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

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
fenêtres en comparant plusieurs capteurs de température extérieurs et intérieurs.

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)

Is this made with ki?

I ask because there are a lot of commits from Claude Code by Anthropic | AI Coding Agent, Terminal, IDE
This needs to be noted in the first post.
