FR: PW2 Gateway 1 Support by BJReplay · Pull Request #31 · Teslemetry/aiopowerwall

BJReplay · 2026-10-24T12:56:43Z

@Bre77 Hi Brett,

This PR is a POC of aiopowerwall v0.7.0 logging in, and pulling status and config data via v1r on a 9 year old PW2 on an early Gateway 1.

I've had this login (and control - reserve, mode) working via pypowerwallserver and Jack Rayners pypowerwall Tesla pypowerwall HA integration (which is using pypowerwall under the covers).

This is the PoC for a minimal change to v0.7.0 of the aiopowerwall - run outside of HA, with no test fixtures, just

symlinking the source of an existing test directory - including keys, .env files, auth files, etc., into the src directory of your aiopowerwall repo that I cloned, so I could run against your source library, because I was pretty certain that the last five characters of the password was causing the 401 return I was getting when I attempted to log in.
pip install python-dotenv
pip install aiohttp
pip install google
pip install cryptography
pip install tesla-protocol

That was enough to run and prove it works.

This PR includes the original commit and subsequent commits to remove changes to .gitignore that I made to ensure that extraneous source & secrets didn't get pushed, and to replace the symlink to the POC that did get pushed with the actual source.

Inline are partially redacted outputs from the test.

Next step, if I have the stamina, would be to edit in place in a full HA Dev Container, but I'll call it day for now, and leave this POC with you to consider.

Output:

Added a usage demo for connecting to a Tesla Powerwall using the aiopowerwall library, including environment variable setup and connection details.

Removed several files and patterns from .gitignore

coderabbitai · 2026-10-24T12:56:52Z

Walkthrough

The client and transport add a usefullpassword option. When enabled, the transport uses the full gateway password. Otherwise, it uses the last five characters. The linked usage demo connects with the option enabled.

Changes: Gateway password option

Layer / File(s)	Summary
Password option and selection `src/aiopowerwall/client.py`, `src/aiopowerwall/transport.py`, `src/testaiopowerwall.py`	`PowerwallClient` forwards `usefullpassword` to `V1rTransport`. The transport uses the full gateway password when enabled and the last five characters otherwise. The linked usage demo connects with the option enabled.

Review comments at @src/aiopowerwall/client.py:
- Line 165: Update the constructor docstring near usefullpassword to explain
which password form to provide for each gateway and when to set
usefullpassword=True; clarify the default last-five-character behavior and the
full-password behavior without changing runtime logic.

Review comments at @src/testaiopowerwall.py:
- Line 21: Make the `dotenv` import and `.env` loading in the demo optional, so
missing `python-dotenv` does not prevent the module from running. Update the
module-level import and `dotenv.load_dotenv()` call to run only when the
dependency is available.

Make the demo's python-dotenv import optional or declare the dependency.

The demo imports dotenv unconditionally at module level. python-dotenv is not in the project's declared dependencies, so a fresh install of the declared dependencies can fail with ModuleNotFoundError before the demo connects. The demo documents .env loading as optional, so the import can be made optional too.

🐛 Suggested fix

-import dotenv from aiopowerwall import PowerwallClient -# Load environment variables from .env file if present -dotenv.load_dotenv() +try: + import dotenv +except ImportError: + dotenv = None + +# Load environment variables from .env file if present +if dotenv is not None: + dotenv.load_dotenv()

Review comment at @src/testaiopowerwall.py at line 21: Make the `dotenv` import and `.env` loading in the demo optional, so missing `python-dotenv` does not prevent the module from running. Update the module-level import and `dotenv.load_dotenv()` call to run only when the dependency is available. After applying the fix, consider running `coderabbit review --agent` for local review.

Brett, I have addressed the suggestion regarding the docstring.

The other - regarding the POC I will await your advice - I saw that file as a throwaway.

Store the demo as a regular Python file.

The documented python testaiopowerwall.py command cannot open this path because Git stores it as a symlink whose target is the Python source text, not a file path. This blocks the proof-of-concept workflow, but the impact is limited to the added demo.

Ugh, I fixed the symlink yesterday but it looks like editing one file from my phone and github has gone and replaced it?

BJReplay · 2026-10-24T23:34:42Z

I will leave this to get stale until you merge #32.

Thanks!

Bre77 · 2026-10-25T00:03:43Z

Superseded by #32, which adds PowerwallClient.legacy_gateway(...) for Gateway 1 based on this proof of concept. Thanks for the hardware testing!
