Claude and Codex vibe coding are putting your smart home at risk
Vibe coding allowed everyone to create their own custom components for Home Assistant. Many of these integrations are shared on forums for other people to use, but using them could put your smart home at risk.
Vibe coding lets anyone create custom components
From idea to integration with no coding required
Vibe coding has made it possible for anyone to generate working code, even if they don’t have the first idea of coding. Using powerful coding tools like Claude Code or Codex, you can describe your idea in natural language and the AI will write the code for you.
Home Assistant integrations are built from code, so you can use these AI tools to create your own custom components that can do anything you can think of. If you have an idea for an integration that doesn’t already exist, you can describe what you want it to do to Claude or Codex, and it will generate the code for you. There are many open source Home Assistant integrations that AI can use as a source.
Some members of the Home Assistant community use these tools to create custom components, and many share them on forums. If you see a post for an integration that promises to do something useful, you can install it and have it working in Home Assistant in moments.
Security Risks Lurking in Custom Integrations
AI-generated code can pose serious problems
While on the surface these integrations may appear useful and appear to do what they are intended to do, there may be serious problems lurking beneath the surface. These ambiance-coded integrations can put your security at risk in several ways.
The integration may require things like login information, API key, or access token to function. This is something that many official integrations will ask for, so you might not think twice before doing it. However, there is a risk that an ambiance-coded integration could mishandle these credentials and potentially expose them, putting your security at risk.
Why I’m learning to code in the era of vibe coding
I’m not giving in to the vibrations yet.
The integration can use a webhook that accepts external commands without verifying the source, potentially allowing anyone to control your smart home, or it can send data back and forth to the cloud unencrypted. These are problems that someone with coding knowledge would be more likely to avoid.
If this sounds alarmist, just look at the Huntarr dashboard example. Huntarr was a flavor-coded management tool for self-hosted applications, and a public security review revealed several serious flaws. According to the review, some API endpoints could be accessed without authentication, including endpoints that could expose or modify settings, and responses could return API keys and credentials stored in clear text, meaning sensitive details could potentially be exposed.
Security is not the only problem
Vibe-coded integrations may be unstable or worse
These mood-coded apps can put your security at risk, but that’s not the only problem. They can also be unstable, making your Home Assistant setup worse.
For example, ambiance-coded apps may call an API every few seconds, causing your IP address to be blocked. They might try to pull data from battery-powered devices too frequently, thereby draining the batteries faster. They can also create a mess of new entities that are misnamed, duplicated, or have the wrong classes, which can be a real headache to solve.
These ambiance-coded integrations might not be maintained, meaning a future Home Assistant update could break them altogether. They can also handle errors poorly, flooding your logs with repeated messages.
There are even mood-coded MCP tools that can give AI chatbots full access to Home Assistant, with the ability to read and write. These could potentially completely break your Home Assistant setup by removing the wrong things or even your entire setup. Anecdotal evidence suggests that these types of catastrophic failures are not uncommon.
How to protect your Home Assistant configuration
Treat third-party code with skepticism
This is not to say that using AI coding tools is inherently bad. In the right hands, they can be very useful tools that can help speed up the process of writing good, clean code. However, fully vibe-coded integrations can be a real risk, although there are ways to protect yourself.
Try to use official integrations whenever possible. These integrations have been thoroughly reviewed, so they are much less likely to contain obvious security issues. If the integration does not exist, you can try a custom component that is part of the HACS repository. These custom components are riskier, but they often show GitHub stars and open issues so you can get an idea of how reliable they are.
Most custom components should be open source so you can review the code; Ambiance-coded embeds may include the name of the AI tool used to create them as one of the authors. If you have no idea about the code, you can ask an AI chatbot to review the code and look for security vulnerabilities or other obvious red flags. It may not be completely accurate, but if it detects major issues, you should consider it a strong warning sign to avoid this integration.
Ultimately, you need to decide if the proposed feature is worth the risk. Installing an ambiance-coded app that gives you a slightly nicer-looking dashboard probably isn’t worth risking your smart home security.
Vibe-coded integrations are a real risk
While vibe coding can help you create integrations that work, it doesn’t mean they will work securely. After experiencing the nightmare of having to rebuild my smart home from scratch, using ambiance-coded apps really isn’t worth the risk.
