Hi, normally my persistance and googling would have sorted this out by now but for the life of me I just can’t seem to crack it and it appears so simple. Basically I have a button that when pressed, I want to execute a script based on the state of a switch. So if the switch is off, run the script that turns it on (and then off after 30 mins). If the switch is on, then turn it off. Just can’t see where I’m going wrong. The error I keep getting is:
Failed to call service script/turn_on. sequence item 0: expected str instance, Optional found
Here is my code:
type: 'custom:button-card'
entity: switch.bathroom_relay_switch_2
icon: 'mdi:fan-off'
name: Bathroom Fan
tap_action:
action: call-service
service: script.turn_on
data_template:
entity_id: |
{% if is_state('switch.bathroom_relay_switch_2', 'off') %}
script.run_bathroom_fan_for_30_mins
{% else %}
script.turnoff_bathroom_fan
{% endif %}
show_state: true
state:
- value: 'on'
