Steps to reproduce:
In GUI, create an automation.
Trigger:
Time.
Specific time: 11:40:00 PM was selected.
Then Do:
Lock door. (Not that this matters). Clearly HA is now broken and doesn't know what time is.
Tried to manually edit the YAML and add in:
- id: 8c19ebea-17ef-4c90-878e-562ec644c107
alias: Automation School Mode Force - Automatically
initial_state: true
triggers:
- at: 23:40:00
trigger: time
conditions:
- condition: and
conditions:
- condition: time
weekday:
- mon
- tue
- wed
- thu
- fri
actions:
- action: lock.lock
continue_on_error: true
data: {}
target:
entity_id: lock.school_only
Same result. When you check the configuration, it's fine, but when you restart HA, it disabled the automation and gives the same error.
