FTW
Kalmar, Sweden
What it is
FTW is an open-source home energy system that connects supported solar equipment, batteries, and car chargers from different brands. Its Energyplan considers charging needs, electricity prices, tariffs, solar and household forecasts, battery state, and efficiency when planning energy use. FTW Core checks proposed plans and commands against site and equipment limits and keeps a local fallback if the planner is unavailable. The beta indicates whether devices are following FTW, waiting, limited, or need attention, using device readings and, when available, separate meter confirmation. Lua drivers connect supported meters, inverters, and batteries, while OCPP 1.6J and 2.0.1 chargers can use the built-in server subject to supported functions. API and Home Assistant connections are listed for observation or automation. FTW runs on a user’s Raspberry Pi or Linux host, with Linux and Docker installation paths. Active control requires a working site meter and confirmed main fuse rating.
For and against
For
- Open-source community edition
- Plans energy using prices, forecasts, and battery state
- Local fallback when planner is unavailable
- Supports OCPP 1.6J and 2.0.1 chargers
- API and Home Assistant listed
Against
- Current release is an early 0.x beta
- Guided migration of old settings is unavailable
- Active control requires a working site meter
- Community support has no warranty or SLA
The verdict
FTW offers local, open-source coordination across supported home-energy devices with forecasting and automation interfaces. Its beta status, hardware requirements, varying device support, and licensing conditions require attention before deployment.
Who it suits
FTW suits private households that want local coordination of solar, batteries, and EV charging. It is intended for users comfortable running beta software on their own host.
