NotiFreeze 🥶 🥵

python_badge hacs_badge

News ✌️ NotiFreeze v0.5.0 contains new features and breaking changes! 🥶 Check below for more info about new config format!


NotiFreeze is an AppDaemon app which reminds to close windows if temperature difference between inside/outside exceeds a specified threshold.*

This works for every room separately e.g. an open window in the bathroom checks outside temperate against the bathroom temperature sensor. Useful in winter to remind you to close the bathroom windows after airing 🥶 but also in the summer when you do not want that hot outside air inside 🥵

Note: In NotiFreeze you configure just one App for all your rooms in contrast to separate apps/configurations per room like in AutoMoLi.

Installation

Use HACS or download the notifreeze directory from inside the apps directory here to your local apps directory, then add the configuration to enable the notifreeze module.

Auto-Discovery of Entities/Sensors

If sensors entities have an entity id matching:

  • binary_sensor.door_window_*
    or
  • sensor.temperature_*

and

  • an entity id or friendly name containing the room/room name

NotiFreeze will detect them automatically. (Manually configured entities will take precedence.)

Configuration Example

notifreeze:
  module: notifreeze
  class: NotiFreeze
  locale: de_DE
  notify_service: notify.mobile_app_ben
  always_notify: true
  outdoor: sensor.temperature_outdoor
  max_difference: 4.2
  delays:
    initial: 3
    reminder: 7
  rooms:
    - Schlafzimmer
    - Bad
    - name: Wohnzimmer
      alias: livingroom  # entity ids contain *livingroom* but not *wohnzimmer*
    - name: Keller
      door_window: binary_sensor.door_window_sensor_basement_window
      indoor:
        - sensor.temperature_basement
        - sensor.temperature_basement_front
