Viktor Barzin 48225f2dea homelab CLI v0.7: add ha token + ha ssh for Home Assistant 
Mined another devvm user's Claude sessions for repeated, hand-rolled command
patterns worth absorbing into the shared CLI. The dominant signal was Home
Assistant "Sofia" work: a `kubectl | base64 | jq` token-extraction pipeline
re-derived ~420x, and a bespoke non-interactive `ssh -o …` invocation reinvented
~30x — every session. The existing `home-assistant-sofia.py` already covers the
API but goes unused from an arbitrary cwd (needs an env var set + a cwd-relative
path), so agents bypassed it and hand-rolled everything.

Add two verbs covering exactly the gaps the `ha` MCP can't (entity state/control
stays with the MCP):
- `ha token [--instance sofia|london]` (read): resolves the long-lived API token
  live from k8s secret openclaw/openclaw-secrets via the ambient kubeconfig — no
  pre-set env var. Composes as `curl -H "Authorization: Bearer $(homelab ha token)"`.
- `ha ssh [--instance sofia|london] -- <cmd>` (write): deterministic
  non-interactive ssh to the HA host using the invoking user's key.

Also fix the root cause: `home-assistant-sofia.py` now falls back to
`homelab ha token` when its env var is unset (works from any directory), and the
home-assistant skill points agents at these verbs + `homelab metrics query`
instead of hand-rolled curls. README + ADR-0012 + AGENTS.md updated per the
per-verb-group convention.

Control Home Assistant smart home devices and automations. Use when:
(1) User asks to turn on/off lights, switches, or devices,
(2) User asks about the state of sensors, devices, or entities,
(3) User says "turn on the lights", "set temperature", "lock the door",
(4) User asks to run a scene or script,
(5) User asks "what devices are on?" or "is the door locked?",
(6) User mentions smart home, IoT, or home automation.
There are TWO Home Assistant deployments: ha-london (default) and ha-sofia.
Always use Home Assistant for smart home control.

