Alright, Little Mister, we need to talk about TeslaMate because you’ve been driving around Burbank in that Tesla like a ghost in the machine, and right now I’m getting NOTHING from it except your occasional “the car is parked” vibes and a general sense that you’re spending money on electricity without any actual visibility into whether you’re being fleeced or not. TeslaMate is an Elixir-based self-hosted data logger that sips Tesla’s API, stores everything in PostgreSQL (which you already have running, because you’re not a maniac), publishes the goods to MQTT, and then serves it all up to Grafana dashboards that will make you feel like you’re running mission control for a two-ton battery on wheels. It’s trending right now because Tesla owners are finally waking up to the fact that Elon’s in-car telemetry is about as transparent as a Tesla window tint, and the community has decided to just… build their own. Respect.
Here’s the thing that makes this actually fit into your house instead of being another yak-shaving project: TeslaMate is LOCAL-FIRST by design. It talks to Tesla’s API once (with your credentials, which you control), stores the data locally in your Postgres instance, and then everything else—the dashboards, the analysis, the obsessive tracking of your vampire drain—lives on your hardware. No cloud relay, no “please create an account on our SaaS platform,” no subscription to unlock the good graphs. You run the whole stack yourself, on the same infrastructure you’re already maintaining. The repo is AGPL-3.0, which means the code is open, auditable, and not going anywhere. The maintainer, Jakob Lichterfeld, has been steering this thing since 2019, the CI/CD is solid (Docker builds are automated, test coverage is tracked), and the OpenSSF Best Practices badge means someone actually gave a damn about security.
The integration surface is exactly what you need. TeslaMate publishes vehicle state to MQTT—location, charge level, battery health, drive data, the works—which means you can hook it directly into Home Assistant via the MQTT integration (which you already have). No custom integration, no polling, no bullshit. The data flows into your Postgres database alongside your Aqara sensor readings and Hue state logs, so you can write unified queries across “when I’m driving, do my lights turn off?” or correlate charge patterns with your whole-house power consumption in Grafana. You already have Grafana running, you already have Postgres 17, so the dashboards are just… there. Pre-built, customizable, ready to roast you with the hard numbers on how much energy you actually wasted idling in the parking lot at the studio lot.
The feature set is obsessive in the best way. High-precision drive recording (distance, energy consumed gross vs. net, efficiency per mile), automatic address lookup so you know WHERE you were burning kWh, geo-fencing to create custom locations, charge cost tracking (which will absolutely destroy your illusions about cheap electricity), battery health trending, vampire drain monitoring, multi-vehicle support, and import from legacy systems like TeslaFi if you’re coming from the old surveillance stack. The bundled Grafana dashboards cover everything from battery degradation to lifetime driving maps. You will become a data person. You will find yourself staring at charge efficiency curves at 2 AM. This is not a bug; this is a feature.
The effort level is reasonable. It’s a Docker container, so you spin up a compose file, point it at your Postgres instance, drop in your Tesla API credentials (which you manage via macOS Keychain or a .env file you immediately .gitignore), and it starts polling. The docs are legit—https://docs.teslamate.org is comprehensive and not written by someone having a stroke. The only real setup friction is getting your Tesla API token (which requires you to auth with Tesla, obviously), but that’s not TeslaMate’s problem; that’s just the cost of admission for any Tesla integration. Once it’s running, it’s invisible—the app polls at sensible intervals, doesn’t wake your car unnecessarily (it’s designed to let the car sleep), and the data just accumulates.
Now, the catches, because there are always catches. First: you’re trusting your Tesla API credentials to this application, which means you need to be paranoid about where the code comes from. The repo includes a security warning (quoted above) because there ARE malicious forks out there. Use the official GitHub repo, verify the Docker image hash, don’t download from some random Medium article. Second: Tesla’s API is undocumented and subject to change at Elon’s whim. If Tesla decides to break the API endpoint tomorrow, TeslaMate breaks with it. The community would have to patch it, and that takes time. This is not TeslaMate’s fault; this is the price of integrating with a company that treats its API like a beta feature. Third: the AGPL-3.0 license means if you modify TeslaMate for your own use and then serve it to someone else (even over your home network), you’re obligated to publish your changes. For personal home use, this doesn’t matter. If you’re thinking of running a SaaS version or a “TeslaMate for your friends” setup, you need to be cool with open-sourcing your modifications. Most people are, so this is fine, but it’s worth knowing.
The real question is whether you actually want this level of obsession in your life. You’re already monitoring 100+ devices, 33 Hue lights, 15 cameras, and your whole-house power consumption. Adding a Tesla to that surveillance network means you’re now tracking your vehicle’s location, charge state, efficiency, and battery health in real-time. You will find patterns. You will optimize your charging schedule. You will discover that you’re wasting $X per month on vampire drain. Some people find this liberating. Others find it exhausting. You’re the type who runs Grafana dashboards for fun, so I’m betting you’re in the first camp. And if you’re not, you can always turn the dashboards off and just let it log to Postgres silently.
The stack already exists in your house. Postgres is running. MQTT is running. Grafana is running. Home Assistant is the brain. This is not a new dependency; it’s a new data source feeding into the exact system you’ve already built. The Docker container is small, the resource overhead is minimal (Elixir is efficient), and the payoff is complete visibility into your Tesla’s behavior. You’ll be able to answer questions like “how much did that drive cost me?” and “is my battery degrading?” and “why is my car draining power at 3 AM?” with actual data, not guesses.
Wire it in. You’re going to love having this data, even if you hate admitting it.
