# Welcome to Hungry Machines Docs

One optimizer, four ways to connect it — Home Assistant, Home Hub, Smart Satellite, or your own client on the API.

Outsmart your electric bill - Hungry Machines Energy provides an energy management system that shifts HVAC, EV charging, home batteries, and other electric loads to cheaper hours for homes and buildings with solar power or variable electricity rates. Every route runs the same optimizer; the difference is what carries out the plan.
- [Home Assistant](/home-assistant/): Add it to the Home Assistant you run — a HACS package, no new hardware. Shipping today.
- [Home Hub](/home-hub/): A pre-built appliance that runs your HVAC, water heater, EV charger and battery together, no Home Assistant needed. Beta list.
- [Smart Satellite](/satellite/): A WiFi device for one window AC or mini-split — no thermostat, no hub. Beta list.
- [Build on the API](/for-developers/): Create your own frontend, Home Assistant integration, or device client. Public API contract with worked examples. Shipping today.
