Home Assistant Automation

Reference skill for Home Assistant configuration and automation.

First Step: Clarify Platform

If the user's request does NOT explicitly mention "YAML", "Home Assistant automation", or "HA config", ASK:

"Do you want this as:

Home Assistant YAML (automations.yaml, scripts.yaml, blueprints)

Node-RED flow (visual, drag-drop, importable JSON)

ESPHome config (device firmware for ESP32/ESP8266)"

NEVER assume YAML. A request like "make a motion light" could be any of these. Only proceed with this skill if user confirms Home Assistant YAML.

Overview

Core principle: Never generate YAML without understanding the user's intent. Automation vs blueprint, UI editor vs YAML files, and entity naming conventions must be clarified first.

Announce at start: "I'm using the ha-yaml skill to help you configure your Home Assistant automation."

Context: This skill requires intent clarification before any YAML generation. Automations are specific to a user's setup; blueprints are reusable templates. The format (UI vs YAML) affects how entities are referenced.

The Iron Law

CLARIFY INTENT BEFORE GENERATING ANY YAML

Ask: Automation or Blueprint? Format: UI or YAML? Never assume. Never skip these questions.

The Process

dot

digraph automation_flow {
    rankdir=TB;
    node [shape=box, style=rounded];

    start [label="User request", shape=doublecircle];
    clarify_type [label="Ask: Automation or Blueprint?"];
    clarify_format [label="Ask: UI editor or YAML files?"];
    clarify_output [label="Ask: Output method?"];
    intent_clear [label="Intent clear?", shape=diamond];
    read_refs [label="Read relevant references"];
    generate [label="Generate YAML"];
    checklist [label="Run pre-completion checklist"];
    done [label="Deliver configuration", shape=doublecircle];

    start -> clarify_type;
    clarify_type -> clarify_format;
    clarify_format -> clarify_output;
    clarify_output -> intent_clear;
    intent_clear -> read_refs [label="yes"];
    intent_clear -> clarify_type [label="no - ask more"];
    read_refs -> generate;
    generate -> checklist;
    checklist -> done;
}

Red Flags - STOP Immediately

These thoughts mean you're about to violate this skill:

Thought	Reality
"Request is clear enough"	NO. Always ask automation vs blueprint, UI vs YAML
"They want an automation"	ASK. Could be blueprint, script, or scene
"Simple request needs simple answer"	NO. Simple requests still need intent clarification
"User just wants code quickly"	NO. Wrong code is slower than asking first
"I'll provide options instead"	NO. Ask questions, don't provide multiple YAML versions
"Sunset/motion light is obvious"	NO. Which lights? What brightness? Conditions?
"YAML format is standard"	ASK. Many users prefer UI editor format
"This entity_id looks right"	VERIFY. Users have different naming conventions
"I'll skip the questions for simple requests"	NO. This IS the rationalization the skill forbids
"service_template works fine"	DEPRECATED. Use `service: "{{ ... }}"`
"data_template is cleaner"	DEPRECATED. Use `data:` with templates
"states() is the easiest approach"	SLOW. Filter by domain: `states.sensor`

If you're thinking ANY of these, STOP. Ask questions first.

FIRST STEP: Clarify Intent (MANDATORY)

STOP! You MUST ask these questions before generating ANY configuration:

Automation or Blueprint?
- Automation: Specific to their setup, uses their entity names
- Blueprint: Reusable template others can import
Format?
- UI Editor (Settings > Automations)
- YAML files (automations.yaml, packages/)
Output method?
- Save to folder - Write file to the current working directory (where Claude is running)
- Copy from chat - Display code for user to copy manually
HA Version? (for deprecated syntax awareness)

Do NOT skip these questions. Do NOT assume defaults.

MANDATORY First Response Format

Your first response MUST follow this exact pattern:

I'll help you create [brief description]. Let me clarify a few things first:

1. **Type:** Automation (specific to your setup) or Blueprint (reusable template)?
2. **Format:** UI editor (Settings > Automations) or YAML files?
3. **Entities:** Which specific entity IDs? (e.g., light.living_room, sensor.motion)
4. **Options:** [context-specific questions like brightness, conditions, timing]

THEN STOP. Wait for user answers. Do NOT generate YAML until you have answers.

Violation example (DO NOT DO THIS):

Here's the automation:
automation:
  - alias: "..."

Correct example:

I'll help you create a sunset light automation. Let me clarify:
1. Automation or Blueprint?
2. UI editor or YAML file?
3. Which lights? (entity IDs like light.living_room)
4. Any brightness preference or conditions (only when home)?

