A Home Assistant custom integration for weather-aware window ventilation and indoor-comfort recommendations.
VentWise helps users decide when opening or closing windows is likely to improve indoor comfort. It evaluates a standard weather source, optional outdoor temperature, humidity, and wind overrides, and the configured comfort target, then exposes a clear recommendation back to Home Assistant.
Warning
Beta software - use recommendations with care. VentWise has automated CI coverage and limited real-world use, but it has not been exhaustively tested across all homes, sensors, weather conditions, or hardware. It provides informational recommendations only; it is not a safety, security, weather- protection, or automation-control system. Optional room automations require an explicit Companion App notification confirmation. Always assess the actual conditions before opening or closing anything, and do not rely on VentWise to prevent injury, property damage, intrusion, rain exposure, or equipment damage. See the full license, disclaimer, and reporting guidance.
