esphome

esphome is a skill for Claude Code from larsboes/Axon. It costs 148 tokens per session (1,251 once invoked), scanned A, original, MIT.

A workflow for building and sending ESPHome firmware to home-automation devices over Wi-Fi, then viewing their logs. ESPHome is software for configuring firmware on devices such as sensors and controllers.

In plain words
What is it for?
Use it to list device configurations, compile firmware, upload it over the network, check the dashboard, and stream device logs.
Why use it?
It handles the container, remote-host, and network steps needed to compile and update devices without a separate local ESPHome installation.

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

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 7d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

esphome

Build and OTA-flash ESPHome nodes through the containerized esphome CLI on the home-automation host. espctl is a thin wrapper: node builds/flashes run via docker exec over SSH; the dashboard is polled directly only for a quick version reachability check. Node YAMLs live on the host in the directory bind-mounted to /config in the container.

Container assumption

This drives a Docker container named esphome (override with $ESPHOME_CONTAINER) — typically a service in the host's docker-compose/compose.yaml, with the host's ESPHome config dir mounted to /config. Every command shells docker exec <container> esphome … over SSH; there is no bare local ESPHome install in the loop. The dashboard normally listens on :6052. For OTA to work, the ESPHome service must bind the LAN IP (--address in the compose service), and exposure of :6052 should be restricted to the LAN.

Setup (once)

  1. On the host: run the esphome container (compose service named esphome) with the config dir mounted to /config, and ensure key-based SSH access to the host (the tool uses BatchMode=yes — no password prompt).
  2. In the overlay config: the connection facts live in the committed overlay at <overlay>/config/home-assistant.vars (path via $AXON_HOME_ROOT, default the active deployment overlay): ESPHOME_SSH (an ssh target such as user@host), ESPHOME_URL (the dashboard base URL, e.g. http://host:6052), and ESPHOME_CONTAINER (the container name). All three are non-secret and committed there; each can be overridden per-run via the matching $ESPHOME_* env var (env wins over the config file).
  3. No secret for this skill. It reaches the container over SSH with key auth — there is no password or token, so there is no Bitwarden item to provision. (If a secret is ever needed later, add a bw fetch then; today there is none.)

Run

The tool reads its connection facts from the overlay config — no unlock step:

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.

esphome is a skill published in the GitHub repository larsboes/Axon (1 stars, last pushed today), licensed MIT. It adds 148 tokens to every session and 1,251 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
