home-assistant-zigbee-esphome

home-assistant-zigbee-esphome is a skill for Claude Code, Codex from magnusoverli/opencode. It costs 96 tokens per session (1,624 once invoked), scanned A, original, Unlicense.

A guide for managing Zigbee and ESPHome smart-home devices through Home Assistant. Zigbee is a wireless standard for home devices, while ESPHome is firmware used by many DIY devices.

In plain words
What is it for?
Use it to inspect devices, rename them safely, remove stale devices, map the Zigbee mesh, or monitor firmware updates.
Why use it?
It helps keep device names, automations, dashboards, firmware updates, and the Zigbee network consistent across Home Assistant and related device systems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

home-assistant-zigbee-esphome scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Zigbee and ESPHome devices

Firmware updates

Use watch_firmware_update for device firmware — ESPHome, WLED, Zigbee, and anything else exposing an update.* entity. One call starts the update, monitors progress in real time, and reports the result:

watch_firmware_update(entity_id="update.device_firmware", start_update=true)

Do not poll get_states in a loop instead; this tool exists because that pattern burns context and misses the failure modes.

System updates (Core, OS, Supervisor, add-ons) are a different path:

1. get_available_updates()               -> what needs updating
2. update_component(component="core")    -> start, returns job_id
3. get_update_progress(job_id="...")     -> monitor

Ask before starting either. A firmware update can brick a device on a bad power supply, and a Core update takes the instance offline. Check get_backup_posture first when the update is a large one.

Inspecting a device

zigporter inspect "Device Name" --json (or zigporter inspect sensor.entity_id --json) is the one command that cross-references ZHA, Zigbee2MQTT and the Home Assistant registry at once — use it before concluding anything about a Zigbee device. zigporter list-devices --json inventories everything; zigporter list-z2m --json needs the Z2M URL configured in the add-on settings.

For the signal-quality picture, zigporter network-map --format table prints the mesh in the terminal, and zigporter network-map --output mesh.svg writes an SVG. Weak lqi, a device routing through a distant parent, or a router that has gone offline explain a large share of "the sensor keeps dropping out" reports.

zigporter check verifies connectivity before you trust any of the above.

Renaming — the thing zigporter is for

hab entity update and hab device update rename one thing and leave every reference to the old ID dangling. zigporter cascades: it patches automations, scripts, scenes and every Lovelace dashboard in one atomic pass.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
