HaCasa
🏠 HaCasa Nova: the HaCasa reboot. A room-first Home Assistant panel, built on the Homio design by iamtherufus.
Runs with mockssource: GitHubhomepageJavaScriptMITcommit b9ad6aadf9a0
JavaScript, MIT licensed. The project labels itself: custom panel, dashboard, hacs, home assistant, homeassistant, homio, lit and lovelace.
HaCasa runs, with stand-ins for the services it depends on. An Argusic agent installed it in 2 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.
HaCasa Nova 3.0.0 builds from source with npm install && npm run build, serves via HTTP with the dev mock backend, and renders a complete panel UI in both panel mode and card mode in a headless browser.
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 92 of 100 (the mean of this project's run scores).
At a glance
Subject data from GitHub, linked at the top of this page, refreshed . Test data by Argusic (CC BY 4.0); every number links to a run page with the full log, the recording, and their sha256 hashes.
What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
- Install time
- 2 minutes
- Cold machine to finish
- 5 minutes
- Errors hit and fixed
- 0 hit, 0 fixed with no human help
- How the result was proved
- Playwright headless Chromium loaded http://127.0.0.1:8099/repo/dev/index.html (panel mode) and http://127.0.0.1:8099/repo/dev/card.html (card mode). Shadow DOM inspection confirmed rendered content: navigation with room names (Living room, Kitchen, Bedroom, etc.), climate card showing 'Heating 21.5°', media player showing 'Playing B2b - Charli xcx', energy widget showing '6.8 kWh used today', attention notifications, weather display, and more.
- Model tokens used
- 50,706
- Exact commit tested

What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
- Behaviour against real services
- this run was verified against stand-in services only

Now I have all the information needed. Let me compile the results.Replay the whole session, every command from a clean machine to this point.
How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Installed in 2 minutes.
- Nothing broke on the way: zero errors between clone and running.
- Licensed MIT, as reported by its host.
What did not, or is not known
- Only reached a running state against stand-in services, so nothing here proves it works against the real ones.
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
Also tested, in the same area
Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

[](https://argusic.com/subject/hacasa)Questions
- Does HaCasa run?
- HaCasa runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 2 minutes, hitting 0 errors on the way, and recorded the session.
- How did Argusic test HaCasa?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit b9ad6aadf9a0. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test HaCasa?
- The run that produced this verdict cost $0.07: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does HaCasa take to install?
- 2 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does HaCasa need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing HaCasa?
- Nothing did, in the recorded run: zero errors between clone and running.
- Where is the evidence for HaCasa?
- The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
