Template Switch¶
The template switch platform allows you to create simple switches out of just actions and
an optional value lambda. Once defined, it will automatically appear in Home Assistant
as a switch and can be controlled through the frontend.
# Example configuration entry
switch:
- platform: template
name: "Template Switch"
lambda: |-
if (id(some_binary_sensor).state) {
return true;
} else {
return false;
}
turn_on_action:
- switch.turn_on: switch2
turn_off_action:
- switch.turn_on: switch1
optimistic: true
Possible return values for the optional lambda:
return true;if the switch should be reported as ON.return false;if the switch should be reported as OFF.return {};if the last state should be repeated.
Configuration variables:¶
- name (Required, string): The name of the switch.
- lambda (Optional, lambda): Lambda to be evaluated repeatedly to get the current state of the switch. Only state changes will be published to MQTT.
- optimistic (Optional, boolean): Whether to operate in optimistic mode - when in this mode,
any command sent to the template cover will immediately update the reported state and no lambda
needs to be used. Defaults to
false. - turn_on_action (Optional, Action): The action that should be performed when the remote (like Home Assistant’s frontend) requests the switch to be turned on.
- turn_off_action (Optional, Action): The action that should be performed when the remote (like Home Assistant’s frontend) requests the switch to be turned off.
- restore_state (Optional, boolean): Sets whether esphomelib should attempt to restore the
state on boot-up and call the turn on/off actions with the recovered values. Defaults to
yes. - id (Optional, ID): Manually specify the ID used for code generation.
- All other options from Switch and MQTT Component.
