The AI cross-referenced all sensors against existing automations, revealing that 145 of 147 sensors were driving no automations. The audit surfaced actionable improvements including a CO2 alert for the office (which was at 1,571 ppm), a backup failure monitor, and cleanup of stale device records. It also flagged impractical suggestions like an internet-down push notification. The key takeaway is that AI-assisted auditing helped surface months of silent failures and unused sensor potential in a setup that had been largely neglected since initial configuration. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What CO2 concentration level starts to noticeably hurt concentration in an office? Concentration in a room noticeably declines once carbon dioxide levels exceed roughly 1,400 ppm, according to studies referenced when a home office sensor was found reading 1,571 ppm and a kitchen sensor 1,802 ppm. This level was used to justify setting up an automation that triggers a nudge alert to open windows or adjust fans when air quality drops. _Anyone tuning smart home air quality alerts can find similar hands-on setups curated on daily.dev._ ### How can I use an AI coding assistant to find unused sensors and automations in my Home Assistant setup? Giving an AI coding assistant like Claude Code read-only MCP access to a Home Assistant instance lets it cross-reference the entire entity registry against existing automations to flag unused sensors. One audit found 145 of 147 sensors and 66 of 68 binary sensors had no automation using them, plus stale device records and a broken authentication on an LG appliance integration. _Developers experimenting with AI-assisted home automation audits can track similar workflows on daily.dev._ ## Similar posts on daily.dev - [Claude Code found the quiet problems hiding in my Home Assistant setup, and I've been ignoring them for months](https://daily.dev/posts/claude-code-found-the-quiet-problems-hiding-in-my-home-assistant-setup-and-i-ve-been-ignoring-them--x2wcdkbpd) · XDA Developers · 0 upvotes · 0 comments - [I gave Claude Cowork access to my Home Assistant config, and it unlocked automations I didn't know were possible](https://daily.dev/posts/i-gave-claude-cowork-access-to-my-home-assistant-config-and-it-unlocked-automations-i-didn-t-know-w-t16yakx3r) · XDA Developers · 0 upvotes · 0 comments - [My home lab finally has an AI brain, and it's Claude Code through MCP](https://daily.dev/posts/my-home-lab-finally-has-an-ai-brain-and-it-s-claude-code-through-mcp-1xv4ifhkl) · XDA Developers · 0 upvotes · 0 comments - [Using Claude to audit Design System and making it future proof\!](https://daily.dev/posts/using-claude-to-audit-design-system-and-making-it-future-proof--82jlwmlpe) · Medium · 0 upvotes · 0 comments --- Tags: [#tech-news](https://daily.dev/tags/tech-news), [#mcp](https://daily.dev/tags/mcp), [#claude-code](https://daily.dev/tags/claude-code) [View this post on daily.dev](https://daily.dev/posts/my-home-assistant-was-missing-half-its-potential-until-claude-code-showed-me-what-it-could-actually--bcjy22jwg) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"My Home Assistant was missing half its potential until Claude Code showed me what it could actually do","url":"https://daily.dev/posts/my-home-assistant-was-missing-half-its-potential-until-claude-code-showed-me-what-it-could-actually--bcjy22jwg","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/my-home-assistant-was-missing-half-its-potential-until-claude-code-showed-me-what-it-could-actually--bcjy22jwg"},"datePublished":"2026-07-10T11:33:23.781Z","dateModified":"2026-09-13T20:40:33.894Z","description":"A Home Assistant user with 317 entities and only 3 automations used Claude Code with MCP read-only access to audit their entire smart home setup.