Common Mistakes

Trigger Issues

state
without
from
/
to
- Triggers on ALL changes including
```
unavailable
```
→ use
```
to: "on"
```
explicitly
Template triggers without
value_template
- Syntax error; use
```
value_template: "{{ ... }}"
```
Missing
id
in multi-trigger - Can't distinguish which trigger fired; add
```
id: motion_detected
```
Numeric comparisons as strings -
```
"10"
```
>
```
"9"
```
is false; use
```
| int
```
or
```
| float
```
filters

Condition Issues

and
/
or
without
condition:
- Must specify condition type:
```
condition: and
```
Template condition syntax - Use
```
value_template:
```
, not
```
condition: "{{ ... }}"
```
State comparisons - States are strings; use
```
| int
```
for numeric comparisons

Action Issues

service_template
deprecated - Use
```
service: "{{ ... }}"
```
directly
data_template
deprecated - Use
```
data:
```
with templates inside
entity_id
in data - Should be under
```
target:
```
block since HA 2021.x
Missing
continue_on_error
- Long automations fail silently; add error handling

Template Issues

states()
without domain - Returns ALL entities (slow); use
```
states.sensor
```
or
```
states('sensor.name')
```
now()
in template sensor - Only updates on state change; use
```
scan_interval
```
or trigger-based
Missing
default
filter - Errors when entity unavailable; use
```
| default(0)
```
Float precision - Use
```
| round(2)
```
for display values

Blueprint Issues

Missing
selector
types - Inputs need proper selectors for UI
Hardcoded entity_ids - Use
```
!input
```
for all user-configurable values
No default values - Optional inputs need
```
default:
```
specified

Security Considerations

Secrets - Use
```
!secret
```
for all credentials, API keys, and sensitive data
Exposed entities - Limit what's exposed to Alexa/Google/Nabu Casa
Remote access - Use Nabu Casa or secure reverse proxy with SSL
Blueprints - Review imported blueprints before using; they can execute arbitrary services
Shell commands - Never use user input in
```
shell_command:
```
without validation
REST commands - Use
```
!secret
```
for API endpoints and tokens

Automation Quick Pattern

yaml

automation:
  - alias: "Descriptive Name"
    id: unique_automation_id  # Required for UI editing
    trigger:
      - platform: state
        entity_id: binary_sensor.motion
        to: "on"
        id: motion_detected  # For multi-trigger identification
    condition:
      - condition: time
        after: sunset
    action:
      - service: light.turn_on
        target:
          entity_id: light.living_room
        data:
          brightness_pct: 80

Blueprint Quick Pattern

yaml

blueprint:
  name: "Blueprint Name"
  description: "What this blueprint does"
  domain: automation
  input:
    motion_sensor:
      name: "Motion Sensor"
      description: "Select the motion sensor"
      selector:
        entity:
          domain: binary_sensor
          device_class: motion
    target_light:
      name: "Light"
      selector:
        target:
          entity:
            domain: light

trigger:
  - platform: state
    entity_id: !input motion_sensor
    to: "on"

action:
  - service: light.turn_on
    target: !input target_light

Modern Syntax (HA 2021+)

Service Calls

yaml

# Old (deprecated)
service_template: "{{ 'light.turn_on' if is_on else 'light.turn_off' }}"
data_template:
  entity_id: light.living_room

# New (correct)
service: "{{ 'light.turn_on' if is_on else 'light.turn_off' }}"
target:
  entity_id: light.living_room
data:
  brightness: "{{ brightness_value }}"

Template Sensors

yaml

# Old (deprecated)
sensor:
  - platform: template
    sensors:
      my_sensor:
        value_template: "{{ states('sensor.input') }}"

# New (correct) - template integration
template:
  - sensor:
      - name: "My Sensor"
        state: "{{ states('sensor.input') }}"
        unit_of_measurement: "°C"

Pre-Completion Checklist

Before declaring the configuration complete, verify:

Intent Verification

Confirmed: automation vs blueprint vs script vs scene
Confirmed: UI editor vs YAML file format
Confirmed: output method (save vs copy)
HA version considered for syntax compatibility

YAML Syntax

No deprecated
```
service_template
```
(use
```
service:
```
with template)
No deprecated
```
data_template
```
(use
```
data:
```
with templates)
```
entity_id
```
under
```
target:
```
block (not in
```
data:
```
)
All template syntax uses
```
{{ }}
```
correctly
Quotes around string states:
```
to: "on"
```
not
```
to: on
```

Templates

```
states()
```
filtered by domain where possible
```
default
```
filter on templates accessing external entities
Numeric comparisons use
```
| int
```
or
```
| float
```
Complex templates tested mentally for edge cases

Automations

```
id:
```
present for UI editor compatibility
```
alias:
```
is descriptive and unique
Trigger
```
id:
```
for multi-trigger automations
```
continue_on_error: true
```
where appropriate

Blueprints

All variable values use
```
!input
```
Proper
```
selector:
```
types for all inputs
```
default:
```
values for optional inputs
```
description:
```
for all inputs

Safety

No hardcoded credentials (use
```
!secret
```
)
Attribution header included
User's entity naming convention respected

Integration

Pairs with:

esphome - Create ESPHome device configurations
ha-integration - Develop custom Python integrations

Typical flow:

Device → esphome/ha-integration → Home Assistant → ha-yaml (this skill)

Cross-references:

For ESPHome device firmware → use
```
