Spec score 8.4 #2 of 25 in Energy Management Software

What it is

FTW connects supported solar equipment, batteries, and car chargers from different brands for home energy use. Its Energyplan weighs charging needs, electricity prices and tariffs, solar and household forecasts, battery state, and efficiency to plan energy use. FTW Core checks proposed plans and commands against site and equipment limits, with a local fallback if the planner is unavailable. The beta indicates whether controlled devices are following FTW, waiting, limited, or need attention, using device readings and separate meter confirmation where available. Lua drivers connect supported meters, inverters, and batteries, although supported models, firmware, and verified functions vary. OCPP 1.6J and 2.0.1 chargers can connect to FTW's built-in server without a Lua driver, subject to their supported functions. FTW also lists API and Home Assistant connections for observation or automation. It runs on a user's own host, with Linux and Docker installation paths and Raspberry Pi or Linux deployment described. FTW is an early 0.x beta; active control requires a working site meter and confirmed main fuse rating.

Strong points and limits

Strong points

  • Plans account for tariffs, forecasts, and battery state
  • Local fallback if the planner is unavailable
  • OCPP 1.6J and 2.0.1 charger support
  • API and Home Assistant listed for observation or automation
  • Community edition is free and open source

Limits

  • Early 0.x beta release
  • Active control requires a working site meter
  • Main fuse rating must be confirmed
  • Supported device models and functions vary

Who it suits

FTW suits households seeking to coordinate supported solar, battery, and EV charging equipment on their own host. It is for users prepared to work with an early beta and confirm the required site meter and main fuse rating.

Verdict

FTW brings planning and local control together for supported home energy equipment. Its beta status, device compatibility variation, and meter and fuse prerequisites matter before relying on active control.
