đŸȘŸ Heatwave Windows / FenĂȘtres Canicule — Open or close windows based on multi-sensor temperature comparison

Blueprints Exchange

During a heatwave, this blueprint notifies you when to open or close your windows
by comparing multiple outdoor and indoor temperature sensors.

:france: Pendant une canicule, ce blueprint vous notifie quand ouvrir ou fermer vos
fenĂȘtres en comparant plusieurs capteurs de tempĂ©rature extĂ©rieurs et intĂ©rieurs.

Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.

Logic:

  • Open :window: : max(outdoor) < min(indoor) → cooler outside than inside
  • Close :window: : max(outdoor) > min(indoor) → warmer outside than inside

Requirements: Temperature sensors (device_class: temperature) indoors and outdoors + HA Companion App

Languages: :france: French / :united_kingdom: English — more languages welcome via PR on GitHub!

I don’t have an outside temperature sensor, but the forecast default entity could be a useful option for the external temperature <3 (edit: further poking had me add a nearby weather station from Ambient Weather so yay. next mission for me is to figure out PM2.5 data to know when to close windows to prevent suffering during wildfire season)
