging, battery control and more using community integrations — and it’s free software.
FYXO is the managed alternative: it’s purpose-built for energy-cost optimisation, connects in minutes, adds a safety layer that validates every action, and is maintained and supported for you. It also integrates with Home Assistant if you want the best of both.
