FTW vs Wia

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.

Wia is an energy intelligence platform for operators managing building portfolios. It combines meter, building-management-system, invoice and cloud data to monitor electricity, gas and water across sites. Data can arrive through retrofit IoT, cellular or LoRaWAN, BMS integration, manual uploads, invoice ingestion, cloud connections or an open API. Optimization tools rank savings opportunities, support solar-yield and charging optimization, and detect anomalies from actual consumption. Operations features include alerts, audits, surveys, tasks, device-health monitoring and remote firmware updates. Wia can schedule heating, cooling and lighting through BACnet or Modbus controllers and control VRF systems over their own protocol. Reports export as PDF, Excel or CSV for standards including CSRD, EPBD, EED, MEES, SECR and ISO 50001. ESG integrations include Watershed, Sweep, Persefoni, Plan A, Sphera, Greenstone and EcoVadis; REST, webhooks and OAuth are supported. Pricing is quoted per site after a remote survey. Wia supplies CSRD data but does not file regulatory returns.
