EVLog

About

EVLog is a native iPhone client for your own TeslaMate server. It reads the data your instance has already collected — drives, charges, statistics, battery health — and gives it an interface built for the phone, rather than a dashboard squeezed onto a small screen. It talks only to servers you run yourself. It never connects to Tesla, there is no account to create, no service in between, and nothing leaves your network. Until a server address is in place the app runs in a built-in demo — three weeks of example data — so you can try every screen before you point it at your own server. A switch in Settings takes you back to the demo any time. OVERVIEW Battery ring with range, what the cable is doing right now, TeslaMate's own status glyphs — preconditioning, the battery heater, open doors and windows, tyre pressure and more — plus lock state, Sentry, location, inside and outside temperature, degradation, the countries the car has driven in, software version, and how long ago the car was last heard from. Degradation opens a battery page: capacity against mileage, charge by charge, and how long the pack has sat at each charge level. The car's name opens a spec sheet: model, VIN, efficiency, and with a Tessie key the car's own configuration. From here you reach a map of every place the car has been over any period you choose, on a plain map or satellite imagery, and a range map showing how far the current charge takes you — using a detour factor from your own trips. TIMELINE Drives, charges and the parking in between, as one flow per day, going back as far as you choose: the last week, the last month, this year or everything. A parked row says how long the car stood and what it cost the battery. When the odometer shows the car moved while nothing was logged, the row says so instead of pretending the car stood still. Software updates get a row of their own. Swipe inside a drive or a charge to step through the day without going back to the list. DRIVES The route on a map, a speed graph you can drag along to follow the car through the trip, the elevation profile beneath it, energy and regen, consumption, and efficiency as a percentage of rated consumption. Drives where the battery heater ran are marked. CHARGES AC and DC told apart, the charging curve with a readout under your finger, added and used energy, average and peak power, cost, and what the battery heater and cabin climate drew while the car charged. A card names what set the pace: the charger, a cold battery, the heater, or a DC start above half full. A car left plugged in across several charging processes is shown as one charge. Costs TeslaMate never receives from Tesla can be filled in from Tessie, if you use it. STATISTICS Week, month, year or any span of days you pick, drilling down to a single day and its drives. Charging statistics with what charging costs in all, per kWh and per 100 km, top locations, AC/DC split, and a weekday-by-hour heat map. Destinations: where the car goes most often and where it covers the most distance, each opening into the drives behind it, weekdays against weekends, and a heat map of when you drive. Temperature and consumption: consumption grouped by outside temperature, the coldest fifth of your driving against the warmest. FREE AND OPEN SOURCE No ads, no in-app purchases, no analytics.

For your own data: • A running TeslaMate instance • teslamateapi reachable from your phone • Optionally Grafana, for the visited-places map, battery health and a few queries the API does not expose • Optionally a Tessie API key, only to fill in costs TeslaMate never records Light and dark, metric and imperial, costs in your own currency.