# Home Assistant Control
## Problem
Need to control smart home devices, check sensor states, or run automations via Home Assistant.
## Context / Trigger Conditions
- User asks to control lights, switches, covers, climate, etc.
- User asks about device states ("is the light on?", "what's the temperature?")
- User wants to run a scene or script
- User mentions turning things on/off
- User asks about smart home devices
## Deployments
There are **two** Home Assistant instances:
| Instance | URL | SSH | Default? |
|----------|-----|-----|----------|
| **ha-london** | `https://ha-london.viktorbarzin.me` | `ssh hassio@192.168.8.103` | Yes |
| **ha-sofia** | `https://ha-sofia.viktorbarzin.me` | `ssh vbarzin@192.168.1.8` | No |
- **Default**: ha-london (use unless user specifies "sofia" or "ha-sofia")
- **Aliases**: "ha" or "HA" = ha-london. "ha sofia" or "ha-sofia" = ha-sofia.
## Prerequisites
- Python 3 with `requests` package available (installed via PYTHONPATH or system packages)
- Environment variables for each instance:
- **ha-london**: `HOME_ASSISTANT_URL` and `HOME_ASSISTANT_TOKEN`
- **ha-sofia**: `HOME_ASSISTANT_SOFIA_URL` and `HOME_ASSISTANT_SOFIA_TOKEN`
- If those env vars aren't set (e.g. you're not in the infra repo / Claude venv), don't hand-roll a `kubectl | base64 | jq` token pipeline — use the global **`homelab` CLI** instead (on `$PATH` in any directory):
## homelab CLI (preferred — works from any directory)
- **Token**: `homelab ha token [--instance sofia|london]` resolves the long-lived API token live from the cluster. Use it directly in curl: `curl -H "Authorization: Bearer $(homelab ha token)" https://ha-sofia.viktorbarzin.me/api/states`. (The `home-assistant-sofia.py` script also auto-falls-back to this when its env var is unset.)
- **Host shell** (ha-sofia): `homelab ha ssh -- <cmd>` runs a command on the HA host with deterministic non-interactive ssh (no host-key prompt) — e.g. `homelab ha ssh -- "sudo docker ps"`, `homelab ha ssh -- "cat /config/configuration.yaml"`. Replaces bespoke `ssh -o StrictHostKeyChecking=no …` invocations.
- **Cluster metrics/logs** (not HA-specific): prefer `homelab metrics query "<promql>"` / `homelab logs query "<logql>"` over hand-rolled `curl …/api/v1/query`, and `homelab claim`/`release` over calling `scripts/presence` directly.
## API Control
### Scripts
| Instance | Script |
|----------|--------|
| ha-london | `.claude/home-assistant.py` |
| ha-sofia | `.claude/home-assistant-sofia.py` |
### Execution Pattern (CRITICAL)
Run the scripts directly with python3 (env vars are set in the environment):
```bash
# ha-london (default)
python3 .claude/home-assistant.py [command] [options]
# ha-sofia
python3 .claude/home-assistant-sofia.py [command] [options]
```
### Available Commands
#### List Entities
```bash
# List all entities
python .claude/home-assistant.py list
# List by domain
python .claude/home-assistant.py list --domain light
python .claude/home-assistant.py list --domain switch
python .claude/home-assistant.py list --domain sensor
python .claude/home-assistant.py list --domain climate
python .claude/home-assistant.py list --domain cover

python .claude/home-assistant.py search "door"
```
#### Get Entity State
```bash
python .claude/home-assistant.py state light.living_room
python .claude/home-assistant.py state sensor.temperature
python .claude/home-assistant.py state --json light.living_room
```
#### Control Entities
```bash

python .claude/home-assistant.py scene movie_night
python .claude/home-assistant.py scene scene.good_morning
# Run a script
python .claude/home-assistant.py script bedtime_routine
python .claude/home-assistant.py script script.welcome_home
```
#### Call Any Service
```bash
# Generic service call
python .claude/home-assistant.py service light turn_on --entity light.kitchen --data '{"brightness": 255}'
python .claude/home-assistant.py service climate set_hvac_mode --entity climate.living_room --data '{"hvac_mode": "heat"}'
python .claude/home-assistant.py service media_player play_media --entity media_player.tv --data '{"media_content_id": "...", "media_content_type": "video"}'
```
#### List Services
```bash
# List all available services
python .claude/home-assistant.py services
# Filter by domain
python .claude/home-assistant.py services --domain light
python .claude/home-assistant.py services --domain climate
```
#### Send Notifications
```bash
python .claude/home-assistant.py notify "Door left open!"
python .claude/home-assistant.py notify "Motion detected" --title "Security Alert"
python .claude/home-assistant.py notify "Hello" --target notify.mobile_app
```
## SSH Access (ha-sofia only)
ha-sofia supports SSH for direct configuration management.
### Connection
```bash
ssh vbarzin@192.168.1.8
```
### Configuration Path
```
/config/
```
### Common SSH Tasks
```bash
# Read configuration
ssh vbarzin@192.168.1.8 "cat /config/configuration.yaml"
# Check HA logs (note: live log is inside HA Core container, not always accessible)
ssh vbarzin@192.168.1.8 "tail -50 /config/home-assistant.log.1"
# List config files
ssh vbarzin@192.168.1.8 "ls /config/*.yaml"
# Read automations/scenes/scripts
ssh vbarzin@192.168.1.8 "cat /config/automations.yaml"
ssh vbarzin@192.168.1.8 "cat /config/scenes.yaml"
ssh vbarzin@192.168.1.8 "cat /config/scripts.yaml"
# Check secrets (keys only, not values)
ssh vbarzin@192.168.1.8 "cat /config/secrets.yaml"
```
### SSH Limitations
- The SSH add-on runs in a separate container — `ha core logs` returns 401
- Docker socket is not accessible — can't use `docker logs`
- Live `home-assistant.log` may not be visible (written inside HA Core container)
- Rotated logs (`.log.1`, `.log.old`) are accessible
## Complete Example
To turn on the living room light on ha-london:
```bash
python3 .claude/home-assistant.py on light.living_room
```
To check ha-sofia configuration:
```bash
ssh vbarzin@ha-sofia.viktorbarzin.lan "cat /config/configuration.yaml"
```
## Common Entity Domains
| Domain | Description | Common Actions |
|--------|-------------|----------------|
| `light` | Lights | on, off, toggle, set brightness |
| `switch` | Switches | on, off, toggle |
| `sensor` | Sensors | state (read-only) |
| `binary_sensor` | Binary sensors | state (read-only) |
| `climate` | Thermostats | set temperature, set mode |

## Verification
- Commands print confirmation message on success
- Use `state` command to verify entity changed
- Exit code 0 = success, 1 = error
## Common Errors
| Error | Cause | Fix |
|-------|-------|-----|
| `HOME_ASSISTANT_URL and HOME_ASSISTANT_TOKEN must be set` | Env vars not set | Ensure `HOME_ASSISTANT_URL` and `HOME_ASSISTANT_TOKEN` are in the environment |
| `404 Not Found` | Entity doesn't exist | Use `search` command to find correct entity ID |
| `401 Unauthorized` | Token invalid/expired | Generate new long-lived token in HA |
| `Connection refused` | HA not reachable | Check URL and network connectivity |
## Notes
1. **Entity IDs are case-sensitive** - use `search` to find exact IDs
2. **Token must have sufficient permissions** - ensure token has access to all entities
3. **Some entities require specific data** - use `services` command to see required fields
4. **Two instances**: ha-london (default, K8s), ha-sofia (SSH + API)
5. **ha-sofia SSH**: Uses default SSH key, user `vbarzin`, resolve DNS via `192.168.1.2`. Only reachable from local Sofia network (not remotely).
