I have 3 lamps that I want to automate together. A and B are smaller lights and C is a larger light.
If A or B is turned on, C must turn on. If A or B is turned off, C must turn off. The other light (B or A) must not be affected.
If C is turned on, A and B must both turn on. If C is turned off, A and B must both turn off.
The problem is that the actions of the automation act as a trigger for itself. This means that if A is turned on, C turns on and C turning on subsequently triggers B to turn on. Everything turns on or off.
I have put a 5s delay at the end of the timer and set it to “single” mode. This has solved the undesired behaviour. I would prefer not to have the delay at all - just in case the light is flicked on and off by accident. Is there a way to prevent triggers from otherwise being generated by an automation? Sort of like an “island mode” for an automation…
There are blueprints that solve this problem in the blueprint section. There’s a few custom integrations that do this as well. If you just want an automation, here’s one that I use that solves this problem too:
- alias: Toggle - Cabinet String Lights
id: toggle_cabinet_string_lights
mode: parallel
trigger:
- platform: state
entity_id: &cabinet_string_entities
- switch.kitchen_cabinet
- switch.wled_all_cabinets
variables:
entities: *cabinet_string_entities
state_list:
- 'on'
- 'off'
continue: >
{{ trigger | default(none) is not none and trigger.to_state is defined and trigger.from_state is defined }}
to_state: >
{{ trigger.to_state.state | default(none) if continue else none }}
targets: >
{{ expand(entities) | rejectattr('entity_id', 'eq', trigger.entity_id) | rejectattr('state', 'eq', to_state) | map(attribute='entity_id') | list if continue else [] }}
condition:
- condition: template
value_template: "{{ continue and to_state in state_list and targets | count > 0 }}"
action:
- service: switch.turn_{{ to_state }}
target:
entity_id: "{{ targets }}"
This can only be added as a yaml automation, you cannot add this via the UI. If this is too complicated, I recommend using one of the blueprints in the blueprint section of the forums.
