Hi,
Looking to trigger an automation at quarter past and quarter to (not on the hour). I’ve tried various combos but am stuck, any ideas?

description: “Check solar to start Heat Pump”
trigger:
- trigger: time_pattern
minutes: 15, 45
condition:

Use two triggers

triggers:
  - trigger: time_pattern
    minutes: 15
  - trigger: time_pattern
    minutes: 45

or use / to trigger on all minute values divisible by 15, as shown and described in the docs. Then use a template condition to require it to be 15 or 45:

triggers:
  - trigger: time_pattern
    minutes: /15
conditions:
  - condition: template
    value_template: "{{ now().minute in [15, 45] }}"

Perfect, thank you.
