home-assistant	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.	Claude Code	2.1.0	2026-06-24

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):

# ha-london (default)
python3 .claude/home-assistant.py [command] [options]

# ha-sofia
python3 .claude/home-assistant-sofia.py [command] [options]

SSH Access (ha-sofia only)

ha-sofia supports SSH for direct configuration management.

Connection

ssh vbarzin@192.168.1.8

Configuration Path

/config/

Common SSH Tasks

# 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:

python3 .claude/home-assistant.py on light.living_room

To check ha-sofia configuration:

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
cover	Blinds/covers	open, close, set position
lock	Locks	lock, unlock
media_player	Media devices	play, pause, volume
input_boolean	Helper toggles	on, off
input_number	Helper numbers	set value
input_select	Helper dropdowns	select option
script	Scripts	run
scene	Scenes	activate
automation	Automations	trigger, on, off

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).

ha-london Knowledge Map

Overview

• HA Version: 2026.5.2 on Home Assistant OS (HAOS — managed appliance, NOT a docker run container). Latest is 2026.6.4 (update available, deliberately not applied).
• Location: London, UK
• Platform: Raspberry Pi 4, HA OS
• Access from the Sofia devvm: london is remote — homelab ha ssh --instance london generally WON'T connect (ADR-0012). Drive it via the API: homelab ha token --instance london + https://ha-london.viktorbarzin.me/api/..., and the WebSocket API wss://ha-london.viktorbarzin.me/api/websocket for dashboards / config-entries / HACS installs.
• SSH (only from the London LAN): ssh hassio@192.168.8.103 (requires sudo for file access)
• Config path: /config/
• 3 tracked people: Viktor Barzin, Anca Milea, Gheorghe Milea
• Zone: London (home)

Dashboards (redesigned 2026-06-24)

Glossary (HA terms — keep distinct):

• Dashboard = a sidebar entry (Overview, Air Quality, Map). Sidebar order is a per-USER frontend preference, not in any dashboard config.

• View = a tab inside a dashboard. View order is global (stored in the dashboard config).

• Card = a widget inside a view.

• Overview (lovelace, the default): responsive sections views, styled with Mushroom + mini-graph-card.

  • Home tab: Who's home · Comfort & Air (CO₂/temp/humidity/PM2.5/VOC chips + CO₂ and temp/humidity trend graphs + link to Air Quality) · Cowboy (battery/range/last-ride) · Energy (5 Kasa plugs + power trend) · Quick actions (Netflix/Stremio/Night).
  • More tab: Network (GL-MT6000 router) · System (HA version/update, last backup, RPi power) · Phones.

• Air Quality (air-quality): deep-dive (views: Home, Detailed). (detialed→detailed path typo fixed 2026-06-24.)

• Built via the WS lovelace/config/save API (london is remote — no SSH path).

Key Systems

1. Smart Plugs (TP-Link Kasa) — Energy Monitoring

Named plugs with power/energy tracking:

Name	Entity	Usage/month	Purpose
Thor	switch.thor	6.4 kWh	Server/NAS
Pikkachu	switch.pikkachu	4.8 kWh	Water cooler
Michelle	switch.emeter_plug	0.3 kWh	—
Livia	switch.livia	0.07 kWh	—
Jinx	switch.jinx	0.02 kWh	—
Projector plug	switch.tapo_p100	unavailable	Tapo P100

2. Air Quality (Apollo AIR-1 via ESPHome)

• sensor.apollo_air_1_fa2d34_co2: CO2 level
• sensor.apollo_air_1_fa2d34_sen55_temperature: Temperature
• sensor.apollo_air_1_fa2d34_sen55_humidity: Humidity
• PM1.0/2.5/4.0/10 particulate sensors
• VOC, NOx, ammonia, CO, ethanol, hydrogen, methane, NO2 gas sensors

3. Cowboy E-Bike (elsbrock/cowboy-ha)

Bike named "Classic Performance" → entities are sensor.classic_performance_* (26 total). The old sensor.bike_* names are GONE (they were the dead jdejaegh integration).

