evcc
solar charging ☀️🚘
Runs with mockssource: GitHubhomepageGoMITcommit 0972249b9242
Go, MIT licensed. The project labels itself: battery, charger, eebus, emobility, golang, home automation, modbus and mqtt.
evcc runs, with stand-ins for the services it depends on. An Argusic agent installed it in 15 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.
evcc builds from source, all 88 Go test packages pass, and the binary serves the full web UI and REST API in demo mode returning HTTP 200 on both / and /api/state.
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
- 15 minutes
- Cold machine to finish
- 14 minutes
- Errors hit and fixed
- 0 hit, 0 fixed with no human help
- How the result was proved
- make test exited 0, 88 Go packages pass, 0 failures. ./evcc --demo serves HTTP 200 on / and /api/state, returns HTML with evcc meta tags.
- Model tokens used
- 274,356
- Exact commit tested
- 0972249b9242
- Container image
- sha256:cdd920bce783
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
The end of the recording
The last lines of the terminal session that decided this verdict, exactly as they were recorded.

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 15 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.

[](https://argusic.com/subject/evcc)Questions
- Does evcc run?
- evcc runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 15 minutes, hitting 0 errors on the way, and recorded the session.
- How did Argusic test evcc?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 0972249b9242. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test evcc?
- The run that produced this verdict cost $0.08: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does evcc take to install?
- 15 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 evcc need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing evcc?
- Nothing did, in the recorded run: zero errors between clone and running.
- Where is the evidence for evcc?
- 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.
