Globals

Global variables store a single value that actions can update at runtime with globals.set. globals is built into UbiHome.

globals:
  - id: door_open
    type: bool
    initial_value: false

Attributes

Property	Description	Example
id	Identifier used to reference the global.	door_open
type	Value type: bool, int, float or string.	bool
initial_value	Value the global starts with. Defaults per type.	false

initial_value and globals.set accept the value as a plain YAML scalar matching type (e.g. an unquoted false or 42) or as a quoted string (e.g. 'false') — both are reconciled against the global’s declared type.

Globals are written via the globals.set action, which takes id/value arguments instead of a single id:

- globals.set:
    id: door_open
    value: true

A bool global can also be read as the state of a template switch using a globals.get lambda — written in YAML, not code:

switch:
  - platform: template
    name: 'Relay'
    lambda:
      globals.get: door_open