• sensor.classic_performance_remaining_battery: Battery % (was sensor.bike_state_of_charge)
• sensor.classic_performance_remaining_range: Range km
• sensor.classic_performance_mileage: Total km (was sensor.bike_total_distance)
• sensor.classic_performance_saved_co2: Lifetime CO2 saved (was sensor.bike_total_co2_saved)
• Plus _distance_today, _last_trip_*, _battery_health, device_tracker.classic_performance, etc.
• GOTCHA: live battery/range/mileage read unknown while the bike is parked/asleep — Cowboy only reports live SoC when awake (ridden/charging); trip-history + distance_today stay live regardless.
• Auth: account email+password (no AWS Cognito — that was the dead jdejaegh/cowboybike lineage). Setup via UI config flow / REST config_entries/flow. Creds in Vaultwarden item "cowboy bike" (homelab vault get "cowboy bike").

4. Uptime Monitoring (UptimeRobot)

• sensor.blog: blog uptime
• sensor.valchedrym: Valchedram site uptime
• switch.blog, switch.valchedrym: monitoring toggles

5. Oral-B Toothbrush (BLE)

• sensor.smart_series_6000_83d3_*: mode, pressure, sector, time

6. Network Device Tracking (~100 devices)

• Router-based MAC tracking (many unnamed)
• Named: Viktor's iPhone15Pro, Anca's iPhone13Pro, Apple Watch, Amazon Fire, iRobot, Portal, Living-Room TV

7. Media & Entertainment

• Projector + debug bridge: unavailable (Tapo plug off)
• Scripts: script.start_netflix, script.start_stremio
• Scene: scene.night (turns off Livia + Michelle plugs)

Custom Components (HACS integrations)

• cowboy (elsbrock/cowboy-ha v1.2.0): Cowboy e-bike — revived 2026-06-24. The old jdejaegh/home-assistant-cowboy repo is dead (404); don't chase it.
• hildebrandglow_dcc: UK smart meter DCC energy — DISABLED by user (config entry disabled_by: user), not broken.

HACS frontend cards (plugins)

• Mushroom (piitaya/lovelace-mushroom), mini-graph-card (kalkih/mini-graph-card), plotly-graph-card (dbuezas/lovelace-plotly-graph-card) — used by the redesigned Overview. Install over WS hacs/repository/download; resources auto-register in storage mode.

Integrations

ESPHome, TP-Link Kasa, Tapo, UptimeRobot, Cowboy (elsbrock), Oral-B BLE, Ookla Speedtest (exposes only an update entity, no live speed sensors), HACS, OpenRouter (free LLMs), Piper (TTS), Whisper (STT), Android TV/ADB.

• Disabled by user (NOT broken): met + metoffice (weather — so weather.* entities are ABSENT), roomba (Rumi vacuum), hildebrandglow_dcc (energy).
• Failing: tplink Tapo P100 projector plug — setup_retry, 403 KLAP handshake from 192.168.8.108 (plug off / firmware). Left as-is.

AI / Voice Assistants

• 5 free LLM conversation agents: Google Gemma 3 27B, Meta Llama 3.2 3B, Mistral Devstral 2, OpenAI GPT-OSS-20B, Z.AI GLM 4.5 Air
• Local voice: Piper (TTS) + Whisper (STT)
• Google Translate TTS

Automations (10)

• Water cooler on/off scheduling (07:00 on, 00:30 off)
• Michelle plug auto-off when idle (<70W)
• Apollo AIR-1 RGB LED: CO2 indicator (on in morning, off at 22:00)
• Cowboy e-bike low battery notification (ntfy + iPhone push)
• Anca arrival/departure notifications
• Night scene: turns off Livia + Michelle

Platform (HAOS — ignore any legacy docker run snippet)

ha-london runs Home Assistant OS (managed appliance), NOT a hand-run Docker container. There is no docker run homeassistant/home-assistant to manage. Install HACS components over the WebSocket API (hacs/repository/download with the repo's HACS id), then restart via POST /api/services/homeassistant/restart — a HAOS restart drops automations for ~1–2 min and resets sensor.uptime (use that as the "back up" marker).
